Abstract
This report compiles and summarizes all published recommendations from CDC’s Advisory Committee on Immunization Practices (ACIP) for use of pneumococcal vaccines in adults aged ≥19 years in the United States. This report also includes updated and new clinical guidance for implementation from CDC Before 2021, ACIP recommended 23-valent pneumococcal polysaccharide vaccine (PPSV23) alone (up to 2 doses), or both a single dose of 13-valent pneumococcal conjugate vaccine (PCV13) in combination with 1–3 doses of PPSV23 in series (PCV13 followed by PPSV23), for use in U.S. adults depending on age and underlying risk for pneumococcal disease. In 2021, two new pneumococcal conjugate vaccines (PCVs), a 15-valent and a 20-valent PCV (PCV15 and PCV20), were licensed for use in U.S. adults aged ≥18 years by the Food and Drug Administration ACIP recommendations specify the use of either PCV20 alone or PCV15 in series with PPSV23 for all adults aged ≥65 years and for adults aged 19–64 years with certain underlying medical conditions or other risk factors who have not received a PCV or whose vaccination history is unknown. In addition, ACIP recommends use of either a single dose of PCV20 or ≥1 dose of PPSV23 for adults who have started their pneumococcal vaccine series with PCV13 but have not received all recommended PPSV23 doses. Shared clinical decision-making is recommended regarding use of a supplemental PCV20 dose for adults aged ≥65 years who have completed their recommended vaccine series with both PCV13 and PPSV23 Updated and new clinical guidance for implementation from CDC includes the recommendation for use of PCV15 or PCV20 for adults who have received PPSV23 but have not received any PCV dose. The report also includes clinical guidance for adults who have received 7-valent PCV (PCV7) only and adults who are hematopoietic stem cell transplant recipients

Abstract
The International Symposium on Pneumococci and Pneumococcal Diseases (ISPPD) is the premier global scientific symposium dedicated to the exchange, advancement and dissemination of the latest research on the pneumococcus, one of the world's deadliest bacterial pathogens. Since the first ISPPD was held in 1998, substantial progress has been made to control pneumococcal disease, for instance, more than half of surviving infants (78.6 million) from 143 countries now have access to the life-saving pneumococcal conjugate vaccine (PCV). The 11th ISPPD (ISPPD-11) was held in Melbourne, Australia in April 2018 and the proceedings of the symposium are captured in this report. Twenty years on from the first ISPPD, there remain many challenges and unanswered questions such as the continued disparity in disease incidence in Indigenous populations, the slow roll-out of PCV in some regions such as Asia, the persisting burden of disease in adults, serotype replacement and diagnosis of pneumococcal pneumonia. ISPPD-11 also put the spotlight on cutting-edge science including metagenomic, transcriptomic, microscopy, medical imaging and mathematical modelling approaches. ISPPD-11 was highly diverse, bringing together 1184 delegates from 86 countries, representing various fields including academia, primary healthcare, pharmaceuticals, biotechnology, policymakers and public health.

Abstract
Pneumonia is the leading cause of morbidity and mortality, particularly in old adults. The incidence and etiologic distribution of community-acquired pneumonia is variable both geographically and temporally, and epidemiology might evolve with the change of population characteristics and vaccine uptake rates. With the increasing prevalence of chronic medical conditions, a wide spectrum of healthcare-associated pneumonia could also affect the epidemiology of community-acquired pneumonia. Here, we provide an overview of the epidemiological changes associated with community-acquired pneumonia over the decades since pneumococcal conjugate vaccine introduction.

Abstract
BACKGROUND Streptococcus pneumoniae is capable of causing multiple infectious syndromes and occasionally causes outbreaks. The objective of this review is to update prior outbreak reviews, identify control measures, and comment on transmission. METHODS We conducted a review of published S. pneumoniae outbreaks, defined as at least two linked cases of S. pneumoniae. RESULTS A total of 98 articles (86 respiratory; 8 conjunctivitis; 2 otitis media; 1 surgical site; 1 multiple), detailing 94 unique outbreaks occurring between 1916 to 2017 were identified. Reported serotypes included 1, 2, 3, 4, 5, 7F, 8, 12F, 14, 20, and 23F, and serogroups 6, 9, 15, 19, 22. The median attack rate for pneumococcal outbreaks was 7.0% (Interquartile range: 2.4%, 13%). The median case-fatality ratio was 12.9% (interquartile range: 0%, 29.2%). Age groups most affected by outbreaks were older adults (60.3%) and young adults (34.2%). Outbreaks occurred in crowded settings, such as universities/schools/daycares, military barracks, hospital wards, and long-term care facilities. Of outbreaks that assessed vaccination coverage, low initial vaccination or revaccination coverage was common. Most (73.1%) of reported outbreaks reported non-susceptibility to at least one antibiotic, with non-susceptibility to penicillin (56.0%) and erythromycin (52.6%) being common. Evidence suggests transmission in outbreaks can occur through multiple modes, including carriers, infected individuals, or medical devices. Several cases developed disease shortly after exposure (< 72 h). Respiratory outbreaks used infection prevention (55.6%), prophylactic vaccination (63.5%), and prophylactic antibiotics (50.5%) to prevent future cases. PPSV23 covered all reported outbreak serotypes. PCV13 covered 10 of 16 serotypes. For conjunctival outbreaks, only infection prevention strategies were used. CONCLUSIONS To prevent the initial occurrence of respiratory outbreaks, vaccination and revaccination is likely the best preventive measure. Once an outbreak occurs, vaccination and infection-prevention strategies should be utilized. Antibiotic prophylaxis may be considered for high-risk exposed individuals, but development of antibiotic resistance during outbreaks has been reported. The short period between initial exposure and development of disease indicates that pneumococcal colonization is not a prerequisite for pneumococcal respiratory infection.

Abstract
BACKGROUND Although a considerable amount is known about the effect of age on the manifestations and outcomes of pneumonia, the same is not true for invasive pneumococcal disease. METHODS This was a prospective observational study of all cases (2435) of invasive pneumococcal disease in adults in Northern Alberta from 2000 to 2014. Rates of invasive pneumococcal disease per 100,000, sociodemographic variables, clinical characteristics, and invasive pneumococcal disease-related outcomes were compared for the following age groups: 17-54, 55-64, 65-74, and ≥75 years. RESULTS The rate of invasive pneumococcal disease per 100,000 increased with increasing age. Although only 27.3% of the cases were in those aged ≥65 years, they accounted for 48% of the deaths. The case fatality rate increased with increasing age, from 9.6% for those aged 17-54 years to 31.7% for those aged ≥75 years. The rate of meningitis decreased with increasing age, as did admission to intensive care and use of mechanical ventilation. There was a marked reduction in the rate of invasive pneumococcal disease due to protein conjugate vaccine 7 and protein conjugate vaccine 13 serotypes in those aged ≥55 years but a much smaller decline in rates for those aged 17-54 years. Replacement with non-vaccine serotypes constituted approximately 50% of the cases. CONCLUSIONS The rate of invasive pneumococcal disease is highest in the very elderly, and manifestations of invasive pneumococcal disease are influenced by age.

Abstract
Efforts at preventing pneumococcal disease are a national health priority, particularly in older adults and especially in post-acute and long-term care settings The Advisory Committee on Immunization Practices recommends that all adults ≥65 years of age, as well as adults 18-64 years of age with specific risk factors, receive both the recently introduced polysaccharide-protein conjugate vaccine against 13 pneumococcal serotypes as well as the polysaccharide vaccine against 23 pneumococcal serotypes. Nursing facility licensure regulations require facilities to assess the pneumococcal vaccination status of each resident, provide education regarding pneumococcal vaccination, and administer the appropriate pneumococcal vaccine when indicated. Sorting out the indications and timing for 13 pneumococcal serotypes and 23 pneumococcal serotypes administration is complex and presents a significant challenge to healthcare providers. Here, we discuss the importance of pneumococcal vaccination for older adults, detail AMDA-The Society for Post-Acute and Long-Term Care Medicine (The Society)'s recommendations for pneumococcal vaccination practice and procedures, and offer guidance to postacute and long-term care providers supporting the development and effective implementation of pneumococcal vaccine policies.

Abstract
BACKGROUND An outbreak of pneumococcal meningitis among non-infant children and adults occurred in the Brong-Ahafo region of Ghana between December 2015 and April 2016 despite the recent nationwide implementation of a vaccination programme for infants with the 13-valent pneumococcal conjugate vaccine (PCV13). METHODS Cerebrospinal fluid (CSF) specimens were collected from patients with suspected meningitis in the Brong-Ahafo region. CSF specimens were subjected to Gram staining, culture and rapid antigen testing. Quantitative PCR was performed to identify pneumococcus, meningococcus and Haemophilus influenzae. Latex agglutination and molecular serotyping were performed on samples. Antibiogram and whole genome sequencing were performed on pneumococcal isolates. RESULTS Eight hundred eighty six patients were reported with suspected meningitis in the Brong-Ahafo region during the period of the outbreak. In the epicenter district, the prevalence was as high as 363 suspected cases per 100,000 people. Over 95 % of suspected cases occurred in non-infant children and adults, with a median age of 20 years. Bacterial meningitis was confirmed in just under a quarter of CSF specimens tested. Pneumococcus, meningococcus and Group B Streptococcus accounted for 77 %, 22 % and 1 % of confirmed cases respectively. The vast majority of serotyped pneumococci (80 %) belonged to serotype 1. Most of the pneumococcal isolates tested were susceptible to a broad range of antibiotics, with the exception of two pneumococcal serotype 1 strains that were resistant to both penicillin and trimethoprim-sulfamethoxazole. All sequenced pneumococcal serotype 1 strains belong to Sequence Type (ST) 303 in the hypervirulent ST217 clonal complex. CONCLUSION The occurrence of a pneumococcal serotype 1 meningitis outbreak three years after the introduction of PCV13 is alarming and calls for strengthening of meningitis surveillance and a re-evaluation of the current vaccination programme in high risk countries.

Abstract
Because cord blood (CB) lacks memory T and B cells and recent decreases in herd immunity to vaccine-preventable diseases in many developed countries have been documented, vaccine responses in CB transplantation (CBT) survivors are of great interest. We analyzed vaccine responses in double-unit CBT recipients transplanted for hematologic malignancies. In 103 vaccine-eligible patients, graft-versus-host disease (GVHD) most commonly precluded vaccination. Sixty-five patients (63%; engrafting units median HLA-allele match 5/8; range, 2 to 7/8) received protein conjugated vaccines, and 63 patients (median age, 34 years; range, .9 to 64) were evaluated for responses. Median vaccination time was 17 months (range, 7 to 45) post-CBT. GVHD (n = 42) and prior rituximab (n = 13) delayed vaccination. Responses to Prevnar 7 and/or 13 vaccines (serotypes 14, 19F, 23F) were seen in children and adults (60% versus 49%, P = .555). Responses to tetanus, diphtheria, pertussis, Haemophilus influenzae, and polio were observed in children (86% to 100%) and adults (53% to 89%) even if patients had prior GVHD or rituximab. CD4(+)CD45RA(+) and CD19(+) cell recovery significantly influenced tetanus and polio responses. In a smaller cohort responses were seen to measles (65%), mumps (50%), and rubella (100%) vaccines. No vaccine side effects were identified, and all vaccinated patients survived (median follow-up, 57 months). Although GVHD and rituximab can delay vaccination, CBT recipients (including adults and those with prior GVHD) have similar vaccine response rates to adult donor allograft recipients supporting vaccination in CBT recipients.

Abstract
This clone has persisted in a post–acute care facility for >5 years. Prolonged outbreaks of multidrug-resistant Streptococcus pneumoniae in health care facilities are uncommon. We found persistent transmission of a fluroquinolone-resistant S. pneumoniae clone during 2006–2011 in a post–acute care facility in Israel, despite mandatory vaccination and fluoroquinolone restriction. Capsular switch and multiple antimicrobial nonsusceptibility mutations occurred within this single clone. The persistent transmission of fluoroquinolone-resistant S. pneumoniae during a 5-year period underscores the importance of long-term care facilities as potential reservoirs of multidrug-resistant streptococci.

Abstract
In August 2012, an explosive outbreak of severe lower respiratory tract infection (LRTI) due to Streptococcus pneumoniae serotype-8 occurred in a highly vaccinated elderly institutionalized population in England. Fifteen of 23 residents developed LRTI over 4 days (attack rate 65%); 11 had confirmed S. pneumoniae serotype-8 disease, and two died. Following amoxicillin chemoprophylaxis and pneumococcal polysaccharide vaccine (PPV) re-vaccination no further cases occurred in the following 2 months. No association was found between being an outbreak-associated case and age (P = 0.36), underlying comorbidities [relative risk (RR) 0.84 95% confidence interval (CI) 0.34-2.09], or prior receipt of PPV (RR 1.4, 95% CI 0.60-3.33). However, the median number of years since PPV was significantly higher for cases (n = 15, 10.2 years, range 7.3-17.9 years) than non-cases (n = 8, 7.2 years, range 6.8-12.8 years) (P = 0.045), provided evidence of waning immunity. Alternative vaccination strategies should be considered to prevent future S. pneumoniae outbreaks in institutionalized elderly populations.

Abstract
Although theoretically attractive, the reversibility of resistance has proven difficult in practice, even though antibiotic resistance mechanisms induce a fitness cost to the bacterium. Associated resistance to other antibiotics and compensatory mutations seem to ameliorate the effect of antibiotic interventions in the community. In this paper the current understanding of the concepts of reversibility of antibiotic resistance and the interventions performed in hospitals and in the community are reviewed.

Abstract
This is a report of an outbreak of Pneumococcal pneumonia among nursing home residents in Tokyo, 2009. A total of 15 cases were identified, and their sputum culture grew Streptococcus pneumoniae, all of which were confirmed as serotype 11A and ST116. This outbreak ended through the implementation of strict contact precautions, education regarding the standard precautions among the staff, administration of prophylactic antibiotics to other asymptomatic residents, and vaccination. The fact that many cases were unvaccinated in this outbreak implies the importance of vaccination against S. pneumoniae among nursing home residents.

Abstract
INTRODUCTION Older adults living in nursing homes (NH) are at high risk of developing influenza and pneumococcal infections. The objectives of this study were to describe vaccination coverage for influenza and pneumococcal among French NH residents and to investigate which NH structure- and organisation-related aspects could impact on vaccination in this population. METHODS This study is based on cross-sectional data from 175 French NHs (N=6275 residents), collected in May-July 2011. Residents' vaccination status (yes vs. no) against pneumococcal infection and seasonal influenza was recorded by the NH staff (on the basis of the resident's medical chart). Residents' health-related variables (e.g., co-morbidities) and information on NH structure and internal organisation were recorded by the NH staff. Mixed-effects logistic regressions were performed on influenza and pneumococcal vaccination separately. RESULTS Influenza vaccination coverage was high (n=5071, i.e., 80.8% of residents) and relatively well-distributed across NHs, whereas pneumococcal vaccination was low (n=1758, i.e., 28%) and highly variable across facilities. Mixed-effects logistic regressions confirmed that structural and organisational aspects related to the NH functioning impacted vaccination coverage. More precisely, living in a private for profit NH, living in NHs located in low-urban areas, and coordinating physician training increased the odds of receiving pneumococcal vaccine, whereas living in NHs located at high-urban areas decreased this odds. Moreover, the time spent by the coordinating physician in the NH increased the odds of receiving influenza vaccine. Prescriptions re-examination since resident's admission at the NH and the presence of an individualised health care project increased the odds of receiving both influenza and pneumococcal vaccines. CONCLUSIONS Our findings suggest that a more standardised approach is needed to improve vaccination coverage against pneumococcal infection in French NH residents.

Abstract
The benefits of vaccination in older adults are well documented yet there is poor uptake of such preventive measures, and one of the main reasons in France is a lack of recommendation and support from healthcare professionals. To address this issue a multidisciplinary group of experts has developed an educational tool, Vaxisenior, to assist in the training of physicians/healthcare workers who can act as advocates for immunization programs. The tool comprises of eight sections (general introduction; immunosenescence; diphtheria-tetanus-poliomyelitis; influenza; pneumococcus; pertussis; herpes zoster; and vaccines for travelers). In addition, it includes national immunization schedules and recommendations, practical information regarding opportunities to expand vaccine coverage that is convenient to the patient and a questions and answers section covering topics relating to particular usage and responsibilities. Implementation of vaccination policies for older adults is a major issue and will require extensive promotional campaigns, as well as active support from healthcare and public health professionals to improve overall vaccine coverage.

Abstract
OBJECTIVE To determine the efficacy of a 23-valent pneumococcal polysaccharide vaccine in people at high risk of pneumococcal pneumonia. DESIGN Prospective, randomised, placebo controlled double blind study. SETTING Nursing homes in Japan. PARTICIPANTS 1006 nursing home residents. INTERVENTIONS Participants were randomly allocated to either 23-valent pneumococcal polysaccharide vaccine (n=502) or placebo (n=504). MAIN OUTCOME MEASURES The primary end points were the incidence of all cause pneumonia and pneumococcal pneumonia. Secondary end points were deaths from pneumococcal pneumonia, all cause pneumonia, and other causes. RESULTS Pneumonia occurred in 63 (12.5%) participants in the vaccine group and 104 (20.6%) in the placebo group. Pneumococcal pneumonia was diagnosed in 14 (2.8%) participants in the vaccine group and 37 (7.3%) in the placebo group (P<0.001). All cause pneumonia and pneumococcal pneumonia were significantly more frequent in the placebo group than in the vaccine group: incidence per 1000 person years 55 v 91 (P<0.0006) and 12 v 32 (P<0.001), respectively. Death from pneumococcal pneumonia was significantly higher in the placebo group than in the vaccine group (35.1% (13/37) v 0% (0/14), P<0.01). The death rate from all cause pneumonia (vaccine group 20.6% (13/63) v placebo group 25.0% (26/104), P=0.5) and from other causes (vaccine group 17.7% (89/502) v placebo group (80/504) 15.9%, P=0.4) did not differ between the two study groups. CONCLUSION The 23-valent pneumococcal polysaccharide vaccine prevented pneumococcal pneumonia and reduced mortality from pneumococcal pneumonia in nursing home residents.

Abstract
Prevention is an important but neglected issue in geriatric medicine. Vaccination plays a major role in prevention of infectious diseases, but its implementation in clinical practice is far from perfect. To improve practice, a group of French experts composed of geriatricians and infectious disease specialists prepared a set of educational material about vaccination for older subjects. The tool has been designed to be used by medical teachers to help them teach this topic to other physicians, nursing staff and students. The group first defined teaching objectives and reviewed the scientific literature on the efficacy and use of various vaccines in the elderly. Results were recorded in 217 slides. These slides were grouped to allow their use for short presentations: the immune system in the elderly and general information about vaccination; universal vaccines, influenza vaccines, pneumococcal vaccines, Herpes zoster vaccine, pertussis vaccine, vaccines for old travellers. Written comments were added to most slides to help presenters teach the topics. The content and design of the slides were analyzed and discussed by the whole group. The set was collected in a CD with ready-to-use files for oral presentations. This educational tool was presented and given to French teachers in geriatrics. It has been used for educational sessions in geriatric hospital wards, for continuous medical education for general practitioners and for courses for physicians learning geriatrics. It has also been proposed to physicians in charge of medical coordination of nursing homes and is available on a web site.

Abstract
BACKGROUND Little is known about mortality in nursing home residents with hip fracture. This study examined the effect of pre-fracture characteristics, hospital complications, and post-fracture complications on mortality in residents with hip fracture. METHODS This is a retrospective cohort study of 195 long-term care residents (153 women, 42 men) with hip fracture (1999-2006) followed for mortality until June 30, 2007. Pre-fracture characteristics (age, sex, cognition, functional status, comorbidities, body mass index), hospital complications (acute myocardial infarction, congestive heart failure, delirium, infection) and 6-month complications (delirium, pneumonia, pressure ulcer, urinary tract infection [UTI]) were evaluated as potential predictors of mortality. RESULTS During a median follow-up of 1.4 years, 150 participants (76.9%) died. Male residents were nearly twice as likely to die compared with female residents (hazard ratio [HR] = 1.9, 95% confidence interval [CI] 1.2-3.0). Other pre-fracture characteristics associated with increased mortality included older age (HR per 5 years = 1.3, 95% CI 1.1-1.6), low functional status (HR = 1.7, 95% CI 1.0-3.0), anemia (HR = 1.6, 95% CI 1.1-2.5), and coronary artery disease (HR = 2.0, 95% CI 1.3-2.9). Mortality was 70% greater among residents with a pressure ulcer or pneumonia within 6 months of hip fracture (pressure ulcer, HR = 1.7, 95% CI 1.2-2.6; pneumonia, HR = 1.7, 95% CI 1.1-2.7). Individual hospital complications and post-fracture delirium and UTI were not significant predictors of mortality. CONCLUSIONS In addition to pre-fracture characteristics, potentially modifiable post-fracture complications including pressure ulcer and pneumonia were associated with increased mortality in nursing home residents with hip fracture. Prevention strategies to reduce pressure ulcers and pneumonia may help reduce mortality in this frail population.

Abstract
This study aimed to identify risk factors and assess the impact of coincidental antibiotic therapy on carriage of Streptococcus pneumoniae. Index children from birth to 3 years and their households were recruited from primary health-care registers in four UK general practices. Nasopharyngeal swabs were taken monthly from study participants ten times between October 2001 and July 2002. Multilevel random-effect models were used to adjust for statistical dependence between repeated measurements and family clustering of carriage. Carriage results were available for 3753 swabs from 489 individuals in 121 families. Crude prevalence of carriage was 25%. On multivariable analysis, risk of carriage was reduced by antibiotic use the previous month [odds ratio (OR) 0.34, 95% confidence interval (CI) 0.22-0.52], but increased if a child attended day care for >20 h per week (OR 2.52, 95% CI 1.41-4.52). Taking antibiotics significantly reduces the risk of carriage the following month in a setting with a low prevalence of pneumococcal antimicrobial resistance.

Abstract
Two elderly residents of a care home were hospitalised with pneumonia over a period of one month. They had bacteraemia with penicillin non-susceptible Streptococcus pneumoniae (PNSP) and both died. All residents and staff of the care home were screened for PNSP using nasopharyngeal swabs, with one resident and one member of staff found to be asymptomatic carriers. Oral rifampicin was given to the carriers. All four strains were found to be serotype 14, and multilocus sequence typing (MLST) showed ST2652, not previously detected in Scotland. Review of care home residents showed that pneumococcal vaccination coverage was low (63%). This is similar to rates found in those aged > or =65 years in the general population and needs to be improved upon.

Abstract
BACKGROUND Studies on adherence to infection control policies in nursing homes (NHs) are limited. This pilot study explores the use of various infection control practices and the role of infection control practitioners in southeast Michigan NHs. METHODS A 43-item self-administered questionnaire and explanatory cover letter were mailed to 105 licensed NHs in southeast Michigan. A second mailing was sent to the nonresponders 4 weeks later. RESULTS Significant variability existed in adoption of various infection control measures with respect to time spent in infection control activities (50% of facilities having a full-time infection control practitioner), definitions used in monitoring infections, and immunization rates (influenza: range, 0%-100%; mean, 73.2%; pneumococcal: range, 0%-100%; mean, 38.5%). CONCLUSION Although strides have been made in infection control research in NHs, significant variations exist in implementation of infection control methods and guidelines. Future research should focus on identifying barriers to infection control in NHs.

Abstract
The infectious risk in long-term care facilities and nursing homes is significant. Patients living in those facilities are very old, with a poor health status, and a high degree of dependency. The risk for epidemic outbreaks, in particular with viruses, is very high. A simple system for surveillance and action, in relation with hospital infection control units, is mandatory. An educational program is needed to define the prevention program based on the use of hand disinfection and other standard precautions, anti-viral and pneumococcal vaccination. The program must be simple, pragmatic, allowing to maintain social links and quality of life, which are essential for these patients. A strong cooperation between these long-term care facilities and nursing homes, general practitioners, healthcare team, and relatives is necessary.
