An analysis of reported cases shoulder injury related to vaccine administration of after COVID-19 vaccination. Hum Vaccin Immunother 2024; 20:2321672. [PMID: 38439670 PMCID: PMC10936633 DOI: 10.1080/21645515.2024.2321672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 02/18/2024] [Indexed: 03/06/2024] Open
Abstract
To prevent COVID-19, the COVID-19 vaccine has been widely administered worldwide, but various complications accompany this vaccine. The aim of this study was to investigate the demographic patterns, clinical features, diagnostic findings, and treatment outcomes associated with shoulder injury related to vaccine administration (SIRVA). This study examined 22 patients with SIRVA following COVID-19 vaccination from the Web of Science (WOS) and PubMed databases. The patients were categorized based on sex, age, type of COVID-19 vaccine received, dose administered, latency of symptom onset, and the presence of specific clinical manifestations. Patients, evenly distributed by sex (12 females, 10 males), and aged 21 to 84 years (mean age 46.6), were analyzed. SIRVA cases were reported across all age groups. The Pfizer - BioNTech COVID-19 vaccine had the highest incidence (n = 8), followed by the Oxford/AstraZeneca COVID-19 vaccine (n = 4). Symptoms, primarily shoulder pain (n = 22) and shoulder mobility disorders (n = 18), occurred within three days post-vaccination. Some patients also reported shoulder swelling (n = 5) and fever (n = 2). Imaging revealed nonspecific X-ray findings, supraspinatus tendon calcification (n = 2), and shoulder edema and inflammation on MRI (n = 12). This study provides insights into the clinical aspects of SIRVA related to COVID-19 vaccination. Recognition and appropriate management of these complications are crucial for optimal patient outcomes.

Development of mRNA nano-vaccines for COVID-19 prevention and its biochemical interactions with various disease conditions and age groups. J Drug Target 2024; 32:21-32. [PMID: 38010097 DOI: 10.1080/1061186x.2023.2288996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Accepted: 11/18/2023] [Indexed: 11/29/2023]
Abstract
This review has focused on the development of mRNA nano-vaccine and the biochemical interactions of anti-COVID-19 mRNA vaccines with various disease conditions and age groups. It studied five major groups of individuals with different disease conditions and ages, including allergic background, infarction background, adolescent, and adult (youngsters), pregnant women, and elderly. All five groups had been reported to have background-related adverse effects. Allergic background individuals were observed to have higher chances of experiencing allergic reactions and even anaphylaxis. Individuals with an infarction background had a higher risk of vaccine-induced diseases, e.g. pneumonitis and interstitial lung diseases. Pregnant women were seen to suffer from obstetric and gynecological adverse effects after receiving vaccinations. However, interestingly, the elderly individuals (> 65 years old) had experienced milder and less frequent adverse effects compared to the adolescent (<19 and >9 years old) and young adulthood (19-39 years old), or middle adulthood (40-59 years old) age groups, while middle to late adolescent (14-17 years old) was the riskiest age group to vaccine-induced cardiovascular manifestations.

Immune Response to an Inactivated Vaccine of SARS-CoV-2 (CoronaVac) in an Indigenous Brazilian Population: A Cohort Study. Vaccines (Basel) 2024; 12:402. [PMID: 38675784 PMCID: PMC11053429 DOI: 10.3390/vaccines12040402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 02/07/2024] [Accepted: 03/30/2024] [Indexed: 04/28/2024] Open
Abstract
INTRODUCTION Although the adaptive immune responses to the CoronaVac vaccine are known, their dynamics in indigenous communities remain unclear. In this study, we assessed the humoral and cellular immune responses to CoronaVac (Sinovac Biotech Life Sciences, 2021 NCT05225285, Beijing, China), in immunized Brazilian indigenous individuals. METHODS We conducted a prospective cohort study on indigenous Brazilian people between February 2021 and June 2021. Analyses of immune responses were carried out before (T1) and after a vaccination schedule was completed (T2). Demographic data were collected using a questionnaire. RESULTS We initially included 328 patients; among them, 120 (36.6%) had no SARS-CoV-2 antibodies. Peripheral blood mononuclear cells (PBMCs) were collected from 106 patients during follow-up visits, of which 91 samples were analyzed by immunophenotyping assay to detect SARS-CoV-2-specific memory T-cell response. Post-vaccination, the levels of memory B-cells and Natural Killer T-lymphocytes increased. Bororó village residents, females, and Terena ethnic group members had higher levels of anti-spike IgG antibodies post-vaccination, whereas alcohol and tobacco users had lower concentrations. CONCLUSIONS To our best knowledge, this was the first comprehensive assessment of antibody and T-cell responses against CoronaVac vaccination in indigenous patients. Our findings showed that antibody response and T-cell immunity against SARS-CoV-2 were present in most patients following the vaccination schedule.

Right Biceps Pseudo-Tumor from COVID-19 Vaccination. Vaccines (Basel) 2024; 12:160. [PMID: 38400143 PMCID: PMC10892541 DOI: 10.3390/vaccines12020160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 01/31/2024] [Accepted: 02/01/2024] [Indexed: 02/25/2024] Open
Abstract
Delayed hypersensitivity reactions (DHRs) have been reported in association with COVID-19 vaccines, particularly those that are mRNA-based. Classic DHRs result in induration, erythema, tenderness, and urticaria. However, soft tissue mass is an uncommon complication of a COVID-19 vaccination-associated DHR and is rarely reported in the literature. We present a case of a 49-year-old male who recognized a mildly painful, firm soft tissue mass within the biceps mimicking neoplasm six months after receiving the booster dose of the Moderna vaccine. Non-operative conservative treatment modalities, including heating pads, ice packs, acetaminophen, and ibuprofen, failed to improve the patient's mass. The mass, which proved histologically to be an inflammatory pseudo-tumor, did not recur after complete excision. While there have been many reported cases of DHRs following COVID-19 vaccinations, we present this case to raise awareness of the development of pseudo-tumors as a possible, yet rare, clinical manifestation of DHRs following vaccination.

Abstract
Mucormycosis is a rare, life-threatening fungal infection. While typically affecting immunosuppressed individuals, cases in the immunocompetent have been reported, particularly secondary to trauma, and the subspecies Apophysomyces. These fungi are typically difficult to isolate. This case report describes cutaneous Mucormycosis caused by Apophysomyces complex at a vaccination site, given following a motor vehicle accident. This life-threatening infection occurred in an immunocompetent 17-year old girl, resulting in multiple hospital admissions and finally, radical surgical debridement of her left upper limb. This case highlights the aggressive nature of this infection and the importance of early clinical recognition as effective treatment requires aggressive debridement typically prior to microbiological confirmation.

The prevalence and clinical course of shoulder injury related to vaccine administration (SIRVA) after COVID-19 vaccines in Dutch hospital workers. Vaccine 2023; 41:6042-6047. [PMID: 37635003 DOI: 10.1016/j.vaccine.2023.08.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 08/09/2023] [Accepted: 08/15/2023] [Indexed: 08/29/2023]
Abstract
INTRODUCTION Shoulder Injury Related to Vaccine Administration (SIRVA) is a rare disorder characterized by persistent shoulder pain and limited range of motion presenting within 48 h after vaccine administration. With the widespread distribution of the COVID-19 vaccine, the incidence of SIRVA is expected to rise. This sudden rise in vaccine administration presents an ideal opportunity to estimate the prevalence of SIRVA and to better characterize SIRVA. OBJECTIVE This study aims to investigate the prevalence of SIRVA following COVID-19 vaccine administration among hospital workers in the Netherlands. METHODS A questionnaire was sent to all hospital workers from a single non-academic hospital in the Netherlands. Respondents who had active SIRVA complaints were invited for an outpatient orthopaedic clinic assessment. Data was collected on participant characteristics and physical examination including assessment of active and passive range of motion (ROM). An ultrasound was performed to identify potential abnormalities. RESULTS 32 out of 981 (3.3%) respondents reported shoulder pain with limited ROM occurring within 48 h after vaccine administration lasting for at least 7 days. Of these 32 respondents with SIRVA, 18 (56.2%) still reported active symptoms at the time of the survey. Clinical examination of 13 (72.2%) respondents with active SIRVA complaints showed limited glenohumeral ROM, limitations in activities of daily living and injection site pain. Twelve out of thirteen (92.3%) respondents with active SIRVA complaints showed abnormalities of the soft-tissue of the shoulder on ultrasound. Physiotherapy was the most common treatment modality for persistent SIRVA complaints (38.9%). CONCLUSIONS The prevalence of SIRVA is estimated at 3% in the adult working population. Signs and symptoms of SIRVA are variable in severity, localization and timing. Soft-tissue abnormalities is the most common clinical sign. This study contributes to clinician's knowledge on SIRVA, aiding in early recognition and treatment, which are imperative for prevention of persistent and severe shoulder pathology.

Abstract
Introduction Shoulder injury related to vaccine administration (SIRVA) is a group of pathologies defined by pain and stiffness after intramuscular administration of vaccine to the upper arm and has been reported after COVID-19 vaccination. We aim to discuss its pathophysiology, clinical presentation, treatment and outcomes. Materials and methods We retrospectively identified patients presenting with adhesive capsulitis within four weeks of administration of COVID-19 vaccine to the affected arm at our tertiary institution from March 2021 to December 2022. Result Based on the above criteria, we identified seven cases of adhesive capsulitis, comprising one male and six female patients, with average age of 60 years. We present initial symptoms, signs and the duration from when the vaccine was administered. We have highlighted our treatment strategies as well as the clinical and functional outcomes reported by these patients after treatment. We have reported improvement in both Visual Analogue Scale (VAS) and range of motion (ROM) in all our patients after non-surgical management which included physiotherapy and, in some cases, hydrodilatation. Conclusion SIRVA related adhesive capsulitis is rare and under-reported with limited information in current literature. This study highlights that adhesive capsulitis is a potential complication arising from improper COVID-19 vaccine administration and reinforces traditional wisdom of administering vaccinations on the non-dominant arm. Conservative treatment strategies appear to be effective, particularly hydrodilatation combined with physiotherapy, and patients are expected to have a good return of function.

Shoulder Injury Related to Vaccine Administration (SIRVA) Is Real: A Case Report. Vaccines (Basel) 2023; 11:1164. [PMID: 37514980 PMCID: PMC10386640 DOI: 10.3390/vaccines11071164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 06/19/2023] [Accepted: 06/24/2023] [Indexed: 07/30/2023] Open
Abstract
This study presents a case of SIRVA-induced adhesive capsulitis and the subsequent physiotherapy intervention. It details the patient's journey using CARE guidelines. The main symptoms included persistent pain and a reduced range of motion for flexion, abduction, and internal and external rotation of the shoulder. Interventions included active and passive mobilisation via capsular stretching, and home exercise programs. At more than two years post-injury, the patient has ongoing pain, restricted shoulder movement, and disability. This highlights the importance of healthcare practitioners' knowledge of SIRVA. Vaccinating practitioners should be aware of the mechanism of injury of SIRVA for preventing such injuries. First-contact practitioners should be aware of SIRVA-induced conditions to ensure timely and correct diagnosis and management of SIRVA-induced conditions.

Abstract
BACKGROUND Current recommendations for needle length and vaccination site for intramuscular deltoid vaccinations are backed by minimal data. AIM To determine the ideal needle length and vaccination site for intramuscular deltoid vaccine administration. METHODS 120 shoulder CT scans were evaluated and grouped by patient weight and sex as recommended by the United States CDC: Group 1, <60 kg, Group 2, 60-70 kg, Group 3, females 70-90 kg and males 70-118 kg, and Group 4, females > 90 kg and males > 118 kg. For each group, distance from skin to deltoid fascia and deltoid muscle width were measured at 2, 4, and 6 cm distal to the posterolateral corner of the acromion for 5 unique trajectories. Needle lengths of 0.625″, 1.0″, and 1.5″ were simulated at each site to determine inoculation location relative to the deltoid. RESULTS For Group 1, a 0.625″ needle in the mid-lateral (ML) trajectory 4 cm distal to the posterolateral corner provided a perfect rate of successful inoculations (100 %). For Groups 2-3, a 1″ needle in the posterolateral (PL) trajectory 4 cm distal provided high rates (>80 %) of successful intramuscular inoculations with low rates of overpenetration (<15 %) while minimizing risk to the axillary nerve. For Group 4, a 1.5″ needle using the same strategy provided the highest rate of successful inoculations (96 %) and minimal overpenetration (4 %). Overpenetration was associated with more anterior and superior injection sites (P < 0.001 for both) for all needle lengths. CONCLUSIONS The overall ideal injection site to maximize successful intramuscular vaccine administration, minimize overpenetration, and avoid axillary nerve injury is 4 cm distal to and in line with the posterolateral corner of the acromion, a site more posterior and inferior than current CDC recommendations. We caution against use of a 1.5″ needle for patients < 118 kg due to high predicted rates of overpenetration.

Abstract
ABSTRACT Of the many bizarre complications of administration of the COVID 19 vaccine, adhesive capsulitis is almost unheard of, although shoulder injury related to vaccine administration, which by definition has symptom onset within 48 hrs and is caused by faulty injection technique, has been rarely reported. Nine cases of adhesive capsulitis, five males and four females with a mean age of 48.7 ± 12.7 yrs, presenting within 1 mo of intramuscular Covishield vaccine on the ipsilateral deltoid and fulfilling the standard UK FROST Multicenter Study diagnostic criteria are reported. The mean time interval from vaccination until symptom onset was 12.3 ± 3.1 days, and mean symptom duration was 9.4 ± 2.4 wks. Conventional treatment with nonsteroidal anti-inflammatory drugs, followed by intra-articular steroid injection coupled with suprascapular nerve steroid block, improved the pain score and range of movement in 8 wks. The exact pathogenesis remains an enigma, although mechanisms such as local spread via deltoid muscle microvasculature, nerves, or shoulder injury related to vaccine administration causing secondary adhesive capsulitis have been hypothesized. While adhesive capsulitis is a very common diagnosis in the physiatric outpatient setting, the possible association with Covishield vaccination, the Indian version of the Oxford AstraZeneca recombinant ChAdOx1 nCoV-19 vaccine, is almost absent in existing literature and hence likely to be missed by clinicians, which necessitates this report.

Abstract
Hypersensitivity reactions to the COVID-19 mRNA vaccines were identified in the initial 2020 trials. Appearance of a soft tissue mass is a rare manifestation of this hypersensitivity reaction. In this patient, bilateral injections resulted in the appearance of shoulder masses. Magnetic resonance imaging showed localized pseudo-tumorous edema in both shoulders, one subcutaneous and the other intramuscular. This is only the second case of a mass-like reaction to the COVID-19 vaccine mimicking a possible soft tissue neoplasm. Improper vaccination administration technique may have contributed to this complication. The case is presented to increase awareness of this potential pseudotumor.

Abstract
Background/purpose Although many coronavirus disease 2019 (COVID-19) vaccine injections have been administered worldwide, the safety of this practice remains unclear. This study aimed to compare the rates of complications associated with COVID-19 vaccines administered by dentists with those of vaccines administered by nurses. This study aimed to evaluate the safety of a vaccination program delivered by dentists. Materials and methods This observational cohort study included 537 recipients of the second dose of the Pfizer COVID-19 vaccine, delivered as an intramuscular injection to the upper arm deltoid muscle by dentists or nurses at the study site. Vaccine recipients were divided into two groups according to the vaccination administrator (dentist vs. nurse groups). The rates of complications associated with intramuscular injection technique (numbness in the hand or arm at the time of the injection, vasovagal reflex at the time of the injection, vaccine-related shoulder injury, and prolonged numbness) were examined. Results A total of 125 vaccine recipients were included (nurse group, n = 84; dentist group, n = 41). The overall incidence rate of complications was lower in the dentist group (2.4%; 1/41) than in the nurse group (8.3%; 7/84). However, this difference was not statistically significant (P = 0.3). Conclusion This study suggests that the safety of COVID-19 vaccine administration is comparable between dentists and nurses.

Abstract
INTRODUCTION Intramuscular administration of vaccines into the deltoid muscle is the recommended route for most vaccines in adults. Ectopic injection into the subdeltoid/subacromial bursa can produce an inflammatory bursitis that is associated with significant long-term morbidity. CASE REPORT We describe a novel approach to treatment of this condition: ultrasound-guided administration of dexamethasone by the emergency physician within six hours of vaccine administration. This approach resulted in complete and durable long-term resolution of symptoms with no functional impairment. CONCLUSION This outcome is superior to that described for usual care, and the approach is well-suited to emergency physicians.

Abstract
BACKGROUND Persistent shoulder pain and dysfunction after vaccination are relatively rare but well-known complications after inoculations into the deltoid muscle. The term SIRVA (shoulder injury related to vaccine administration) is frequently used to encompass many of these occurrences; however, multiple distinct pathologies with similar presentations have been reported after vaccination. We performed a systematic review of the literature on vaccine-related shoulder injuries to help guide practitioners in appropriate workup and treatment based on specific diagnoses. METHODS PubMed was used to search for combinations of multiple keywords (including vaccine, immunization, SIRVA, injury, inflammation, bursitis, Parsonage-Turner syndrome, and neuritis), and all references of each potential article were reviewed. A total of 56 articles were included. Patient demographics, vaccine information, presentation, diagnostic studies, treatment, and outcomes were recorded. RESULTS Diagnoses were divided into 3 categories: (1) local inflammatory reaction (SIRVA), (2) brachial neuritis, and (3) direct nerve injury. The included articles reported on 57 cases of SIRVA, 18 of brachial neuritis, and 4 of direct nerve injury. The diagnoses reported for the SIRVA cases included frozen shoulder, pseudoseptic arthritis, subacromial bursitis, rotator cuff injury, and lytic lesions of the humeral head. Various treatments were used, and most patients had resolution of symptoms with conservative treatment including physical therapy, analgesics, and/or corticosteroid injections. Advanced imaging rarely provided information that affected treatment. The brachial neuritis and direct nerve injury cases were typically confirmed with electromyography/nerve conduction studies. Treatment of these 2 categories was nonoperative in all cases, typically with analgesics and/or corticosteroids, and most patients had symptomatic improvement after a few months, with most patients regaining strength. However, some (1 of 3 patients with brachial neuritis and >1 year of follow-up and 2 of 4 patients with direct injury) had residual weakness. CONCLUSIONS Medical professionals should be aware of the various pathologies that can lead to prolonged shoulder pain after vaccination. Fortunately, most of these conditions can be treated successfully with nonoperative modalities, although differentiating among the diagnoses can help guide treatment, as some likely benefit from systemic corticosteroids or localized corticosteroid injections. Outcomes for most patients have been good, with the majority recovering without residual pain or deficits. LEVEL OF EVIDENCE Prognostic Level IV.

Abstract
CoronaVac, also known as the Sinovac inactivated SARS-CoV-2 vaccine, has been widely implemented in combating the COVID-19 pandemic. We summarized the results of clinical trials and real-world studies of CoronaVac in this review. The overall efficacy for the prevention of symptomatic COVID-19 (before the emergence of variants of concern) using two doses of 3 μg CoronaVac was 67.7% (95% CI, 35.9% to 83.7%). Effectiveness in preventing hospitalizations, ICU admissions, and deaths was more prominent than that in preventing COVID-19. A third dose inherited the effectiveness against non-variants of concern and increased effectiveness against severe COVID-19 outcomes caused by omicron variants compared to two doses. Most adverse reactions were mild. Few vaccine-related serious adverse reactions have been reported. Moreover, three-dose regimen significantly increased the seroconversion levels of neutralizing antibodies against omicron as compared to two-dose regimen. This review of CoronaVac may provide a scientific basis for optimizing global immunization strategies.

Abstract
Background and Introduction Intramuscular injections are usually given in the arm or the gluteal region. Needle insertions done through the intramuscular route in the arm are almost always administered at a point 1 - 2 cm above the insertion of the deltoid. However, this site is not such an ideal one as found by certain other workers. Hence, this study was done to establish a series of safe determinant points in and around the arm in the South Indian population of the state of Telangana. Materials and Methods The five proven safe injection points were tested through needle insertions by observing sterile aseptic precautions in the arms of 370 subjects at the outpatient department of a national level medical research institute after obtaining their consent following the universal safety protocol. Results The points I [1 to 2 cm above deltoid insertion], II [a point midway between the midpoint of arm and insertion of deltoid] and III [midpoint between anterior acromion and deltoid insertion] were found to be safe for administering intramuscular arm injections in this subset of the population. Conclusion This explains the erratic course of the anterior branches of the axillary nerve in different geographical populations. Hence, needle insertion points for arm intramuscular injections need to be determined according to the region.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2022; 41:1295-1297. [PMID: 34403167 PMCID: PMC8426865 DOI: 10.1002/jum.15813] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 08/01/2021] [Accepted: 08/02/2021] [Indexed: 06/13/2023]
Abstract
Coronavirus disease 2019 has become a widespread public health crisis across the globe, requiring multiple approaches to containment, treatment, and prevention. Vaccines are an important tool to prevent morbidity and mortality from this devastating virus. Ensuring direct administration of vaccines into target tissue helps provide an optimal immune response while decreasing unintended adverse effects. Point-of-care ultrasound can better assist clinicians to determine appropriate needle length and penetration level especially in special populations. Examples include patients who are obese, pregnant, or with refractory lymphedema, and those living in areas where needle supply is unstable or insufficient.

SIRVA (Shoulder Injury Related to Vaccine Administration) following mRNA COVID-19 Vaccination: Case discussion and literature review. Vaccine 2022; 40:2546-2550. [PMID: 35339304 PMCID: PMC8934720 DOI: 10.1016/j.vaccine.2022.03.037] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 03/06/2022] [Accepted: 03/16/2022] [Indexed: 01/17/2023]
Abstract
Shoulder injury related to vaccine administration (SIRVA) is an increasingly recognised complication after vaccination and presents with significant shoulder pain and stiffness. SIRVA is thought to occur as a result of improper administration of vaccine into the subdeltoid bursa or shoulder joint. This results in an inflammatory cascade that damages the structures in the shoulder region. The incidence of SIRVA is relatively higher for influenza vaccination due its widespread administration. We present a reported case of SIRVA following a mRNA COVID-19 vaccination and review the current literature. As we embark on a worldwide scale of COVID-19 vaccination, it is of utmost important that we use proper vaccination techniques and screen patients at risk of SIRVA. This would improve the efficacy of the vaccine and improve the outcomes of the vaccination programme.

Deltoid Intramuscular Injections: A Systematic Review of Underlying Neurovascular Structures to the Muscle and Proposing a Relatively Safer Site. Cureus 2022; 14:e24172. [PMID: 35592188 PMCID: PMC9110073 DOI: 10.7759/cureus.24172] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/15/2022] [Indexed: 12/02/2022] Open
Abstract
The deltoid is the preferred site for intramuscular injection (IMI) because of its easy accessibility for drug and vaccine administration. Government immunization advisories, standard anatomy textbooks, and researchers have proposed various injection techniques and sites, but specific guidelines are lacking for the administration of IMIs in the increasingly used deltoid site. This study analyzes the procedures of administering IMIs in the deltoid related to the neurovascular network underlying the muscle and proposes a preferred site with the least chance of injury. The review protocol was submitted with PROSPERO (ID: 319251). PubMed, Google Scholar, and Websites of National Public Health Agencies were searched from 1950 up to 2022 for articles, advisories, and National Immunization Guidelines using Medical Subject Headings (MeSH) terms, including IMIs, deltoid muscle, safe injection sites, to identify recommendations for safer sites and techniques of administering deltoid IMIs. All the authors strictly adhered to a well-developed registered review protocol throughout the study and followed the risk of bias in systematic reviews (ROBIS) guidance tool. The proposed sites and landmark data were tabulated, and each site was analyzed based on the underlying neurovascular structures. Data were depicted by self-generated images. The initial search identified 174 articles. After applying the inclusion and exclusion criteria, 57 articles were shortlisted. Out of the 39 selected articles, 18 focused on the administration of deltoid IMIs, whereas seven focused on the variations in the underlying neurovascular structures in proximity to the deltoid muscle. The remaining 14 articles were the immunization guides issued by the National Public Health Agencies of the Government of India and abroad, whose data was used for comparison. Twelve deltoid IMI sites and techniques were identified. A site 1-3 fingerbreadths/5 cm below the mid-acromion point (7 studies); mid-deltoid site/densest part of the deltoid (1 study); a site at the middle third of the deltoid muscle (1 study); triangular injection site (1 study). Limitations included the unavailability of free access to complete text in many articles resulting in exclusion. The area around the shoulder joint and up to the lower level of the intertubercular sulcus is highly vascularized by the presence of many anomalous arterial patterns. To avoid injury, a safer site is proposed of 5 fingerbreadths/10 cm below the midpoint of the lateral border of the acromion. The authors received no specific funding for this study except for the journal publication charges.

Abstract
Shoulder pain is often a transient physical finding after vaccination. We present the case of a 46-year-old woman who presented clinically with frozen shoulder that was progressively worse and temporally related to her yearly influenza vaccination. The patient failed conservative management, and 7 months postvaccination, the patient underwent shoulder manipulation under anesthesia with good results. Vaccination-related shoulder dysfunction after high-deltoid intramuscular penetration and infiltration into the subdeltoid/subacromial bursa can cause a severe local inflammatory response that clinically may present as frozen shoulder. A case report and review of the literature on suspected frozen shoulder injury related to vaccine administration is presented. A greater understanding of the shoulder anatomy and use of the correct intramuscular vaccination administration technique is important to prevent this rare postvaccination complication.

Abstract
Shoulder injury related to vaccine administration (SIRVA) is a rare but potentially debilitating injury characterized by persistent shoulder pain, typically occurring within 48 hours of intramuscular deltoid vaccine administration. With over 150 million flu vaccines being administered in the United States each year, and the US Centers for Disease Control’s goal of immunizing greater than 70% of the population for the coronavirus disease 2019 virus, cases of SIRVA can be expected to rise. A search of current literature was done to identify published material corresponding to incidence, diagnosis, and treatment of SIRVA. Most events have been associated with poor needle placement and/or a local reaction to the delivered serum during vaccine administration. Shoulder injury related to vaccine administration events can lead to persistent and possibly permanent injury. Clinical evaluation involves a thorough history, physical examination, and often diagnostic studies including radiographs, magnetic resonance imaging, and nerve studies. Treatment is individually directed and should initially consist of observation and local symptom management. Recalcitrant cases or infections may warrant surgical intervention. Published outcomes vary widely, and our understanding of SIRVA remains limited. Large-scale studies are necessary to better understand the pathophysiology of SIRVA, its treatment, and its outcomes. Overall, the initial priority in managing SIRVA should be awareness and prevention.

Abstract
In recent years, personalized cancer vaccines have gained increasing attention as emerging immunotherapies with the capability to overcome interindividual differences and show great benefits for individual patients in the clinic due to the highly tailored vaccine formulations. A large number of materials have been studied as delivery vectors to enhance the therapeutic performance of personalized cancer vaccines, including artificial materials, engineered microorganisms, cells and cell derivatives. These delivery vectors with distinct features are employed to change antigen biodistributions and to facilitate antigen uptake, processing and presentation, improving the strength, velocity, and duration of the immune response when delivered by different strategies. Here, we provide an overview of personalized cancer vaccine delivery vectors, describing their materials, physicochemical properties, delivery strategies and challenges for clinical transformation.

Inadequate deltoid muscle penetration and concerns of improper COVID mRNA vaccine administration can be avoided by injection technique modification. Vaccine 2021; 39:5326-5330. [PMID: 34275671 PMCID: PMC8249688 DOI: 10.1016/j.vaccine.2021.06.081] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2021] [Revised: 06/23/2021] [Accepted: 06/25/2021] [Indexed: 11/02/2022]
Abstract
BACKGROUND Recent phase-3 clinical trials have demonstrated very encouraging results for mRNA based vaccines against COVID-19. Current FDA and manufacturer guidelines mandate intramuscular administration of these vaccines, as other administration routes may not provide the same levels of effectiveness and safety. Observing the vast amount of published media images of persons receiving their vaccines, the authors noted in many cases the injection technique involved skin bunching, raising concerns of inadequate deltoid muscle penetration and consequent lowered vaccine efficacy. Our study hypothesis was that skin bunching will increase the skin-to-muscle distance over 20 mm, the maximal distance allowing the required 5 mm muscle penetration with a 25 mm needle. MATERIALS AND METHODS 60 adult volunteers from our hospital staff were recruited, and using ultrasound, the skin-to-muscle distance measured in three positions: flat, skin bunching and muscle bunching. The skin-to-muscle distance difference and correlation with gender and BMI were calculated. RESULTS Skin bunching significantly increased the skin-to-muscle distance in all subjects. In 6 (10%) subjects, this increase exceeded the 20 mm limit. Having a skin-to-deltoid distance of 20 mm or more strongly correlated with a BMI of 30 or more. CONCLUSIONS Skin bunching will prevent adequate intramuscular injection of vaccines in a small percentage of persons, but as hundreds of millions are expected to receive mRNA vaccines in the coming months, the multiplied result can have significant personal and societal consequences for millions of people globally, especially in obese populations, and therefore this practice should be strictly discouraged.

Shoulder injury related to Sinovac COVID-19 vaccine: A case report. Ann Med Surg (Lond) 2021; 68:102622.

Abstract
Introduction After a vaccination, patients frequently have clinical symptoms of pain and swelling over the injection area which usually resolve 2–3 days after the injection. If the symptoms do not improve, a shoulder injury related to vaccine administration (SIRVA) will be considered, perhaps related to an improper injection technique. Herein we report our first case of a SIRVA after a Sinovac COVID-19 vaccination which occurred due to deep penetration and direction of the needle. The clinical symptoms of the patient improved after treatment with combined oral non-steroidal anti-inflammatory drugs and a short course of intravenous antibiotic. Case presentation A 52-year-old Thai male without prior shoulder pain had a Sinovac COVID-19 vaccination at his right shoulder. The injection was given by a nurse using a 27-gauge needle, 1.5 inches in length. The injection landmark was 3 finger breadths below the midlateral edge of the acromial process. The direction of the needle was 45° to the skin cephalad. Three days after receiving the vaccine the patient began to have right shoulder pain with limited range of motion and acute fever. He was admitted for medical treatment which his clinical symptoms gradually improved. Conclusion We report a case of subacromial-subcoracoid-subdeltoid bursitis following a Sinovac COVID-19 vaccine injection. This condition is rare, and usually related to an incorrect vaccination technique. To avoid this complication, nurses should identify the correct landmark, use an appropriate needle length, and point the needle in the correct direction. After a vaccination, if the symptoms do not improve, SIRVA will be considered. There is a risk of SIRVA if the direction of the needle was pointed to the skin cephalad. Before diagnosis SIRVA, septic arthritis of shoulder should be ruled out.

Abstract
An estimated 350 million people are living with chronic Hepatitis B virus (HBV) worldwide. Preventative HBV vaccination in infants has reduced the disease burden; however, insufficient immunization programs and access obstacles leave vulnerable populations at risk for infection in endemic regions. Gene electrotransfer (GET) using a noninvasive multielectrode array (MEA) provides an alternative platform for DNA vaccination in the skin. DNA vaccines are nonlive and nonreplicating and temperature stable unlike their counterparts. In addition, their simple engineering allows them to be manufactured quickly at a low cost. In the current work, we present the combination of GET and moderate heating for delivery of a DNA vaccine against HBV. Our laboratory has previously shown the synergy between moderate tissue preheating at 43°C and GET with the MEA as a means to reduce both the applied voltage and pulse number to achieve similar if not higher gene expression than GET alone. In this study, we expand upon this work, by optimizing the plasmid dose to achieve the highest level of expression. Using the reporter gene luciferase, we found that an intradermal injection of 100 μL at 1 mg/mL induced the highest expression levels across all tested GET conditions. We then evaluated our moderate heat-assisted GET platform for the intradermal delivery of a plasmid encoding Hepatitis B surface antigen (pHBsAg) via a prime and prime plus boost vaccination protocol. At 18 weeks, following the prime plus boost protocol, we observed that a high-voltage low-pulse GET condition with moderate heating (45 V 36 p+heat) generated antibodies against Hepatitis B surface antigen (HBsAb) at peak measuring 230-fold over injection of plasmid DNA alone with moderate heating. HBsAbs remained robust over the 30-week observation period. These data suggest that moderate heat-assisted GET has the potential to induce strong immune responses, an attractive feature for development of an alternative vaccine delivery platform.

Abstract
Shoulder injury related to vaccine administration (SIRVA) is defined as "shoulder pain with limited range of motion within 48 hours after vaccine receipt in individuals with no prior history of pain, inflammation, or dysfunction of the affected shoulder before vaccine administration." Corticosteroid injections (CSIs) have been proposed as a reasonable treatment modality for SIRVA, although evidence regarding efficacy is scanty. In this case series, we present two patients diagnosed with SIRVA who received CSI within 5 days of symptom onset and saw symptom resolution within 1 month. This is in comparison to a Centers for Disease Control and Prevention report that showed 65% of patients with SIRVA will have pain lasting longer than 1 month, and 25% will have pain lasting longer than 3 months. Our case series shows that CSIs may be an effective treatment modality for SIRVA. It would be reasonable to use CSIs as a first line treatment and should especially be considered in patients who have contraindications to nonsteroidal anti-inflammatory drugs.

Adverse events following immunization: Findings from 2017/2018 measles vaccination campaign, Nigeria AEFI reporting in 2017/2018 measles vaccination campaign. Vaccine 2021; 39 Suppl 3:C82-C88. [PMID: 33714655 DOI: 10.1016/j.vaccine.2021.02.067] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 02/19/2021] [Accepted: 02/26/2021] [Indexed: 11/21/2022]
Abstract
INTRODUCTION An Adverse event following immunization (AEFI) is an untoward medical occurrence following immunization and which may not have a necessary causal relationship with the usage of a vaccine. The World Health Organization categories AEFI into two; serious and non-serious. An AEFI is considered serious if it is life-threatening, requires inpatient hospitalization or results in death. The measles vaccine is safe and effective however because it is a live-attenuated injectable vaccine it is more prone to AEFI as compared to non-injectable vaccines when given in large numbers over a short period as is the nature of measles mass vaccination campaigns (MVC). This article describes Nigeria's experience on AEFI reporting during the 2017/2018 Measles vaccination campaign (MVC). METHODS We reviewed various materials which included the Open Data Kit (ODK) which is an open source smartphone-based data collecting tool, operations room reports, measles campaign tally sheets, AEFI line listing forms, the post measles campaign coverage survey report and the report of the AEFI national expert committee review of the 2017/2018 Nigeria measles MVC. RESULTS A total of 6,214 suspected cases of AEFI were line listed from all 36 states and the Federal Capital Territory(FCT) during the 2017/2018 MVC with Fever(38%) and pain at injection site the (30%)most common reports. Overall, 99.7% AEFIs were reported to be non-serious AEFIs, with almost all cases resolved fully with no long-term sequalae.. The national incidence of suspected AEFI per 100,000 population was 16.3 with subnational incidence highest in Kebbi state (101.3/100,000) and lowest in Bayelsa state (0.8/100,000). CONCLUSION Adequate AEFI reporting, Investigation and management remains important in managing the risk of a disruption of mass campaigns. The deployment of supervisors during campaign may play an important role in improving the identification and reporting of suspected AEFI. Further inquiries about AEFIs during the post campaign coverage evaluation also played a role in improving AEFI reporting and documentation. The real-time, on the spot, follow up by the national operations team helped with decision making and intervention including AEFI investigations and assessments.

Abstract
BACKGROUND Vaccinations have been widely used worldwide since their invention to prevent various diseases, but they can also have some adverse effects ranging from mild local reactions to serious side effects. These adverse effects are generally self-limited and resolve within a short time without any treatment. While a sterile abscess following vaccination is a rare condition in adults, many cases have been reported regarding children in the literature. Here, we report a case of recurrent sterile abscesses, which occurred after a Td vaccination, treated with corticosteroids. CASE PRESENTATION A 22-year old woman was admitted to our department with a complaint of swelling at the site of the vaccination. On physical examination, this mass was about 6 × 6 cm in size and fluctuating, but there were no pain complaints and no redness present. She had received her Td vaccination 3 weeks ago and the swelling had started at the site of the injection 4 days following this immunization. Oral amoxicillin/clavulanic acid and local antibiotic cream were administered for 10 days. The laboratory values were unremarkable. Despite the administration of antibiotics, the swelling did not regress, and on the contrary, continued to increase in size. On ultrasound, two interconnected abscesses were observed in the subcutaneous area, and did not involve the muscle tissue. Later, the abscesses were completely drained, and the samples were cultured. The current antibiotics were continued. The gram staining of the samples revealed abundant leukocytes but no microorganisms. The solid and liquid cultures of the materials remained negative. Despite the administration of multiple drainages and antibiotics, the mass recurred. Finally, the patient was considered to have a sterile abscess due to Td immunization. The antimicrobials were stopped. Local and oral corticosteroids were initiated. The swelling regressed significantly, and the treatments continued for 7 days. The patient has been doing well and has had no recurrence for over a year. CONCLUSIONS Corticosteroids appeared to improve the patient and therefore we suggest that the efficacy and route of administration of steroids in this situation should be explored further.

Abstract
A 61-year-old female presented three months following an influenza vaccination with ongoing pain since the injection and was diagnosed by MRI with subdeltoid bursitis. The patient received a short course of prednisone and several months of physical therapy before returning to pain-free function. The primary reason for injection-related subdeltoid bursitis is improper administration. It is a preventable issue, and improved training of healthcare workers on proper vaccine administration may decrease its occurrence.

Abstract
BACKGROUND Shoulder injury related to vaccine administration (SIRVA) is an increasingly recognized complication of improper vaccine administration. Due to the growing number of mandatory workplace vaccination programs, especially for annual influenza vaccine, it is essential that occupational health providers are aware of this condition to improve prevention and/or treatment of this condition when it arises. Therefore, we describe the clinical presentation and course of treatment of five cases of SIRVA that were seen in an employer-based Occupational Health Services Clinic (OHS) after mandatory influenza vaccine administration. METHODS A retrospective chart review was performed for five cases of SIRVA from 2017 to 2019. FINDINGS Five cases met clinical definition of SIRVA as defined by the National Vaccine Injury Compensation Program. All cases were of similar characteristics including gender, age range, and body mass index (BMI). All were treated using multiple modalities including medication, physical therapy, and modified work with eventual resolution of symptoms and full return to work. CONCLUSIONS/APPLICATION TO PRACTICE Awareness of SIRVA is necessary in any occupational setting where vaccines are routinely administered. Avoidance of SIRVA by adhering to proper vaccination technique is crucial, as is awareness of how to recognize and manage the condition in affected employees to limit long-term impairment.

Arthus Reaction as an Adverse Event Following Tdap Vaccination. Vaccines (Basel) 2020; 8:vaccines8030385.

Abstract
Repeat administration of tetanus toxoid-containing vaccines has rarely been associated with Arthus phenomenon, an immune-complex reaction. In the US, since 2013, tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccines (Tdap) have been recommended for administration during each pregnancy. Separately, in 2019, one Tdap was approved for repeat administration in adults in the US. We aimed to describe trends in spontaneously reported Arthus reactions following Tdap in the US and to assess the risk of this phenomenon in persons receiving Tdap repeatedly. We reviewed Arthus reports in the Vaccine Adverse Events Reporting System (VAERS), 1990-2018. Reporting rates were estimated using Tdap doses distributed data. A systematic literature review was conducted in MEDLINE for any Arthus cases reported in Tdap clinical trials and observational studies published between 2000 and 2019. We found 192 Arthus reports in VAERS after any vaccine, of which 36 occurred after Tdap and none were reported during pregnancy. The Arthus reporting rate was estimated at 0.1 per million doses distributed. We identified eight published studies of Tdap administration within five years after a previous dose of tetanus toxoid-containing vaccine; no Arthus cases were reported. We conclude that Arthus reaction following Tdap is extremely rare. Increasing frequency of repeat Tdap administration in adults in the US did not result in a detectable increase in reporting rates of this phenomenon, confirming the favorable safety profile of Tdap.

Abstract
OBJECTIVE Local reactions are the most common vaccine-related adverse event. There is no specific diagnosis code for local reaction due to vaccination. Previous vaccine safety studies used non-specific diagnosis codes to identify potential local reaction cases and confirmed the cases through manual chart review. In this study, a natural language processing (NLP) algorithm was developed to identify local reaction associated with tetanus-diphtheria-acellular pertussis (Tdap) vaccine in the Vaccine Safety Datalink. METHODS Presumptive cases of local reactions were identified among members ≥ 11 years of age using ICD-9-CM codes in all care settings in the 1-6 days following a Tdap vaccination between 2012 and 2014. The clinical notes were searched for signs and symptoms consistent with local reaction. Information on the timing and the location of a sign or symptom was also extracted to help determine whether or not the sign or symptom was vaccine related. Reactions triggered by causes other than Tdap vaccination were excluded. The NLP algorithm was developed at the lead study site and validated on a stratified random sample of 500 patients from five institutions. RESULTS The NLP algorithm achieved an overall weighted sensitivity of 87.9%, specificity of 92.8%, positive predictive value of 82.7%, and negative predictive value of 95.1%. In addition, using data at one site, the NLP algorithm identified 3326 potential Tdap-related local reactions that were not identified through diagnosis codes. CONCLUSION The NLP algorithm achieved high accuracy, and demonstrated the potential of NLP to reduce the efforts of manual chart review in vaccine safety studies.

Role of innate lymphoid cells and dendritic cells in intradermal immunization of the enterovirus antigen. NPJ Vaccines 2019; 4:14. [PMID: 30937186 PMCID: PMC6437170 DOI: 10.1038/s41541-019-0108-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2018] [Accepted: 03/04/2019] [Indexed: 01/04/2023] Open
Abstract
Enterovirus type 71 (EV71) and coxsackievirus A 16 (CA16) are the major pathogens of human hand, foot, and mouth disease (HFMD). In our previous study, intramuscular immunization with the inactivated EV71 vaccine elicited effective immunity, while immunization with the inactivated CA16 vaccine did not. In this report, we focused on innate immune responses elicited by inactivated EV71 and CA16 antigens administered intradermally or intramuscularly. The distributions of the EV71 and CA16 antigens administered intradermally or intramuscularly were not obviously different, but the antigens were detected for a shorter period of time when administered intradermally. The expression levels of NF-κB pathway signaling molecules, which were identified as being capable of activating DCs, ILCs, and T cells, were higher in the intradermal group than in the intramuscular group. Antibodies for the EV71 and CA16 antigens colocalized with ILCs and DCs in skin and muscle tissues under fluorescence microscopy. Interestingly, ILC colocalization decreased over time, while DC colocalization increased over time. ELISpot analysis showed that coordination between DCs and ILCs contributed to successful adaptive immunity against vaccine antigens in the skin. EV71 and/or CA16 antigen immunization via the intradermal route was more capable of significantly increasing neutralizing antibody titers and activating specific T cell responses than immunization via the intramuscular route. Furthermore, neonatal mice born to mothers immunized with the EV71 and CA16 antigens were 100% protected against wild-type EV71 or CA16 viral challenge. Together, our results provide new insights into the development of vaccines for HFMD. Coxsackievirus A 16 (CA16) and enterovirus 71 (EV71) infections are the most common cause of hand-foot-and-mouth diseases. Inactivated virus has been evaluated as potential vaccine for both viruses in animal models, but protection was only achieved for EV71. In this study, led by Qihan Li from the Chinese Academy of Medical Sciences, researchers show that intradermal, as compared to intramuscular immunization, results in an elevated immune response and improved protection from EV71 and CA16 infection in mice. Intradermal vaccination increases interaction of vaccine antigen with dendritic cells and innate lymphoid cells at the site of inoculation, as compared to intramuscular vaccination. Intradermal vaccination furthermore improves the antibody and T cell response and protects mice from infection. However, complete protection of mice from CA16 infection was only achieved after intradermal immunization with a combination of inactivated EV71 and CA16 vaccine, suggesting that further improvements of this vaccine candidate will be necessary.

Abstract
The development of therapeutic cancer vaccines as a means to generate immune reactivity against tumors has been explored since the early discovery of tumor-specific antigens by Georg Klein in the 1960s. However, challenges including weak immunogenicity, systemic toxicity, and off-target effects of cancer vaccines remain as barriers to their broad clinical translation. Advances in the design and implementation of biomaterials are now enabling enhanced efficacy and reduced toxicity of cancer vaccines by controlling the presentation and release of vaccine components to immune cells and their microenvironment. Here, we discuss the rational design and clinical status of several classes of cancer vaccines (including DNA, mRNA, peptide/protein, and cell-based vaccines) along with novel biomaterial-based delivery technologies that improve their safety and efficacy. Further, strategies for designing new platforms for personalized cancer vaccines are also considered.

Abstract
There are 12 billion injections given worldwide every year. For many injections, the intramuscular route is favoured over the subcutaneous route due to the increased vascularity of muscle tissue and the corresponding increase in the bioavailability of drugs when administered intramuscularly. This paper is a review of the variables that affect the success of intramuscular injections and the implications that these success rates have in psychiatry and general medicine. Studies have shown that the success rates of intended intramuscular injections vary between 32 and 52%, with the rest potentially resulting in inadvertent subcutaneous drug deposition. These rates are found to be even lower for certain at-risk populations, such as obese patients and those on antipsychotic medications. The variables associated with an increased risk of injection failure include female sex, obesity, site of injection, and subcutaneous fat depth. New guidelines and methods are needed in order to address this challenge and ensure that patients receive optimum care. Looking forward, the best way to improve the delivery of intramuscular injections worldwide is to develop uniform algorithms or innovative medical devices to confirm or guarantee successful delivery at the bedside.

Comparison of the G and V methods for ventrogluteal site identification: Muscle and subcutaneous fat thicknesses and considerations for successful intramuscular injection. Int J Ment Health Nurs 2018; 27:631-641. [PMID: 28752590 DOI: 10.1111/inm.12346] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2016] [Accepted: 03/15/2017] [Indexed: 11/28/2022]
Abstract
The ventrogluteal site is increasingly recommended for long-acting antipsychotic intramuscular injections; however, it remains infrequently utilized due to nurses' lack of confidence in site identification. The more recent G (geometric) method of ventrogluteal site identification is less subjective and likely more reliable than the V method for successful intramuscular injection outcomes. Knowledge of muscle and subcutaneous fat thicknesses, and the influence of sex and anthropometry on theoretical injection outcome, is necessary to support evidence-based use of the ventrogluteal site. In the presents study, we compared the V and G methods for injection site subcutaneous fat, muscle, and total tissue thicknesses, and theoretical injection outcome (bone injury, intramuscular or subcutaneous), and determined anthropometric predictors of injection outcome. Subcutaneous fat and muscle thicknesses were measured via ultrasound, bilaterally at V and G method sites (28 males, 32 females). Muscle and total tissue were significantly thicker, and successful intramuscular injection significantly more likely, using the G versus V method (75% versus 57%). Females had significantly thicker subcutaneous fat than males at both sites. Even using the G method, 92% of males but only 59% of females, would have a successful intramuscular injection, with remaining females at risk of bone injury (16%) or subcutaneous injection (25%). The G method site is more reliable for successful intramuscular injection, with less risk of bone injury than the V method site. Appropriate needle-length selection is essential for females with a body mass index (BMI) <23 kg m-2 and weight <60 kg (to avoid bone injury), and BMI >30 kg m-2 and hip >90 cm (to avoid subcutaneous injection).

Analysis of adverse events following immunization caused by immunization errors. Rev Bras Enferm 2017; 70:87-95. [PMID: 28226046 DOI: 10.1590/0034-7167-2016-0034] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Accepted: 01/29/2016] [Indexed: 11/21/2022] Open
Abstract
Objective: to analyze adverse events following immunization (AEFI) caused by immunization error in the state of Paraná, Brazil, from 2003 to 2013. Method: this is a descriptive, documental, retrospective, and quantitative research using secondary data from the Adverse Event Following Immunization Information System and the Immunization Program Evaluation System. We included cases confirmed and/or associated with different types of vaccines. For the analysis, we collected frequencies and incidence rates, and used simple linear regression models with Student's t-test. Results: it was observed an AEFI increase due to immunization errors, especially hot subcutaneous abscesses. BCG vaccine had the highest incidence of adverse events and children under one year old were the most affected individuals. Conclusion: the current scenario is worrisome because these are preventable AEFI - injuring patients due to bad vaccination practices - that may undermine the population's confidence, reducing immunization coverage, and the progress in the control of vaccine-preventable diseases.

Abstract
It is becoming increasingly important for clinicians to identify a safer intramuscular (IM) injection site in the deltoid muscle because of possible complications following the vaccine administration of IM injections. We herein examined 4 original IM sites located on the perpendicular line through the mid-acromion to establish a safer IM injection site. Thirty healthy volunteers participated in this study and the distances from our 4 IM sites to some anatomical landmarks on their left arms were measured. Ultrasonography (US) was also performed to measure the thickness of the deltoid muscle and identify the posterior circumflex humeral artery (PCHA) along the course of the axillary nerve. Subcutaneous thickness was measured using 2 methods: measuring the skin thickness with caliper after pinching the skin, and with US. The results obtained revealed that the intersection between the anteroposterior axillary line (the line between the upper end of the anterior axillary line and the upper end of the posterior axillary line) and the perpendicular line from the mid-acromion was the most appropriate site for IM injections because it was distant from the axillary nerve, PCHA, and subdeltoid/subacromial brusa. At this site, depth of needle insertions was 5 mm greater than the subcutaneous thickness at a 90° angle, which was sufficient to penetrate subcutaneous tissue in both sexes. Subcutaneous thickness can be assessed with almost the same accuracy by US or measuring with calipers after pinching the skin. The results of the present study support the improved vaccine practice for safer IM injections.
