Loran DA, Angelo S, Ryan M. Specialized Vaccine Care for Adverse Events Following Immunization and Impact on Vaccine Hesitancy in the Military Health System. Mil Med 2024; 189:546-550. [PMID: 39160803 DOI: 10.1093/milmed/usae182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 02/08/2024] [Accepted: 03/28/2024] [Indexed: 08/21/2024] Open
Abstract
INTRODUCTION The World Health Organization identified vaccine hesitancy as one of the top 10 threats to global health. Vaccine hesitancy is defined as a delay in acceptance or refusal of vaccination despite the availability of vaccination services. Because vaccine safety concerns are important contributors to hesitancy, people who have experienced adverse events following immunization (AEFI) may be at especially high risk for subsequent vaccine hesitancy. The Defense Health Agency Immunization Healthcare Division (DHA IHD) provides specialized vaccine care to persons who have experienced AEFI. The impact of this specialized vaccine care on subsequent vaccine hesitancy has not been fully explored. MATERIALS AND METHODS A cohort of patients (n= 146) was identified among those who received consultative care from DHA IHD clinicians for AEFI concerns between April 2017 and September 2022. Analyses were restricted to non-uniformed beneficiaries of the Military Health System (MHS). Uniformed beneficiaries of the MHS were excluded from this analysis since vaccination mandates preclude the use of vaccine uptake as a measure of vaccine hesitancy. Outcomes were evaluated by reviewing MHS vaccination records after initial AEFI consultation through January 2023. Vaccine acceptance was considered the inverse of hesitancy, and was defined by: (a) receipt of any subsequent vaccination, (b) receipt of seasonal influenza vaccine, (c) receipt of subsequent doses of the AEFI-associated vaccine, if clinically recommended, and (d) receipt of COVID-19 vaccine. RESULTS A diverse group of patients with a wide range of AEFI concerns received specialized vaccine care from DHA IHD clinicians during this period. Among the cohort, 78% of patients received any subsequent vaccination, 55.2% received seasonal influenza vaccine, 57.8% received a subsequent dose of their AEFI-associated vaccine when the vaccine was clinically recommended, and 48.9% received COVID-19 vaccine. The proportion of patients who received influenza vaccine exceeded the reported rate of influenza vaccine uptake by the general population during this time period. CONCLUSION Specialized vaccine care after AEFI concerns was associated with relatively high acceptance of subsequent vaccinations. The experiences of DHA IHD clinicians, in providing specialized vaccine care to AEFI patients, may serve as a model for other organizations that are working to reduce vaccine hesitancy, even beyond the MHS.

Abstract
The U.S. COVID-19 vaccination program, which commenced in December 2020, has been instrumental in preventing morbidity and mortality from COVID-19 disease. Safety monitoring has been an essential component of the program. The federal government undertook a comprehensive and coordinated approach to implement complementary safety monitoring systems and to communicate findings in a timely and transparent way to healthcare providers, policymakers, and the public. Monitoring involved both well-established and newly developed systems that relied on both spontaneous (passive) and active surveillance methods. Clinical consultation for individual cases of adverse events following vaccination was performed, and monitoring of special populations, such as pregnant persons, was conducted. This report describes the U.S. government's COVID-19 vaccine safety monitoring systems and programs used by the Centers for Disease Control and Prevention, the U.S. Food and Drug Administration, the Department of Defense, the Department of Veterans Affairs, and the Indian Health Service. Using the adverse event of myocarditis following mRNA COVID-19 vaccination as a model, we demonstrate how the multiple, complementary monitoring systems worked to rapidly detect, assess, and verify a vaccine safety signal. In addition, longer-term follow-up was conducted to evaluate the recovery status of myocarditis cases following vaccination. Finally, the process for timely and transparent communication and dissemination of COVID-19 vaccine safety data is described, highlighting the responsiveness and robustness of the U.S. vaccine safety monitoring infrastructure during the national COVID-19 vaccination program.

Abstract
Hypertrichosis is described as an increased hair growth on any part or over whole body in comparison to persons of the same age, sex, and race which is independent of androgen excess. It may be localized and generalized or alternatively acquired and congenital forms. The acquired localized hypertrichosis has been associated with various causes including local trauma, chronic irritation, inflammation, occlusion by cast, and drugs. Here, we report a case of 2½-month-old healthy infant presenting with localized area of hypertrichosis over anterolateral aspect of the left thigh which was confined to the site of vaccination.

Abstract
Background A prime-boost vaccination regimen with ALVAC-HIV (vCP1521) administered intramuscularly at 0, 4, 12, and 24 weeks and gp120 AIDSVAX B/E at 12 and 24 weeks demonstrated modest efficacy of 31.2% for prevention of HIV acquisition in HIV-uninfected adults participating in a community-based efficacy trial in Thailand. Methodology/Principal Findings Reactogenicity was recorded for 3 days following vaccination. Adverse events were monitored every 6 months for 3.5 years, during which pregnancy outcomes were recorded. Of the 16,402 volunteers, 69% of the participants reported an adverse event any time after the first dose. Only 32.9% experienced an AE within 30 days following any vaccination. Overall adverse event rates and attribution of relatedness did not differ between groups. The frequency of serious adverse events was similar in vaccine (14.3%) and placebo (14.9%) recipients (p = 0.33). None of the 160 deaths (85 in vaccine and 75 in placebo recipients, p = 0.43) was assessed as related to vaccine. The most common cause of death was trauma or traffic accident. Approximately 30% of female participants reported a pregnancy during the study. Abnormal pregnancy outcomes were experienced in 17.1% of vaccine and 14.6% (p = 0.13) of placebo recipients. When the conception occurred within 3 months (estimated) of a vaccination, the majority of these abnormal outcomes were spontaneous or elective abortions among 22.2% and 15.3% of vaccine and placebo pregnant recipients, respectively (p = 0.08). Local reactions occurred in 88.0% of vaccine and 61.0% of placebo recipients (p<0.001) and were more frequent after ALVAC-HIV than AIDSVAX B/E vaccination. Systemic reactions were more frequent in vaccine than placebo recipients (77.2% vs. 59.8%, p<0.001). Local and systemic reactions were mostly mild to moderate, resolving within 3 days. Conclusions/Significance The ALVAC-HIV and AIDSVAX B/E vaccine regimen was found to be safe, well tolerated and suitable for potential large-scale use in Thailand.

ALLERGY, ASTHMA, AND CLINICAL IMMUNOLOGY : OFFICIAL JOURNAL OF THE CANADIAN SOCIETY OF ALLERGY AND CLINICAL IMMUNOLOGY 2010; 6:26.

Abstract
Despite over a century of clinical use and a well-documented record of efficacy and safety, a growing minority in society questions the validity of vaccination and fear that this common public health intervention is the root-cause of severe health problems. This article questions whether growing public anti-vaccine sentiments might have the potential to spill-over into other therapies distinct from vaccination, namely allergen-immunotherapy. Allergen-immunotherapy shares certain medical vernacular with vaccination (e.g., allergy shots, allergy vaccines), and thus may become "guilty by association" due to these similarities. Indeed, this article demonstrates that anti-vaccine websites have begun unduly discrediting this allergy treatment regimen. Following an explanation of the anti-vaccine movement, the article aims to provide guidance on how clinicians can respond to patient fears towards allergen-immunotherapy in the clinical setting. This guide focuses on the provision of reliable information to patients in order to dispel misconceived associations between vaccination and allergen-immunotherapy, and the discussion of the risks and benefits of both therapies in order to assist patients in making autonomous decisions about their choice of allergy treatment.

Mari A. Is there a causative role for tetanus toxoid vaccination in the development of allergy-like symptoms and in the increasing prevalence of atopic diseases? Med Hypotheses 2004; 63:875-86. [PMID: 15488663 DOI: 10.1016/j.mehy.2004.04.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2004] [Accepted: 04/20/2004] [Indexed: 12/21/2022]
Abstract
Allergic diseases are a worldwide health problem. They mainly affect people living in developed countries where an increasing prevalence of allergy symptoms has been recorded in the last 20-30 years. The cause of this increase is still disputed, and, among others, the "hygiene hypothesis" supported the concept that relevant changes in lifestyle could have a relationship with the phenomenon. More recently the recorded parallel increase in autoimmune diseases has suggested to consider the "hygiene hypothesis" as a cause of a more general disregulation of the immune system leading to both allergy and to autoimmunity. Here are reported a series of observations, evidence, and data from the literature leading to a different hypothesis. The key points are: (1) the presence of two subsets of patients having allergy symptoms based on an IgE-mediated mechanism or not; (2) the positive results obtained with the autologous serum skin test in either cutaneous or respiratory affected subjects, mainly in children and adult females; (3) the presence of IgG autoantibodies against the alpha-chain of the high affinity IgE receptor (FcepsilonRIalpha) in non-IgE-mediated urticaria and even in respiratory subjects; (4) the cross-reactivity between epitopes of the tetanus toxoid molecule and the FcepsilonRIalpha detected by means of an alpha-chain affinity purified IgG fraction; (5) the positive skin reactivity obtained using IgG anti-tetanus toxoid preparations in allergic and non-allergic volunteers. The presence of IgG autoantibodies actively generated by the population-based vaccination with tetanus toxoid could induce both mediator release from activated mast cell and Th2 cytokine production early in life. There are epidemiological evidences that tetanus toxoid vaccination could be linked with an increased tendency to have allergy symptoms. The different epidemiological distribution of non-IgE-mediated symptoms, mainly affecting young infants would be in agreement with the present hypothesis. The prevalent mother-to-child relationship in terms of risk for allergy symptoms could be explained with the trans-placenta transfer of IgG. A similar transfer could also take place through the mother milk during breast feeding. It may thus be hypothesized that the increased prevalence of allergic diseases could be caused by the generalized tetanus toxoid immunization procedure, progressively extended to most of the countries worldwide in the last 30-40 years. Both the induction of non-IgE-mediated symptoms caused by the mast cell activation via the anti-FcepsilonRIalpha IgG and the long lasting Th2 inflammation of affected tissues would be the inducing mechanisms. This hypothesis would re-configure part of the allergic diseases as a Th2 phenotypic expression of an autoimmune disease.
