Abstract
Measles, mumps, and rubella (MMR) are highly infectious viral diseases affecting young children and have high secondary attack rates. Present MMR vaccines show consistent seroconversion rates for anti-measles and anti-rubella antibodies with variable responses for anti-mumps antibodies. Most common strains for MMR vaccines, currently available in India, are the Edmonston-Zagreb measles strain, Leningrad Zagreb (L-Z) mumps strain, and the RA 27/3 rubella strain. L-Z strain of mumps virus has been found to be associated with aseptic meningitis by different studies from different parts of the world including India. Recently, a novel freeze-dried MMR vaccine developed by Zydus Lifesciences (Zyvac MMR) contains Edmonston Zagreb measles strain, Hoshino mumps strain, and RA 27/3 rubella strain. The Hoshino strain is WHO approved and was found to induce interferon gamma production. This review article aims to provide a comprehensive appraisal of the data available on the safety and immunogenicity of the novel MMR vaccine.

Abstract
Given the higher susceptibility to infectious disease in patients receiving immunosuppressive therapies for inflammatory dermatologic conditions, immunization is important in this population. While live vaccines protect against life-threatening diseases, they can be harmful in immunosuppressed patients given the risk of replication of the attenuated pathogen and adverse reactions. The utilization of live vaccines in immunosuppressed patients depends on multiple factors such as the vaccine and therapy regimen. To provide an overview of evidence-based recommendations for the use of live vaccines in patients receiving immunosuppressive therapies for dermatological conditions. A literature search of the PubMed database was performed using keywords live vaccine, live-attenuated vaccine, dermatology, immunosuppressed, and immunocompromised, and specific immunosuppressive therapies: corticosteroids, glucocorticoids, methotrexate, azathioprine, cyclosporine, mycophenolate mofetil, biologics. Relevant articles written in English were included. Using these keywords, 125 articles were reviewed, of which 28 were ultimately selected. Recommendations for live vaccines can be determined on a case-by-case basis. Measles, mumps, rubella, varicella (MMRV) vaccines may be safely administered to patients on low-dose immunosuppressive agents while the yellow fever vaccine is typically contraindicated. It may be safe to administer live MMRV boosters to children on immunosuppressive therapies and the live herpes zoster vaccine to patients on biologics. Given poor adherence to immunization guidelines in immunosuppressed patients, dermatologists have a critical role in educating patients and general practitioners regarding live vaccines. By reviewing a patient's vaccination history and following immunization guidelines prior to initiating immunosuppressive therapies, physicians can mitigate morbidity and mortality from vaccine-preventable diseases.

Abstract
BACKGROUND AND OBJECTIVE Current regulatory labeling recommends avoiding live vaccine use in dupilumab-treated patients. Clinical data are not available to support more specific guidance for live or live attenuated vaccines administration in dupilumab-treated patients. METHODS Children (6 months-5 years old) with moderate-to-severe atopic dermatitis (AD) enrolled in a phase 2/3 clinical trial of dupilumab (LIBERTY AD PRESCHOOL Part A/B; NCT03346434) and subsequently participated in the LIBERTY AD PED-OLE (NCT02612454). During these studies, protocol deviations occurred in nine children who received measles, mumps, rubella (MMR) vaccine with or without varicella vaccine; five with a ≤12-week gap between dupilumab administration and vaccination and four with a >12-week gap after discontinuing dupilumab. RESULTS Nine children (1 female; 8 male) had severe AD at baseline (8-56 months old). Of the nine children, five had a ≤12-week gap ranged 1-7 weeks between dupilumab administration and vaccination who received MMR vaccine (n = 2) or MMR and varicella vaccines (n = 3); among these, one resumed dupilumab treatment as early as 2 days and four resumed treatment 18-43 days after vaccination. No treatment-emergent adverse events, including serious adverse events and infections, were reported within the 4-week post-vaccination period in any children. CONCLUSIONS In this case series of dupilumab-treated children with severe AD who received MMR vaccine with or without varicella vaccine, no adverse effects (including vaccine-related infection) were reported within 4 weeks after vaccination. Further studies are warranted to evaluate the safety, tolerability, and immune response to live attenuated vaccines in dupilumab-treated patients.

Abstract
BACKGROUND Antibody persistence of a whole-cell pertussis-containing hexavalent vaccine (DTwP-IPV-HB-PRP~T) and its co- or sequential administration with measles, mumps, rubella (MMR) vaccine were evaluated. METHODS Phase III, open-label, randomized, multicenter study in India. Healthy toddlers 12-24 months of age who had received DTwP-IPV-HB-PRP~T or separate DTwP-HB-PRP~T+IPV primary vaccination at 6-8, 10-12 and 14-16 weeks of age received a DTwP-IPV-HB-PRP~T booster concomitantly with MMR (N = 336) or 28 days before MMR (N = 340). Participants had received a first dose of measles vaccine. Immunogenicity assessment used validated assays and safety was by parental reports. All analyses were descriptive. RESULTS All participants had prebooster anti-T ≥0.01 IU/mL and anti-polio 1 and 3 ≥8 1/dil, and ≥96.5% had anti-D ≥0.01 IU/mL, anti-HBs ≥10 mIU/mL, anti-polio 2 ≥8 1/dil and anti-PRP ≥0.15 µg/mL; for pertussis, antibody persistence was similar in each group. Postbooster immunogenicity for DTwP-IPV-HB-PRP~T was similar for each antigen in each group: ≥99.5% of participants had anti-D ≥0.01 IU/mL, anti-T ≥0.01 IU/mL, anti-polio 1, 2 and 3 >8 1/dil, anti-HBs ≥10 mIU/mL and anti-PRP ≥1 µg/mL; for pertussis, vaccine response was similar in each group [72.0%-75.9% (anti-PT), 80.8%-81.4% (anti-FIM), 77.6%-79.5% (anti-PRN), 78.2%-80.8% (anti-FHA)]. There was no difference in MMR immunogenicity between groups, and no difference in DTwP-IPV-HB-PRP~T booster immunogenicity based on the primary series. There were no safety concerns. CONCLUSIONS DTwP-IPV-HB-PRP~T antibody persistence was similar to licensed comparators. Booster immunogenicity was robust after DTwP-IPV-HB-PRP~T with or without MMR, and MMR immunogenicity was not affected by coadministration with DTwP-IPV-HB-PRP~T.

Abstract
OBJECTIVES During the COVID-19 pandemic, there was a decline in vaccine coverage, and the implementation of combined vaccines and co-administration strategies emerged as potential solutions to alleviate this predicament. Our objective is to delve into the concurrent administration of the sabin-strain-based inactivated poliovirus vaccine (sIPV), the diphtheria-tetanus-acellular pertussis vaccine (DTaP), and measles-mumps-rubella vaccine (MMR), with the intention of bridging the evidentiary gap pertaining to vaccine co-administration in Chinese infants, and to ensure a safe and effective vaccination strategy, ultimately leading to an augmentation in immunization coverage. METHODS This study was a follow-up trial of the "Immunogenicity and safety of concomitant administration of the sIPV with the DTaP vaccine in children: a multicenter, randomized, non-inferiority, controlled trial." Blood samples were collected on day 0 and day 30, and serum antibody levels were detected to measure antibody responses to each of the antigens. Local and systemic adverse events were monitored and compared among groups. This study is the first to fill the knowledge gap in China regarding the safe and effective combined vaccination of sIPV, DTaP, and MMR vaccines. RESULTS The geometric mean titer of the poliovirus types I, II, and III neutralizing antibodies were 1060.22 (95% CI: 865.73-1298.39), 1537.06 (95% CI: 1324.27-1784.05), and 1539.10 (95% CI: 1296.37-1827.29) in group I on day 30; geometric mean titer of antibodies against DTaP and MMR in the simultaneous vaccination group was non-inferior to those in the DTaP alone and MMR alone group. Reporting rates of local and systemic adverse reactions were similar between groups and no serious adverse events were reported throughout the clinical study period. CONCLUSION Co-administration of the sIPV, DTaP, and MMR was safe and did not impact immunogenicity, which would help to mitigate administrative costs and enhance vaccine coverage rates.

Abstract
Objective: Cases of cow's milk allergy (CMA) who reacted to measles or measles, mumps, and rubella (MMR) vaccines containing alpha-lactalbumin have been reported. The purpose of this study was to assess patients with CMA who received measles or MMR vaccines containing alpha-lactalbumin, as well as the characteristics of those who developed reactions to these vaccines. Study Design: Patients followed up in the allergy clinic for CMA and who received measles or MMR vaccines containing alpha-lactalbumin at 9 or 12 months of age were included in the study, and their characteristics were analyzed retrospectively from the hospital registry system. Results: Forty-nine patients were included in the study. Six patients received the measles vaccine, whereas 43 patients received the MMR vaccine containing alpha-lactalbumin. Vaccine skin tests were performed on these 6 patients. One patient had a positive intradermal test, so an alternative vaccine not containing alpha-lactalbumin was administered. The other 5 patients were vaccinated, and no reaction was observed. Anaphylaxis was observed in 3 of 43 patients who received the MMR vaccine containing alpha-lactalbumin. In all of these patients, the first reaction to dairy products was anaphylaxis. In 2 of those patients, cow's milk-specific IgE (spIgE) levels were >100 kU/L, and alpha-lactalbumin-spIgE levels were also high at 97 and 90 kU/L. The third patient's cow's milk-spIgE level was 15.9 kU/L, whereas the alpha-lactalbumin-spIgE level was 0.04 kU/L. Conclusion: Especially in patients with an initial reaction of anaphylaxis to dairy products and high cow's milk-spIgE levels, the risk of reaction is high with the MMR vaccine.

Abstract
INTRODUCTION Studies on quadrivalent measles, mumps, rubella, and varicella (MMRV) vaccines have indicated a twofold increased relative risk of febrile convulsion (FC) after the first dose compared to MMR and V administered at the same medical visit (MMR+V). AREAS COVERED This narrative review contextualizes FC occurrence after the first MMRV vaccine dose from a clinical perspective and outlines approaches to attenuate FC occurrence post-vaccination. EXPERT OPINION While the relative FC risk increases after the first dose of MMRV compared to MMR+V vaccine in measles-naïve infants, the attributable risk is low versus the overall FC risk in the pediatric population triggered by other causes, like natural exposure to pathogens or routine vaccination. No increased risk of FC has been reported after MMRV co-administration with other routine vaccines compared to MMRV alone. Based on our findings and considering the MMRV vaccination benefits (fewer injections, higher coverage, better vaccination compliance), the overall benefit-risk profile of MMRV vaccine is considered to remain positive. Potential occurrence of FC in predisposed children (e.g. with personal/family history of FC) may be attenuated if they receive MMR+V instead of MMRV as the first dose. It is also important to monitor vaccinees for fever during the first 2 weeks post-vaccination.

Abstract
BACKGROUND Nonpharmacological interventions are needed to reduce pain during vaccine administration in infants. PURPOSE To determine the effect of the Buzzy device, which is a combination of cold and vibration, on pain during measles-mumps-rubella (MMR) vaccine administration in 12-month-old infants. METHODS A prospective randomized controlled experimental research design was used. RESULTS A total of 60 infants were included in the study. During and after vaccine injection, pain scores of infants who had the Buzzy device were significantly lower than those of infants in the control group ( P = .001). CONCLUSIONS Buzzy application may be an effective method in reducing pain during MMR vaccine administration. Use of the device is recommended for infants receiving vaccinations.

Abstract
This article traces the origin, sustenance and implications of a persistent rumour that is responsible for low measles mumps and rubella (MMR) vaccination uptake in the Somali diaspora in a number of countries across the globe. The rumour stipulates that the MMR vaccine - the silent shot - causes autism spectrum disorder (ASD). Although the association between MMR and ASD is non-causal, and various public health initiatives have promoted health information campaigns, the rumour continues to circulate in the Somali diaspora in many countries, including Sweden. This paper shows that there are valid reasons for this. The findings from this paper draw on a systematic scoping review and qualitative interview data from Sweden. The results show that the Somali community experiences higher than average rates of ASD compared to the general population. Moreover, ASD does not exist in the Somali language or their home country, is considered a Western disease that only affects Somali children in the diaspora, and is a highly stigmatised disease. Also, the Somali diaspora has had negative experiences with ASD diagnosis and care. The rumour has been sustained by the absence of an answer to their ASD fear and through active diaspora networks on social media. The network that surrounds the rumour has arguably further helped to create an epistemic community for a community whose concerns have been silenced.

The files of 182 patients were accessed from the pediatric rheumatology biological therapy archive, and the vaccination status of these children was obtained by accessing electronic records. Of 182 patients, 14 patients were vaccinated with MMR booster dose. Thirteen of the patients were followed up with a diagnosis of juvenile idiopathic arthritis and one with colchicine-resistant familial Mediterranean fever. None of the patients had disease exacerbation after vaccination, and three patients had mild side effects consisting of rash, angioedema, joint pain, and fatigue. Conclusion: This study supports the data regarding evidence of the safety of MMR booster dose administration in children with rheumatic diseases receiving bDMARDs. What is Known: • MMR booster is avoided in immunocompromised pediatric patients receiving bDMARDs except in specific conditions. What is New: • The MMR booster dose may be safe in children with PedRD receiving bDMARDs or bDMARDs with MTX. These bullets can be added to the manuscript.

Abstract
The risk of geographic transmission of infectious diseases due to air travel varies greatly. Our aim is to survey empirical data that provide a retrospective historical perspective on measles and rubella. This study used the open data website provided by the Taiwan Centers for Disease Control (TCDC) to extract the reported numbers of measles and rubella case between 2011 and 2020. There were 306 cases of measles and 135 cases of rubella. The incidence of measles and rubella per million population were 0 to 6.0 and 0 to 2.6, respectively. There was a gradual increase in the numbers of cases in those aged 20-39 years, and distinct duration patterns. It indicated that the risk of contracting rubella has significantly decreased in the last 5 years. Measles cases aged 20 to 39 years accounted for 72.5% of all cases. Rubella cases aged 20 to 39 years accounted for 59.3% of all cases. The male and residency in the Taipei metropolitan area or northern area were identified as potential risk factors for measles and rubella. Coverage with the first dose of the measles, mumps and rubella (MMR) vaccine in Taiwan increased from 97.31% to 98.86%, and the uptake rate of the second dose of the MMR vaccine increased from 95.73% to 98.39% between 2010 and 2020. Furthermore, the numbers of imported cases of measles (n = 0) and rubella (n = 0) reported during the coronavirus disease 2019 (COVID-19) pandemic were lower than those from 2011 to 2019. Measles and rubella cases were imported most frequently from Cambodia and Vietnam. This study represents the first report of confirmed cases of acquired measles and rubella from surveillance data of the TCDC between 2011 and 2020, also demonstrates that the numbers of cases of measles and rubella significantly decreased in Taiwan during the COVID-19 pandemic.

Abstract
Genital warts are caused by several strains of Human Papilloma Viruses. Although asymptomatic in most cases, they can be psychologically and physically distressing for patients. Recently, intralesional immunotherapy using different antigens—such as Bacille Calmette–Guerin vaccine, candida antigen and measles, mumps, and rubella (MMR) vaccine—have shown promising efficacy in the treatment of genital warts. We report two cases in Omani males who presented to the Dermatology Department at Barka Polyclinic with recalcitrant genital warts that resolved completely with intralesional injection of the MMR vaccine.

Abstract
OBJECTIVES To determine whether children aged 4-7 years with a diagnosis of autism spectrum disorders (ASD) were at increased risk of fever, febrile seizures, or emergency department (ED) visits following measles- or pertussis-containing vaccines compared with children without ASD. METHODS The study included children born between 1995-2012, aged 4-7 years at vaccination, and members of six healthcare delivery systems within Vaccine Safety Datalink. We conducted self-controlled risk interval analyses comparing rates of outcomes in risk and control intervals within each group defined by ASD status, and then compared outcome rates between children with and without ASD, in risk and control intervals, by estimating difference-in-differences using logistic regressions. RESULTS The study included 14,947 children with ASD and 1,650,041 children without ASD. After measles- or pertussis-containing vaccination, there were no differences in association between children with and without ASD for fever (ratio of rate ratio for measles-containing vaccine = 1.07, 95% CI 0.58-1.96; for pertussis-containing vaccine = 1.16, 95% CI 0.63-2.15) or ED visits (ratio of rate ratio for measles-containing vaccine = 1.11, 95% CI 0.80-1.54; for pertussis-containing vaccine = 0.87, 95% CI 0.59-1.28). Febrile seizures were rare. Pertussis-containing vaccines were associated with small increased risk of febrile seizures in children without ASD. CONCLUSION Children with ASD were not at increased risk for fever or ED visits compared with children without ASD following measles- or pertussis-containing vaccines. These results may provide further reassurance that these vaccines are safe for all children, including those with ASD.

Abstract
Linear IgA bullous dermatosis (LABD) is a mucocutaneous autoimmune blistering disease affecting both adults and children. It is caused by IgA antibodies targeting multiple antigens along the basement membrane zone, leading to disruption of dermoepidermal junction and development of bullous lesions which often presents in characteristic arrangement. Although most LABD cases have been reported to be idiopathic, different triggers have been described, including several drugs and infection. However, the occurrence of vaccine-induced cases of LABD is not widely known and accepted due to the few reports available. We present two cases of LABD occurred following different triggers, rising the suspicion for a possible pathogenetic role of vaccines.

Abstract
BACKGROUND The measles-mumps-rubella vaccine was withdrawn from the National Immunization Program in 1993 because aseptic meningitis was reported as a post-vaccination adverse reaction in Japan. This study aimed to measure the uptake of and determinants influencing mumps vaccination, including concerns about adverse reactions. METHODS We conducted this cross-sectional survey for all parents whose children underwent 18-month health checkups in Kanazawa City between October 2019 and February 2020. Community nurses interviewed the parents using a unified questionnaire, and 1422 parents responded. RESULTS Based on records from maternal and child health handbooks, the mumps vaccination rate was 55.6%. The most common reason for parents not vaccinating their children against mumps was that "it is not a routine vaccine" (35.9%), whereas "concern about adverse reactions" accounted for only 2.2%. In multivariate analysis, the significantly positive factors associated with vaccination against mumps were children whose parents knew that adverse reactions were fever, rash, diarrhea, and vomiting; had received a recommendation for vaccination from their family members; had read the Vaccination Guide issued by the city; vaccinated with other voluntary vaccines or treated for gastroenteritis; and had a deep general understanding of vaccination. Conversely, the significantly negative factor was children whose parents had not received any recommendation for vaccination. CONCLUSION The mumps vaccination rate could be improved by adding the mumps vaccine in the routine vaccination program and educating parents by disseminating correct information on mumps and the mumps vaccine, and by primary care physicians routinely recommending vaccination.

Abstract
BACKGROUND Measles, mumps, rubella, and varicella (chickenpox) are serious diseases that can lead to serious complications, disability, and death. However, public debate over the safety of the trivalent MMR vaccine and the resultant drop in vaccination coverage in several countries persists, despite its almost universal use and accepted effectiveness. This is an update of a review published in 2005 and updated in 2012. OBJECTIVES To assess the effectiveness, safety, and long- and short-term adverse effects associated with the trivalent vaccine, containing measles, rubella, mumps strains (MMR), or concurrent administration of MMR vaccine and varicella vaccine (MMR+V), or tetravalent vaccine containing measles, rubella, mumps, and varicella strains (MMRV), given to children aged up to 15 years. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2019, Issue 5), which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (1966 to 2 May 2019), Embase (1974 to 2 May 2019), the WHO International Clinical Trials Registry Platform (2 May 2019), and ClinicalTrials.gov (2 May 2019). SELECTION CRITERIA We included randomised controlled trials (RCTs), controlled clinical trials (CCTs), prospective and retrospective cohort studies (PCS/RCS), case-control studies (CCS), interrupted time-series (ITS) studies, case cross-over (CCO) studies, case-only ecological method (COEM) studies, self-controlled case series (SCCS) studies, person-time cohort (PTC) studies, and case-coverage design/screening methods (CCD/SM) studies, assessing any combined MMR or MMRV / MMR+V vaccine given in any dose, preparation or time schedule compared with no intervention or placebo, on healthy children up to 15 years of age. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the methodological quality of the included studies. We grouped studies for quantitative analysis according to study design, vaccine type (MMR, MMRV, MMR+V), virus strain, and study settings. Outcomes of interest were cases of measles, mumps, rubella, and varicella, and harms. Certainty of evidence of was rated using GRADE. MAIN RESULTS We included 138 studies (23,480,668 participants). Fifty-one studies (10,248,159 children) assessed vaccine effectiveness and 87 studies (13,232,509 children) assessed the association between vaccines and a variety of harms. We included 74 new studies to this 2019 version of the review. Effectiveness Vaccine effectiveness in preventing measles was 95% after one dose (relative risk (RR) 0.05, 95% CI 0.02 to 0.13; 7 cohort studies; 12,039 children; moderate certainty evidence) and 96% after two doses (RR 0.04, 95% CI 0.01 to 0.28; 5 cohort studies; 21,604 children; moderate certainty evidence). The effectiveness in preventing cases among household contacts or preventing transmission to others the children were in contact with after one dose was 81% (RR 0.19, 95% CI 0.04 to 0.89; 3 cohort studies; 151 children; low certainty evidence), after two doses 85% (RR 0.15, 95% CI 0.03 to 0.75; 3 cohort studies; 378 children; low certainty evidence), and after three doses was 96% (RR 0.04, 95% CI 0.01 to 0.23; 2 cohort studies; 151 children; low certainty evidence). The effectiveness (at least one dose) in preventing measles after exposure (post-exposure prophylaxis) was 74% (RR 0.26, 95% CI 0.14 to 0.50; 2 cohort studies; 283 children; low certainty evidence). The effectiveness of Jeryl Lynn containing MMR vaccine in preventing mumps was 72% after one dose (RR 0.24, 95% CI 0.08 to 0.76; 6 cohort studies; 9915 children; moderate certainty evidence), 86% after two doses (RR 0.12, 95% CI 0.04 to 0.35; 5 cohort studies; 7792 children; moderate certainty evidence). Effectiveness in preventing cases among household contacts was 74% (RR 0.26, 95% CI 0.13 to 0.49; 3 cohort studies; 1036 children; moderate certainty evidence). Vaccine effectiveness against rubella, using a vaccine with the BRD2 strain which is only used in China, is 89% (RR 0.11, 95% CI 0.03 to 0.42; 1 cohort study; 1621 children; moderate certainty evidence). Vaccine effectiveness against varicella (any severity) after two doses in children aged 11 to 22 months is 95% in a 10 years follow-up (rate ratio (rr) 0.05, 95% CI 0.03 to 0.08; 1 RCT; 2279 children; high certainty evidence). Safety There is evidence supporting an association between aseptic meningitis and MMR vaccines containing Urabe and Leningrad-Zagreb mumps strains, but no evidence supporting this association for MMR vaccines containing Jeryl Lynn mumps strains (rr 1.30, 95% CI 0.66 to 2.56; low certainty evidence). The analyses provide evidence supporting an association between MMR/MMR+V/MMRV vaccines (Jeryl Lynn strain) and febrile seizures. Febrile seizures normally occur in 2% to 4% of healthy children at least once before the age of 5. The attributable risk febrile seizures vaccine-induced is estimated to be from 1 per 1700 to 1 per 1150 administered doses. The analyses provide evidence supporting an association between MMR vaccination and idiopathic thrombocytopaenic purpura (ITP). However, the risk of ITP after vaccination is smaller than after natural infection with these viruses. Natural infection of ITP occur in 5 cases per 100,000 (1 case per 20,000) per year. The attributable risk is estimated about 1 case of ITP per 40,000 administered MMR doses. There is no evidence of an association between MMR immunisation and encephalitis or encephalopathy (rate ratio 0.90, 95% CI 0.50 to 1.61; 2 observational studies; 1,071,088 children; low certainty evidence), and autistic spectrum disorders (rate ratio 0.93, 95% CI 0.85 to 1.01; 2 observational studies; 1,194,764 children; moderate certainty). There is insufficient evidence to determine the association between MMR immunisation and inflammatory bowel disease (odds ratio 1.42, 95% CI 0.93 to 2.16; 3 observational studies; 409 cases and 1416 controls; moderate certainty evidence). Additionally, there is no evidence supporting an association between MMR immunisation and cognitive delay, type 1 diabetes, asthma, dermatitis/eczema, hay fever, leukaemia, multiple sclerosis, gait disturbance, and bacterial or viral infections. AUTHORS' CONCLUSIONS: Existing evidence on the safety and effectiveness of MMR/MMRV vaccines support their use for mass immunisation. Campaigns aimed at global eradication should assess epidemiological and socioeconomic situations of the countries as well as the capacity to achieve high vaccination coverage. More evidence is needed to assess whether the protective effect of MMR/MMRV could wane with time since immunisation.

Abstract
BACKGROUND The safety and immunogenicity of M-M-RII (measles, mumps and rubella virus vaccine live, Merck & Co., Inc., West Point, PA)-the only combined measles, mumps and rubella vaccine licensed for use in the United States-were previously reported in pre- and postlicensure clinical trials conducted from 1988 to 2009. M-M-RII continues to be evaluated as a comparator in clinical trials of other vaccines. Here, we review safety and efficacy data from more recent clinical trials of M-M-RII. METHODS We performed a systematic literature review of trials using M-M-RII published from 2010 to 2019. RESULTS In the 15 studies that met the inclusion criteria, a total of 12,032 subjects were vaccinated: 7667 persons received a first dose only, 2137 participated in 2-dose studies (128 received 1 dose and 2009 received both) and 2063 received a single dose of M-M-RII as their second dose. Dose number was not specified for 165 participants, ≥6 years old, in 2 studies in which a single dose of M-M-RII was administered. Similar to previous reports, M-M-RII was well tolerated and immunogenic when administered alone or concomitantly with other routinely recommended vaccinations. The most common adverse events included transient injection site pain and fever. Serious adverse events were extremely rare, with only 4 probable or potential vaccine-related events reported among the 12,032 participating subjects. CONCLUSIONS In trials published from 2010 to 2019, M-M-RII continued to be safe and immunogenic in all age groups studied. These data, along with the results of earlier trials, indicate that the performance of the vaccine has been consistent across more than 30 years of postlicensure studies.

Abstract
YouTube videos have been used to inform and misinform the public about the safety of vaccines related to health threats such as measles and COVID-19. Understanding how such videos can promote the sharing of accurate vaccine safety information is of the utmost importance if health researchers are to combat the spread of misinformation and encourage widespread uptake of vaccines. Through the lens of prospect theory, this study conducted a 2 (framing: loss v. gain) x 2 (evidence type: episodic v. thematic) x 2 (speaker expertise: expert v. non-expert) between-subject factorial experiment in which a sample of N = 400 US adults over the age of 18 recruited through MTurk were asked their intention to share vaccine safety information with others after watching a manipulated YouTube video. The results showed that loss framing was associated with perceived MMR severity which was, in turn, associated with the likelihood that participants would share MMR vaccine information with others, via any means. However, this process varied depending on the type of evidence delivered, and the expertise of the speaker. Results and limitations are discussed in the context of vaccine communication and social media.

Abstract
Objective: To investigate the immunogenicity and safety of a boost dose of measles, mumps, and rubella combined vaccine (MMR) for children 4 to 6 years old. Methods: Children, aged 4 to 6 years old, had vaccinated with 1 dose of measles and rubella combined vaccine(MR) at the age of 8 months and 1 dose of MMR vaccine at 18-months, were recruited in Shanxi, Inner Mongolia, and Beijing, respectively. All children were assigned into 4, 5 and 6-year-old group. The children who met inclusion and exclusion criteria were vaccinated with 1 dose MMR vaccine, and were collected blood samples before vaccination and 35 to 42 d after the vaccination. During the study period, adverse events were collected at 30 min, 1 d, 2 d, 3 d, 4-12 d, and 13 to 42 days after vaccination. Serum was tested for IgG antibodies against measles, mumps and rubella. Geometric mean concentrations (GMC) of measles, mumps, and rubella antibodies were compared among groups by analysis of variance or non-parametric test. Seropositive rates and adverse event rates were compared among groups by Chi-square test or Fisher exact test. Results: A total of 500 children were included in immunogenicity analysis and 535 children were included in safety analysis. The overall adverse event rate was 20.37%, the most of severity for adverse events was mild. The rates of local and systemic adverse events were 0.37% and 20.00%, respectively. Symptoms of local adverse events were redness. The main systemic adverse events were fever, followed by cough, rash and runny nose. Received a dose of MMR vaccine for booster immunization, the seropositive rates of measles antibody, mumps antibody and rubella antibody were above 99% for all 3 age groups, and there was no significant difference between groups. There were significant differences in mumps antibody GMC among groups (P=0.042), but no significant differences in measles and rubella antibodies GMC. Conclusion: The immunogenicity and safety of a boosted MMR vaccintion in children aged 4, 5 and 6 years were all similar good.

Abstract
BACKGROUND Understanding the safety of vaccines is critical to inform decisions about vaccination. Our objective was to conduct a systematic review of the safety of vaccines recommended for children, adults, and pregnant women in the United States. METHODS We searched the literature in November 2020 to update a 2014 Agency for Healthcare Research and Quality review by integrating newly available data. Studies of vaccines that used a comparator and reported the presence or absence of key adverse events were eligible. Adhering to Evidence-based Practice Center methodology, we assessed the strength of evidence (SoE) for all evidence statements. The systematic review is registered in PROSPERO (CRD42020180089). RESULTS Of 56,603 reviewed citations, 338 studies reported in 518 publications met inclusion criteria. For children, SoE was high for no increased risk of autism following measles, mumps, and rubella (MMR) vaccine. SoE was high for increased risk of febrile seizures with MMR. There was no evidence of increased risk of intussusception with rotavirus vaccine at the latest follow-up (moderate SoE), nor of diabetes (high SoE). There was no evidence of increased risk or insufficient evidence for key adverse events for newer vaccines such as 9-valent human papillomavirus and meningococcal B vaccines. For adults, there was no evidence of increased risk (varied SoE) or insufficient evidence for key adverse events for the new adjuvanted inactivated influenza vaccine and recombinant adjuvanted zoster vaccine. We found no evidence of increased risk (varied SoE) for key adverse events among pregnant women following tetanus, diphtheria, and acellular pertussis vaccine, including stillbirth (moderate SoE). CONCLUSIONS Across a large body of research we found few associations of vaccines and serious key adverse events; however, rare events are challenging to study. Any adverse events should be weighed against the protective benefits that vaccines provide.

Abstract
Rubella is a vaccine preventable infection, and congenital rubella the most feared complication of this disease. Although young adult women are at greatest risk of post-vaccine rubella, this is also the group who potentially benefits the most from vaccine protection. Since post-vaccine disease has a mild and self-limited course, the benefit clearly exceeds the risk. During a measles outbreak in the north of Portugal, a 38-year-old woman presented with cervical posterior lymphadenopathies, fever and a maculo-papular rash one week after the administration of the measles, mumps and rubella vaccine. Measles was discarded and rubella viremia was demonstrated. Symptoms of rubella are non-specific and laboratory confirmation is essential. This is particularly relevant during a measles outbreak.

Abstract
BACKGROUND Measles is a highly contagious and serious infection. Before the introduction of vaccination, measles caused yearly epidemics putting vulnerable children at risk of brain damage and death. Despite safe and cost-effective vaccines, measles remains a leading cause of death in children globally. Due to insufficient vaccine coverage and low levels of in utero transferred antibodies from vaccinated mothers, outbreaks of measles in Denmark and other high-income countries are observed at increasing frequency. The current vaccine was introduced in Denmark in 1987 as a one-shot measles-mumps-rubella vaccine at 15 months, a timing chosen to avoid inhibition of the infant's immune response by maternal antibodies. One generation later, the MMR vaccinated mothers have lower antibody levels compared to the naturally infected, and their infants are already susceptible at 6 months of age or earlier, thus increasing the risk of epidemics. METHODS The Danish MMR trial is a double-blind randomized clinical trial recruiting between March 2019 and December 2021 with last patient last visit in February 2022. Altogether N = 6500 infants aged 6 months will be randomly assigned to intramuscular vaccination with routine MMR (M-M-R VaxPro) or placebo (solvent only). According to the Danish Childhood vaccination program, all infants will receive a routine MMR vaccination at 15 months of age. At randomization, 1 month later, and 1 month after routine MMR vaccination at 15 months of age, a blood sample is drawn from app. 10% (N = 600) of the population. Additionally, hair, saliva, and urine are sampled at randomization. The co-primary study outcomes are immunogenicity 1 month after MMR vaccination at 6 months of age assessed as plaque-reduction neutralization test, and incidence of infectious disease hospitalizations from randomization to 12 months of age. Six weeks post randomization, all participants are interviewed regarding adverse events. TRIAL REGISTRATION The trial is registered in the EU Clinical Trials Registry. EudraCT registration number: 2016-001901-18 . Registered on 14 February 2017.

Abstract
Immunocompromised individuals are at increased risk of infectious diseases and their complications. The main examples of these are pneumococcal disease and influenza, infections that are both vaccine-preventable. However, responses to vaccination are often impaired in immunocompromised patients. In addition, live-attenuated vaccines, including the measles-mumps-rubella and yellow fever vaccine, cannot be administered to these patients for safety reasons. In view of the decreasing herd immunity caused by a drop in global vaccination coverage, immunocompromised individuals are at increased risk of infections such as measles, especially during travel abroad. Despite these developments, the improved quality of life resulting from novel treatment options means that immunocompromised patients are travelling more and further than ever. It is the responsibility of the treating physician of the immunocompromised individual to ensure that all the required vaccines are provided in time. To this end, the physician may also refer the patient to the general practitioner or travel clinic for the actual vaccination.

Abstract
Since 2006, some Italian Regions introduced the active offer of measles, mumps, rubella, and varicella (MMRV) vaccine for all newborns during the second years of life. In 2011, Italian Drug Authority (AIFA) recommended the discontinuation of the MMRV use for an increased risk of febrile seizures following vaccination; furthermore, some Regions (such as Apulia, that introduced MMRV offer in 2009) chose to continue the use of MMRV and Ministry of Health recommended to guarantee supplemental monitoring of safety of the vaccine. In Italy, the surveillance of Adverse Events following immunization (AEFIs) is currently carried out by AIFA and Regional Health Authorities; this paper aims to summarize the results of MMRV-vaccine surveillance of AEFIs program carried out in Apulia. From the AIFA database, we selected MMRV AEFIs that occurred in Apulia (about 4,000,000 inhabitants) from 2009 to 2017. For serious AEFIs, we applied the WHO causality assessment algorithm, using for cases hospitalized information from individual medical records. In the 8 years of observation, 155 MMRV-AEFIs (reporting rate: 37.9×100,000 doses) occurred of which 26 were classified as serious (6.3×100,000 doses) and 22 led to hospitalization. Performing causality assessment, for 10 the classification was "consistent causal association to immunization" (reporting rate: 2.4×100000 doses), for 2 indeterminate, for 13 "inconsistent causal association to immunization" and for 1 not-classifiable. No case of febrile seizure resulted consistent to vaccination. All consistent serious AEFIs were completely resolved at subsequent follow-up.

Abstract
BACKGROUND Measles, mumps, rubella, and varicella (chickenpox) are serious diseases that can lead to serious complications, disability, and death. However, public debate over the safety of the trivalent MMR vaccine and the resultant drop in vaccination coverage in several countries persists, despite its almost universal use and accepted effectiveness. This is an update of a review published in 2005 and updated in 2012. OBJECTIVES To assess the effectiveness, safety, and long- and short-term adverse effects associated with the trivalent vaccine, containing measles, rubella, mumps strains (MMR), or concurrent administration of MMR vaccine and varicella vaccine (MMR+V), or tetravalent vaccine containing measles, rubella, mumps, and varicella strains (MMRV), given to children aged up to 15 years. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2019, Issue 5), which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (1966 to 2 May 2019), Embase (1974 to 2 May 2019), the WHO International Clinical Trials Registry Platform (2 May 2019), and ClinicalTrials.gov (2 May 2019). SELECTION CRITERIA We included randomised controlled trials (RCTs), controlled clinical trials (CCTs), prospective and retrospective cohort studies (PCS/RCS), case-control studies (CCS), interrupted time-series (ITS) studies, case cross-over (CCO) studies, case-only ecological method (COEM) studies, self-controlled case series (SCCS) studies, person-time cohort (PTC) studies, and case-coverage design/screening methods (CCD/SM) studies, assessing any combined MMR or MMRV / MMR+V vaccine given in any dose, preparation or time schedule compared with no intervention or placebo, on healthy children up to 15 years of age. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the methodological quality of the included studies. We grouped studies for quantitative analysis according to study design, vaccine type (MMR, MMRV, MMR+V), virus strain, and study settings. Outcomes of interest were cases of measles, mumps, rubella, and varicella, and harms. Certainty of evidence of was rated using GRADE. MAIN RESULTS We included 138 studies (23,480,668 participants). Fifty-one studies (10,248,159 children) assessed vaccine effectiveness and 87 studies (13,232,509 children) assessed the association between vaccines and a variety of harms. We included 74 new studies to this 2019 version of the review. Effectiveness Vaccine effectiveness in preventing measles was 95% after one dose (relative risk (RR) 0.05, 95% CI 0.02 to 0.13; 7 cohort studies; 12,039 children; moderate certainty evidence) and 96% after two doses (RR 0.04, 95% CI 0.01 to 0.28; 5 cohort studies; 21,604 children; moderate certainty evidence). The effectiveness in preventing cases among household contacts or preventing transmission to others the children were in contact with after one dose was 81% (RR 0.19, 95% CI 0.04 to 0.89; 3 cohort studies; 151 children; low certainty evidence), after two doses 85% (RR 0.15, 95% CI 0.03 to 0.75; 3 cohort studies; 378 children; low certainty evidence), and after three doses was 96% (RR 0.04, 95% CI 0.01 to 0.23; 2 cohort studies; 151 children; low certainty evidence). The effectiveness (at least one dose) in preventing measles after exposure (post-exposure prophylaxis) was 74% (RR 0.26, 95% CI 0.14 to 0.50; 2 cohort studies; 283 children; low certainty evidence). The effectiveness of Jeryl Lynn containing MMR vaccine in preventing mumps was 72% after one dose (RR 0.24, 95% CI 0.08 to 0.76; 6 cohort studies; 9915 children; moderate certainty evidence), 86% after two doses (RR 0.12, 95% CI 0.04 to 0.35; 5 cohort studies; 7792 children; moderate certainty evidence). Effectiveness in preventing cases among household contacts was 74% (RR 0.26, 95% CI 0.13 to 0.49; 3 cohort studies; 1036 children; moderate certainty evidence). Vaccine effectiveness against rubella is 89% (RR 0.11, 95% CI 0.03 to 0.42; 1 cohort study; 1621 children; moderate certainty evidence). Vaccine effectiveness against varicella (any severity) after two doses in children aged 11 to 22 months is 95% in a 10 years follow-up (rate ratio (rr) 0.05, 95% CI 0.03 to 0.08; 1 RCT; 2279 children; high certainty evidence). Safety There is evidence supporting an association between aseptic meningitis and MMR vaccines containing Urabe and Leningrad-Zagreb mumps strains, but no evidence supporting this association for MMR vaccines containing Jeryl Lynn mumps strains (rr 1.30, 95% CI 0.66 to 2.56; low certainty evidence). The analyses provide evidence supporting an association between MMR/MMR+V/MMRV vaccines (Jeryl Lynn strain) and febrile seizures. Febrile seizures normally occur in 2% to 4% of healthy children at least once before the age of 5. The attributable risk febrile seizures vaccine-induced is estimated to be from 1 per 1700 to 1 per 1150 administered doses. The analyses provide evidence supporting an association between MMR vaccination and idiopathic thrombocytopaenic purpura (ITP). However, the risk of ITP after vaccination is smaller than after natural infection with these viruses. Natural infection of ITP occur in 5 cases per 100,000 (1 case per 20,000) per year. The attributable risk is estimated about 1 case of ITP per 40,000 administered MMR doses. There is no evidence of an association between MMR immunisation and encephalitis or encephalopathy (rate ratio 0.90, 95% CI 0.50 to 1.61; 2 observational studies; 1,071,088 children; low certainty evidence), and autistic spectrum disorders (rate ratio 0.93, 95% CI 0.85 to 1.01; 2 observational studies; 1,194,764 children; moderate certainty). There is insufficient evidence to determine the association between MMR immunisation and inflammatory bowel disease (odds ratio 1.42, 95% CI 0.93 to 2.16; 3 observational studies; 409 cases and 1416 controls; moderate certainty evidence). Additionally, there is no evidence supporting an association between MMR immunisation and cognitive delay, type 1 diabetes, asthma, dermatitis/eczema, hay fever, leukaemia, multiple sclerosis, gait disturbance, and bacterial or viral infections. AUTHORS' CONCLUSIONS Existing evidence on the safety and effectiveness of MMR/MMRV vaccines support their use for mass immunisation. Campaigns aimed at global eradication should assess epidemiological and socioeconomic situations of the countries as well as the capacity to achieve high vaccination coverage. More evidence is needed to assess whether the protective effect of MMR/MMRV could wane with time since immunisation.

Abstract
Since Wakefield et al. (1998), the public was exposed to mixed information surrounding the claim that measles-mumps-rubella vaccine causes autism. A persistent trend to delay the vaccination during 1998-2011 in the US was driven by children of college-educated mothers, suggesting that these mothers held biases against the vaccine influenced by the early unfounded claim. Consistent with confirmatory bias, exposures to negative information about the vaccine strengthened their biases more than exposures to positive information attenuated them. Positive online information, however, had strong impacts on vaccination decisions, suggesting that online dissemination of vaccine-safety information may help tackle the sticky misinformation.

Abstract
BACKGROUND Despite the significant role played by vaccines in global health, concerns over vaccine safety have increased tremendously over the years. There have been occasions where vaccines have caused rare, adverse reactions some of which have led to hospitalizations and even death. It is therefore important to establish the safety profile of routinely used vaccines in order to allay fears pertaining to their use. OBJECTIVES This review was aimed at pooling together the safety data of selected vaccines used for routine immunization in Africa, a region of the world with paucity of vaccine safety data. METHODS Adverse Events Following Immunization safety data was searched for rotavirus, yellow fever, measles, rubella, tuberculosis (Bacillus Calmette Guerin-BCG), pneumococcal, Haemophilus Influenza type b, polio, meningococcal and the influenza A (H1N1) vaccines in PUBMED, Google Scholar, Clinical trials.gov and Cochrane controlled register of trials databases. RESULTS A total of twenty-four serious AEFIs and twenty-three minor AEFIs were identified from the review. The strength of association between AEFIs and vaccine was high for tuberculosis vaccine and moderate for all other vaccines. CONCLUSION Even though AEFIs (including mild and severe) were identified in the review, all the vaccines studied were generally well tolerated.

Abstract
Measles is a highly infectious viral illness and is one of the world's most contagious diseases that can affect all people if they have not been vaccinated or have not had it before. Before measles vaccine became available in 1963, major epidemic occurred approximately every 2 to 3 years and thus 99% of the people were thought to have been infected naturally with measles virus and got immune for life. In 2000, measles was declared eliminated from the United States, and yet 1215 cases have been reported from 30 states as of August 22, 2019. Currently, there are several large measles outbreaks universally, and some people who were not immune and they need to get their measles, mumps, rubella (MMR) vaccine to prevent measles outbreaks. As vaccination coverage increases, the average age of measles infection can change to adolescents and young adults. In addition, the protective antibodies derived from vaccination might decrease gradually, and the risk of measles infection in young adults is increasing regardless of international travelling.

Abstract
Rubella viruses (RV) have been found in an association with granulomas in children with primary immune deficiencies (PID). Here, we report the recovery and characterization of infectious immunodeficiency-related vaccine-derived rubella viruses (iVDRV) from diagnostic skin biopsies of four patients. Sequence evolution within PID hosts was studied by comparison of the complete genomic sequences of the iVDRVs with the genome of the vaccine virus RA27/3. The degree of divergence of each iVDRV correlated with the duration of persistence indicating continuous intrahost evolution. The evolution rates for synonymous and nonsynonymous substitutions were estimated to be 5.7 x 10-3 subs/site/year and 8.9 x 10-4 subs/site/year, respectively. Mutational spectra and signatures indicated a major role for APOBEC cytidine deaminases and a secondary role for ADAR adenosine deaminases in generating diversity of iVDRVs. The distributions of mutations across the genes and 3D hotspots for amino acid substitutions in the E1 glycoprotein identified regions that may be under positive selective pressure. Quasispecies diversity was higher in granulomas than in recovered infectious iVDRVs. Growth properties of iVDRVs were assessed in WI-38 fibroblast cultures. None of the iVDRV isolates showed complete reversion to wild type phenotype but the replicative and persistence characteristics of iVDRVs were different from those of the RA27/3 vaccine strain, making predictions of iVDRV transmissibility and teratogenicity difficult. However, detection of iVDRV RNA in nasopharyngeal specimen and poor neutralization of some iVDRV strains by sera from vaccinated persons suggests possible public health risks associated with iVDRV carriers. Detection of IgM antibody to RV in sera of two out of three patients may be a marker of virus persistence, potentially useful for identifying patients with iVDRV before development of lesions. Studies of the evolutionary dynamics of iVDRV during persistence will contribute to development of infection control strategies and antiviral therapies.

Abstract
OBJECTIVES To estimate the association between childhood vaccination and subsequent morbidity and mortality by adjusting for environmental and host factors. Further, to examine the degree of residual confounding in such observational studies. DESIGN Register-based cohort study including 1 122 929 Danish children. PARTICIPANTS All children born in Denmark in the period 1999-2016 who survived until 16 months of age without prior migration followed from 16 months until the first of the following: event of interest, migration, 5 years of age or 31 December 2016. MAIN OUTCOME MEASURES Adjusted HRs (aHRs) and absolute risks were calculated for the three outcomes: mortality, hospitalisation for infection and asthma using register data on deaths, specific hospital contacts and dispensed prescribed medication. The exposure was the combination of the routine vaccines against diphteria-tetanus-pertussis-polio-Haemophilus influenzae type b and measles-mumps-rubella (DTP and MMR in short) administered in early childhood. Hospitalisation due to accidents was analysed as a negative control outcome to examine residual confounding. RESULTS Children with 3DTP+MMR had a lower hazard of mortality than the reference group with 3DTP, adjusted HR (aHR)=0.45 (95% CI: 0.35 to 0.57), whereas the children with 1 or 2 DTP had higher hazards of dying, aHR=1.55 (95% CI: 1.14 to 2.13) and aHR=1.96 (95% CI: 1.34 to 2.89). The vaccination group 3DTP+MMR was associated with a reduced hazard of asthma aHR=0.94 (95% CI: 0.92 to 0.96). Also, the vaccination group 3DTP+MMR was associated with a reduced hazard of hospitalisation due to accidents, aHR=0.83 (0.80 to 0.85) compared with the reference group with 3 DTP. CONCLUSIONS The results suggested a beneficial impact of MMR on under-five mortality but did not support the hypothesis that DTP is detrimental, since the group of children with fewer DTP vaccinations experienced increased mortality. The results of the study may to some degree be prone to residual confounding since an unexpected association between MMR vaccination and hospitalisation for accidents was observed.

Abstract
RATIONALE Seizures are rare during the perioperative period; in most cases, there is a previous history of epilepsy or surgery-associated seizures. Febrile convulsions may occur when the body temperature rises above 38°C; this is the most common cause of seizures in children. Febrile convulsions after general anesthesia in the postanesthetic care unit (PACU) without a past or family history are rare. Some reviews suggest that since anesthesia changes immunity, elective surgery should be postponed three weeks after live vaccination. PATIENT A 12-month-old female with bilateral hearing loss underwent cochlear implantation under general anesthesia. She did not have any history of convulsions or developmental disorders. However, 1 week before surgery, measles-mumps-rubella (MMR) vaccination was given as a regular immunization. DIAGNOSES Forty minutes after arrival at the PACU, sudden generalized tonic-clonic movement occurred during recovery and the patient's measured body temperature exceeded 38.0°C. INTERVENTIONS Thiopental sodium was administered intravenously as an anticonvulsant, and the tonic-clonic movement stopped immediately. Endotracheal intubation was performed to secure the airway, and tepid massage and diclofenac β-dimethylaminoethanol administration were performed to lower the patient's body temperature. OUTCOMES There was no further fever and no seizures, and no other neurological deficits were observed until discharge. LESSONS The anesthesiologist should check the recent vaccination history even if the patient has not developed particular symptoms after vaccination. It is important to know that febrile convulsions may occur in patients who have recently received MMR vaccination.

Abstract
OBJECTIVE To systematically review literature on uptake and timeliness of diphtheria-tetanus-pertussis, measles-mumps-rubella, and/or polio-containing vaccines ininfants who were born preterm, with a low birth weight, and/or with chronic health conditions that were diagnosed within the first 6 months of life. METHODS Using a standardized search strategy developed by a medical librarian, records were extracted from MEDLINE, Embase, Database of Abstracts of Reviews of Effects, and CINAHL up to May 8, 2018. RESULTS Out of the 1997 records that were screened, we identified 21 studies that met inclusion criteria. Eleven studies assessed vaccine coverage and/or timeliness in preterm infants, 6 in low birth weight infants, and 7 in children with chronic health conditions. Estimates of coverage in these populations were highly variable, ranging from 40% to 100% across the vaccines and population groups. CONCLUSIONS There is a lack of studies reporting coverage and timeliness of routine immunizations in special populations of children. POLICY IMPLICATIONS Our review suggests a need for improved surveillance of immunization status in special populations of infants, as wellas aneed for standardization of reporting practices.

Abstract
Acute disseminated encephalomyelitis is a rare inflammatory demyelinating multifocal disease of the central nervous system that typically occurs in children following vaccination or exanthematous viral infections and conveys an elevated risk of neurological sequelae unless promptly recognized and treated. We describe an adult case of acute disseminated encephalomyelitis following vaccination against Mumps, Measles and Rubella, presenting with fever and progressive neurological deficits which improved under systemic corticosteroid therapy. Considering the ongoing public debate regarding universal vaccination and the surge of previously controlled infectious diseases, we aim not only to underline the need for a rigorous assessment of vaccination safety on adult patients in order to prevent misguidance of public opinion, but also to alert clinicians for an early diagnosis of acute disseminated encephalomyelitis in these patients, the incidence of which we speculate may be rising.

Abstract
In the wake of strong, although later refuted, claims of a link between autism and the measles-mumps-rubella (MMR) vaccine, I examine whether fewer parents immunized or delayed vaccinations for their children and if there was a differential response by mother's education level. Using various controls and a differencing strategy that compares in MMR take-up with other vaccines, I find that the MMR-autism controversy led to a decline in the immediate years and that there were negative spillovers onto other vaccines. I also find evidence that more highly educated mothers responded more strongly to the controversy either by not immunizing their children altogether or, to a lesser degree, delaying vaccination. Moreover, the educational gap was greater in states where there was greater media attention devoted to the controversy. This is consistent with the health allocative efficiency hypothesis whereby part of the education gradient in health outcomes is due to more-educated individuals absorbing and responding to health information more quickly. However, unlike in the United Kingdom, where previous studies find that the gap was eliminated after the link was refuted, the evidence for the United States suggests that the educational gap persisted.

Abstract
Human immunodeficiency virus (HIV) causes immune dysregulation, potentially affecting response to vaccines in infected persons. We investigated if unexpected adverse events (AEs) or unusual patterns of AEs after vaccination were reported among HIV-positive persons. We searched for domestic reports among HIV-positive persons to the Vaccine Adverse Event Reporting System (VAERS) during 1990–2016. We analyzed reports by age group (<19 and ≥19 years), sex, serious or non-serious status, live vaccine type (live versus inactivated), AEs reported, and CD4 counts. Of 532,235 reports received, 353 (0.07%) described HIV-positive persons, of whom 67% were aged ≥19 years, and 57% were male; most reports (75%) were non-serious. The most commonly reported inactivated vaccines were pneumococcal polysaccharide (27%) and inactivated influenza (27%); the mostly reported common live virus vaccines were combination measles, mumps, and rubella (8%) and varicella (6%). Injection site reactions were commonly reported (39%). Of 67 reports with CD4 counts available, 41 (61%) described persons immunocompromised at time of vaccination (CD4 count <500 cells/mm3), and differed from overall reports only in that varicella was the most common live virus vaccine (4 reports). Of 22 reports describing failure to protect against infection, 6 described persons immunocompromised at time of vaccination, among whom varicella vaccine was most common (3 reports). Of 66 reports describing live virus vaccines, 7 described persons with disseminated infection: 6 had disseminated varicella, 3 of whom had vaccine strain varicella-zoster virus. Of 18 reported deaths, 7 resulted from disseminated infection: 6 were among immunocompromised persons, 1 of whom had vaccine strain varicella-zoster virus. We identified no unexpected or unusual patterns of AEs among HIV-positive persons. These data reinforce current vaccine recommendations for this risk group. However, healthcare providers should know their HIV-positive patients’ immune status because immunocompromising conditions can potentially increase the risk of rare, but severe, AEs following vaccination with live virus vaccines.

Abstract
PURPOSE The risk of post-vaccination adverse events (AEs) is a primary public health concern. Among the AEs, pain is a significant source of anxiety for both children and their parents. This review describes and assesses the intensity of pain experienced by children post-vaccination with widely used Measles-Mumps-Rubella (MMR) vaccines. METHODS A systematic literature search was conducted in Pubmed, Embase and Cochrane to identify publications describing immediate pain at injection site (primary objective) or pain within days (secondary objective) after 2 specific MMR vaccines. Immediate pain ('acute pain' according to the Brighton Collaboration case definition) was defined as pain occurring at the time or within 5min of injection. RESULTS Four studies, which compared the intensity of immediate injection site pain experienced by children after MMR vaccination, were identified. Various pain assessment tools and methods were used to quantify the intensity of pain, including the median difference in Visual Analog Scale scores between vaccine groups. All four studies showed significantly less immediate pain caused by Priorix (GSK Vaccines) compared with M-M-R II (Merck & Co., Inc.). CONCLUSIONS To our knowledge, this review summarizes for the first time the available scientific evidence on the intensity of pain following different MMR vaccines. It highlights that MMR vaccines can differ in terms of immediate pain. Further research may be needed to better understand the underlying reason for this observation. In this context, it is very important to understand which physicochemical properties are most relevant for the immediate pain profile of a vaccine to thereby support the development of vaccines with the best possible immediate pain profile.

Abstract
MMR vaccination in 6-9 month olds Vaccination against measles using the MMR vaccine is licensed from 9 months of age, but is used off-label from 6 months of age during or when travelling to areas with an ongoing measles outbreak. In this review of the published literature, studies on MMR vaccination in this age group are limited and small in size. Immunogenicity studies indicate that infants under 9 months respond with lower antibody titres but comparable T cell responses against measles. The safety profile of the vaccine does not appear to differ between infants vaccinated earlier or later. Vaccination from 6 months of age should be recommended if the risk of being infected with measles is considered greater than the risk of not attaining full vaccination protection.

Abstract
Vaccines are one of the most successful medical advances in modern times. Most vaccine-preventable illnesses are unfamiliar to modern parents. Because of this, parents are increasingly questioning the necessity of immunizing their children, especially because no vaccine is completely free of adverse effects or the risk of complications. Family physicians should be aware of the risks and benefits of recommended immunizations. Thimerosal is currently used only in multidose vials of influenza vaccine, and exposure through vaccines is not associated with adverse neurologic outcomes. The measles, mumps, and rubella vaccine is not associated with autism. Vaccines are associated with local reactions, such as pain and erythema. The rotavirus vaccine minimally increases the rate of intussusception, whereas other vaccines minimally increase the risk of syncope. Although immunization with the human papillomavirus vaccine is recommended for all boys and girls, vaccination rates remain low. Physicians should guide parents to credible resources if they are considering vaccine refusal. If a recommended vaccine is refused, proper documentation is essential. The Vaccine Adverse Event Reporting System and National Vaccine Injury Compensation Program track adverse events and allow compensation for documented harms from vaccinations.

Abstract
Question Parents of a 12-month-old boy are bringing their son in to my family practice clinic for his well-baby visit. As the infant is due for his 12-month vaccine series, the parents are concerned after hearing about the association between certain vaccinations and an increased risk of febrile seizures, and are wondering if they should administer prophylactic antipyretics to decrease the risk of febrile seizure. What vaccinations are associated with increased risk of febrile seizure, and is there evidence supporting prophylactic administration of antipyretics to prevent febrile seizures? Answer Vaccinations associated with increased risk of febrile seizure include the following: the measles-mumps-rubella vaccine; the measles-mumps-rubella-varicella vaccine; the combined diphtheria, tetanus, acellular pertussis, polio, and Haemophilus influenzae type b vaccine; the whole-cell pertussis vaccine; the 7-valent pneumococcal conjugate vaccine; and concomitant administration of the trivalent inactivated influenza vaccine with either the 7-valent pneumococcal conjugate vaccine or the diphtheria, tetanus, and acellular pertussis vaccine. Despite being a higher-risk group, children receiving these vaccinations should not receive prophylactic antipyretics, as no statistically significant reduction in the rate of febrile seizures has been documented, and prophylactic antipyretic use potentially decreases the immune response to certain vaccines.

Abstract
Clinical adverse experience (AE) data are routinely evaluated using between group P values for every AE encountered within each of several body systems. If the P values are reported and interpreted without multiplicity considerations, there is a potential for an excess of false positive findings. Procedures based on confidence interval estimates of treatment effects have the same potential for false positive findings as P value methods. Excess false positive findings can needlessly complicate the safety profile of a safe drug or vaccine. Accordingly, we propose a novel method for addressing multiplicity in the evaluation of adverse experience data arising in clinical trial settings. The method involves a two-step application of adjusted P values based on the Benjamini and Hochberg1 false discovery rate (FDR). Data from three moderate to large vaccine trials are used to illustrate our proposed ‘Double FDR’ approach, and to reinforce the potential impact of failing to account for multiplicity. This work was in collaboration with the late Professor John W. Tukey who coined the term ‘Double FDR’.
