Abstract
The safety of human papillomavirus (HPV) vaccines, one of the major challenges to public vaccination, has been controversial. This study assessed the adverse reactions of 9-valent HPV (9vHPV) vaccines. This open-label, observational, multi-center, post-marketing study assessed the safety of 9vHPV administered according to local clinical practice. All post-marketing adverse events (AEs) reports received between December 2019 and November 2021 in Chongqing were analyzed. A total of 1000 individuals aged 16-26 years provided safety data post-vaccination; The most common AEs (60.1%) experienced by 9vHPV vaccine recipients were vaccination-site AEs (pain, swelling, induration) and non-vaccination-site AEs (dizzy, weak, fever). Vaccination-site AEs most were mild-to-moderate in intensity. Discontinuations and HPV 9-related serious AEs were rare (0.3% and 0.0%, respectively). Eight SAEs were reported during the study but none were considered as related to the study vaccine. The 9vHPV vaccine was generally well tolerated in subjects aged 16-26 years; Vaccination-site AEs were more common with 9vHPV.

Real-Life Safety Profile of the 9-Valent HPV Vaccine Based on Data from the Puglia Region of Southern Italy. Vaccines (Basel) 2022; 10:vaccines10030419. [PMID: 35335051 PMCID: PMC8948997 DOI: 10.3390/vaccines10030419] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 03/01/2022] [Accepted: 03/07/2022] [Indexed: 11/16/2022] Open
Abstract
Human Papillomavirus (HPV) is responsible for epithelial lesions and cancers in both males and females. The latest licensed HPV vaccine is Gardasil-9®, a 9-valent HPV vaccine which is effective not only against the high-risk HPV types, but also against the ones responsible for non-cancerous lesions. This report describes adverse events following Gardasil-9® administration reported in Puglia, southern Italy, from January 2018 to November 2021. This is a retrospective observational study. Data about the adverse events following immunization (AEFIs) with Gardasil-9® were collected from the Italian Drug Authority database. AEFIs were classified as serious or non-serious accordingly to World Health Organization guidelines, and serious ones underwent causality assessment. During the study period, 266,647 doses of 9vHPVv were administered in Puglia and 22 AEFIs were reported, with a reporting rate (RR) of 8.25 per 100,000 doses. The most reported symptoms were neurological ones (7/22). A total of 5 (22.7%) AEFIs were classified as serious, and 2 of these led to the patient’s hospitalization. In one case, permanent impairment occurred. Following causality assessment, only 2 out of 5 serious AEFIs were deemed to be consistently associated with the vaccination (RR: 0.750 per 100,000 doses). The data gathered in our study are similar to the pre-licensure evidence as far as the nature of the AEFIs is concerned. The reporting rate, though, is far lower than the ones described in clinical trials, likely due to the different approach to data collection: in our study, data were gathered via passive surveillance, while pre-marketing studies generally employ active calls for this purpose. Gardasil-9®’s safety profile appears to be favorable, with a low rate of serious adverse events and a risk/benefits ratio pending for the latter.

BMC Womens Health 2022; 22:46. [PMID: 35197068 PMCID: PMC8864209 DOI: 10.1186/s12905-022-01625-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 02/08/2022] [Indexed: 12/18/2022] Open
Abstract
Objective To investigate the effect of a web-based educational intervention on changing female college students’ willingness and uptake of human papillomavirus (HPV) vaccines, and factors associated with HPV vaccination acceptance in Western and Northern China. Methods A web-based cluster randomized controlled trial was conducted in Western and Northern China from February to May 2020. A total of 967 female freshmen were recruited from two universities through convenience sampling, stratified sampling (liberal arts or sciences), and cluster sampling. Eligible students were randomized into intervention and control group with a 1:1 allocation ratio. The intervention group received seven days of web-based health education regarding HPV and HPV vaccines, whereas the control group received non-HPV-related materials. All students were asked to complete a post-intervention questionnaire to measure their awareness, uptake, and willingness to receive HPV vaccination at 7-day and one-month intervals. The chi-square test and Student’s t-test were employed to examine the differences between the intervention and control groups for categorical and continuous data. Logistic regressions were used to analyze factors associated with vaccination intentions. Results Nine hundred forty-six female freshmen aged 18.99 ± 0.63 years were enrolled in the study, with 532 in the intervention group and 414 in the control group. Prior to the intervention, 63.8%, 66.3%, and 60.8% of students had heard of HPV, HPV-related diseases, and HPV vaccines, respectively. Only 2.2% of students reported being vaccinated, but 33.0% were willing to be vaccinated against HPV. After seven days of education, students in the intervention group exhibited higher awareness (p < 0.001) and knowledge scores (5.13 ± 1.23 vs. 3.10 ± 1.99, p < 0.001) than those in the control group. Similarly, in the intervention groups, willingness to be vaccinated against HPV was significantly higher than in the control groups (p < 0.001). The high cost (57.7%) and concerns about adverse events (56.0%) were the main reasons female college students did not accept HPV vaccines. School location in urban areas, parents’ higher education backgrounds, history of HPV vaccination counseling, history of sexual behavior, and having heard of HPV vaccines were associated with a higher willingness to be vaccinated. Conclusion Female college students’ HPV vaccination uptake is insufficient, and they have minimal detailed knowledge about HPV and its vaccines. Web-based health education on HPV vaccines is an easy, feasible, and effective way to improve the awareness and acceptance of HPV vaccination among female college students, but it has limited effect on HPV vaccination uptake.

Hineno A, Ikeda SI. A Long-Term Observation on the Possible Adverse Effects in Japanese Adolescent Girls after Human Papillomavirus Vaccination. Vaccines (Basel) 2021; 9:vaccines9080856. [PMID: 34451981 PMCID: PMC8402449 DOI: 10.3390/vaccines9080856] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 07/25/2021] [Accepted: 07/30/2021] [Indexed: 12/01/2022] Open
Abstract
In Japan, a significant number of adolescent females noted unusual symptoms after receiving the human papillomavirus (HPV) vaccination, of which the vast majority of them were initially diagnosed with psychiatric illnesses because of the absence of pathologic radiological images and specific abnormalities in laboratory test results. Later these symptoms were thought to be adverse effects of HPV vaccination. However, a causal link between HPV vaccination and the development of these symptoms has not been demonstrated. Between June 2013 and March 2021, we examined 200 patients who noted various symptoms after HPV vaccination. In total, 87 were diagnosed with HPV vaccination-related symptoms based on our proposed diagnostic criteria. The clinical histories of these 87 patients were analyzed. The age at initial vaccination ranged from 11 to 19 years old (mean ± SD: 13.5 ± 1.5 years old), and the age at the first appearance of symptoms ranged from 12 to 20 years old (mean ± SD: 14.3 ± 1.6 years old). The patients received an initial HPV vaccine injection between May 2010 and May 2013, but the first affected patient developed symptoms in October 2010, and the last affected developed symptoms in October 2015. A cluster of patients with a post-HPV vaccination disorder has not appeared in Japan during the last five years. Our study shows that, in Japan, the period of HPV vaccination considerably overlapped with that of a unique post-HPV vaccination disorder development. This disorder appears as a combination of orthostatic intolerance, chronic regional pain syndrome, and cognitive dysfunction, but its exact pathogenesis remains unclear.

Abstract
The aim of this study was to describe the distribution of human papillomavirus (HPV) genotypes among cervical cancers and pre-cancers in Shaanxi province of western China. A total of 17,341 women who were screened for cervical cancer from January 2014 to December 2016, using HPV genotyping and ThinPrep cytologic test were included. The prevalence and attribution of HPV genotypes were stratified by cervical lesion and age group. Of the subjects, 26.3% were infected with HPV, 28.0% of whom had multiple infections. The crude HPV prevalence increased from atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL, 64.3%) to high-grade squamous intraepithelial lesions (HSIL, 79.8%) and to invasive cervical cancer (ICC, 89.7%, P < 0.001). The three most prevalent genotypes were HPV 16 (8.0%), 58 (4.2%), and 52 (4.0%), and HPV 16, 31 and 33 were positively correlated with increased severity of cervical lesions. Additionally, the divalent vaccine genotypes HPV 16 and 18 accounted for 68.2% of ICC cases. Although 78.5% of ICC and 60.3% of HSIL cases were attributed to 9-valent vaccine genotypes, the other genotypes not covered by any vaccine still resulted in increases in coverage, with 1.5% for ICC, 5.3% for HSIL, and 13.5% for ASCUS/LSIL. HPV prevalence in western China was consistent with other regions of China. Early vaccination with 9-valent HPV vaccine is recommended in this locality for females younger than 26 years with no prior infection, while divalent the vaccine is more appropriate for women between 26 and 45 years, considering the efficacy, safety and cost-effectiveness of vaccines.

Abstract
T cells are often referred to as the 'guided missiles' of our immune system because of their capacity to traffic to and accumulate at sites of infection or disease, destroy infected or mutated cells with high specificity and sensitivity, initiate systemic immune responses, sterilize infections, and produce long-lasting memory. As a result, they are a common target for a range of cancer immunotherapies. However, the myriad of challenges of expanding large numbers of T cells specific to each patient's unique tumor antigens has led researchers to develop alternative, more scalable approaches. Biomaterial platforms for expansion of antigen-specific T cells offer a path forward towards broadscale translation of personalized immunotherapies by providing "off-the-shelf", yet modular approaches to customize the phenotype, function, and specificity of T cell responses. In this review, we discuss design considerations and progress made in the development of ex vivo and in vivo technologies for activating antigen-specific T cells, including artificial antigen presenting cells, T cell stimulating scaffolds, biomaterials-based vaccines, and artificial lymphoid organs. Ultimate translation of these platforms as a part of cancer immunotherapy regimens hinges on an in-depth understanding of T cell biology and cell-material interactions.

Abstract
INTRODUCTION Anthroposophic medicine is a form of integrative medicine that originated in Europe but is not well known in the US. It is comprehensive and heterogenous in scope and remains provocative and controversial in many academic circles. Assessment of the nature and potential contribution of anthroposophic medicine to whole person care and global health seems appropriate. METHODS Because of the heterogenous and multifaceted character of anthroposophic medicine, a narrative review format was chosen. A Health Technology Assessment of anthroposophic medicine in 2006 was reviewed and used as a starting point. A Medline search from 2006 to July 2020 was performed using various search terms and restricted to English. Books, articles, reviews and websites were assessed for clinical relevance and interest to the general reader. Abstracts of German language articles were reviewed when available. Reference lists of articles and the author's personal references were also consulted. RESULTS The literature on anthroposophic medicine is vast, providing new ways of thinking, a holistic view of the world, and many integrating concepts useful in medicine. In the last ∼20 years there has been a growing research base and implementation of many anthroposophical concepts in the integrated care of patients. Books and articles relevant to describing the foundations, scientific status, safety, effectiveness and criticisms of anthroposophic medicine are discussed. DISCUSSION An objective and comprehensive analysis of anthroposophic medicine finds it provocative, stimulating and potentially fruitful as an integrative system for whole person care, including under-recognized life processes and psychospiritual aspects of human beings. It has a legitimate, new type of scientific status as well as documented safety and effectiveness in some areas of its multimodal approach. Criticisms and controversies of anthroposophic medicine are often a result of lack of familiarity with its methods and approach and/or come from historically fixed ideas of what constitutes legitimate science.

Abstract
Background Studies have shown that thiamine intake is associated with cervical cancer, but the relationship between thiamine and HPV infection remains unclear. In the present study, we used the National Health and Nutrition Examination Survey (NHANES) database to investigate whether HPV infection was associated with thiamine intake. Material/Methods A total of 13 471 women ages 18–59 years were selected from the NHANES database from 2003 to 2016. Using thiamine intake as the independent variable, HPV infection as the dependent variable, and sociodemographic data and other data as the covariates, we analyzed the relationship between thiamine and HPV infection by conducting a weighted logistic regression model in a cross-sectional research design. Results The two-piecewise linear model indicated the inflection point of thiamine intake was 2.07 mg. On the left side of the inflection point, the difference in the thiamine intake of log2 conversion was related to the difference of 0.82 in HPV infection, which means that the increase of every 1 unit increase in thiamine intake is associated with the decrease of the HPV infection by 18%. On the right side of the inflection point, we did not observe a correlation between HPV infection and thiamine intake. Conclusions Thiamine intake is negatively correlated with HPV infection. Intake of an appropriate amount of thiamine can prevent HPV infection. The best preventive effect can be achieved when the intake is about 2 mg, and excessive intake will not increase the preventive effect.

Abstract
BACKGROUND This objective of this umbrella review was to summarize the evidence on safety, efficacy, and effectiveness of human papillomavirus (HPV) vaccines in the general population. METHODS The authors conducted a literature search and selected systematic reviews if they were published from January 2006 through November 2018, included randomized controlled trials or observational studies, related to the general population, and evaluated HPV vaccine-related clinical outcomes. The authors independently and in duplicate screened literature, extracted data, and appraised reviews using AMSTAR 2, a critical appraisal tool for systematic reviews. RESULTS The authors selected 30 systematic reviews that included male and female participants aged 9 through 76 years from multiple countries. Reviews evaluated postvaccine seroconversion, HPV infection rates, precancerous or benign lesions, and adverse events; none of the researchers reported on oral or oropharyngeal lesions. Results from the reviews showed that, compared with those who received a placebo or non-HPV-type vaccine, HPV-vaccinated participants had statistically significantly higher rates of seroconversion and local adverse events, statistically significantly lower rates of HPV infection and condylomata lesions, and decreased rates of HPV-related precancerous lesions, which did not always attain statistical significance. CONCLUSIONS Systematic reviews have found evidence that the available HPV vaccines are safe, effective, and efficacious against vaccine-type HPV infection and HPV-associated cellular changes, including precancerous and benign lesions. PRACTICAL IMPLICATIONS Dentists may use this resource to better understand the literature on the potential harms and benefits of HPV vaccination.

Abstract
In spite of the demonstrated benefits, the question of HPV massive vaccination is still subject to intense discussions and controversies. The protection against cancer is still unproven and need more time to be accurate about the quantification of the decrease in cervical cancer. The analysis of HPV vaccine relevance is very complex due to several overlapped levels to be considered. The authors analyze many of the ethical, sociological, economic, political and finally scientific issues involved. The population trust in vaccines has been affected owing to dubious practices of many pharmaceutical companies. Faced with this manipulation of information on a worldwide scale, general practitioners have organized themselves to fight this uncertainty. Quaternary prevention, a concept supported by the World Organization of Family doctors, advocates the application of ethically acceptable procedures in health care. This opinion article addresses some of the multiple dimensions involved to encourage reflection on this issue.

Abstract
Fibromyalgia is a disorder characterized by chronic widespread pain and non-pain symptoms, such as fatigue, dysautonomia, and cognitive and sleep disturbances. Its pathogenesis and treatment continue to be the subject of debate. We highlight the role of three mechanisms-autoimmunity, neuroinflammation, and small fiber neuropathy-in the pathogenesis of the disease. These mechanisms are shown to be closely interlinked (also on a molecular level), and the review considers the implementation of this relationship in the search for therapeutic options. We also pay attention to chronic fatigue syndrome, which overlaps with fibromyalgia, and propose a concept of "autoimmune hypothalamopathy" for its pathogenesis. Finally, we analyze the molecular mechanisms underlying the neuroinflammatory background in the development of adverse events following HPV vaccination and suggesting neuroinflammation, which could exacerbate the development of symptoms following HPV vaccination (though this is hotly debated), as a model for fibromyalgia pathogenesis.

[PMID: 31788119 PMCID: PMC6865731 DOI: 10.3892/ol.2019.11007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Accepted: 08/30/2019] [Indexed: 01/05/2023] Open
Abstract
The aim of the present study was to analyze the differences in zinc finger of the cerebellum 1 (ZIC1) expression between cervical cancer tissue, precancer tissue and normal cervical tissue to determine its clinicopathological and prognostic value in cervical squamous cell carcinoma (CSCC). Reverse transcription-quantitative PCR was used to determine the mRNA expression levels of ZIC1 in 569 fresh-frozen biopsy tissues, and immunohistochemistry was performed to detect ZIC1 protein expression in 80 CSCC tissues and 320 cervical intraepithelial neoplasia (CIN) grade III samples. The association of ZIC1 expression with the clinicopathological characteristics of CSCC was then analyzed using Cox regression analysis, and Kaplan-Meier curves were used to analyze the prognostic value. The level of ZIC1 mRNA expression in CSCC was significantly lower compared with normal cervical tissues and CIN I–III tissues (P<0.001). There was a negative correlation between ZIC1 immunoreactivity score (IRS) in CSCC tissue and adjacent noncancerous tissue (R=−0.279; P=0.012); the mean IRS of ZIC1 in CSCC tissue was 5.36±3.48, which was significantly lower compared with the corresponding adjacent noncancerous tissues (11.31±5.68; P<0.001) and CIN III samples (10.42±1.54; P<0.001). In addition, expression of ZIC1 was negatively associated with International Federation of Gynecology and Obstetrics (FIGO) stage (P=0.027) and lymph node metastasis (P<0.001). In Cox regression analysis, ZIC1 expression [hazard ratio (HR), 0.61; 95% confidence interval (CI), 0.40–0.92; P=0.018), FIGO staging (HR, 3.55; 95% CI, 2.35–5.37; P<0.001) and lymph node metastasis (HR, 2.50; 95% CI, 1.62–3.86; P<0.001) were three independent prognostic factors of overall survival. Furthermore, ZIC1 expression was also associated with disease-free survival (P=0.003). These results suggest that ZIC1 expression in CSCC may be lower than in normal cervical tissues or CIN tissues, and high expression of ZIC1 may be negatively associated with FIGO stage and lymph node metastasis. Therefore, ZIC1 may be a promising biomarker for the prognosis of CSCC.

Abstract
This article reviews the case series reported from several countries describing patients with suspected severe side effects to the HPV vaccines. The described symptom clusters are remarkably similar and include disabling fatigue, headache, widespread pain, fainting, gastrointestinal dysmotility, limb weakness, memory impairment episodes of altered awareness, and abnormal movements. This constellation of symptoms and signs has been labeled with different diagnoses such as complex regional pain syndrome (CRPS), postural orthostatic tachycardia syndrome (POTS), small fiber neuropathy (SFN), myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), or fibromyalgia. It is known that autoimmunity and autoantibodies are present in a subset of patients with CRPS, POTS, SFN, ME/CFS, and fibromyalgia. This article proposes that vaccine-triggered, immune-mediated autonomic dysfunction could lead to the development of de novo post-HPV vaccination syndrome possibly in genetically susceptible individuals. Being cognizant that a temporal relationship between vaccination and symptom onset does not necessarily equate to causality, mounting evidence of case series calls for well-designed case-control studies to determine the prevalence and possible causation between these symptom clusters and HPV vaccines. Since personalized medicine is gaining momentum, the use of adversomics and pharmacogenetics may eventually help identify individuals who are predisposed to HPV vaccine adverse events.

Abstract
Cervical cancer incidence and mortality have decreased in high-income countries, but low- and middle-income countries continue to bear a significant burden from the disease. Human papillomavirus (HPV) vaccines are a promising alternative for disease control; however, their introduction is slow in settings with greater need. We conducted a review of HPV vaccine efficacy and effectiveness reported in clinical trials and population-based studies. Efficacy of HPV vaccines is close to 100% when using a three-dose schedule in HPV-negative young women (<25 years old) for protection against persistent infection and HPV vaccine-type associated pre-cancerous lesions. Furthermore, sustained protection for up to 12 years of follow-up has been demonstrated; cross-protection against non-vaccine types is particularly observed for the bivalent vaccine, and preliminary data regarding impact on invasive cancer have emerged. Given its lower efficacy, catch-up vaccination beyond 19 years of age and proposals for vaccinating adult women deserve careful evaluation in accurately designed studies and economic analyses. Despite positive results regarding immunogenicity and post-hoc analysis for cervical intra-epithelial neoplasia in clinical trials, population-based data for prime and booster two-dose schedules are not available. Evaluation of vaccine safety from surveillance systems in immunization programs that have already distributed more than 270 million doses found no association of HPV vaccination with serious side effects. The introduction of HPV vaccination in national immunization programs remains the main challenge in tackling the burden of cervical cancer (up to 2018, only 89 countries have introduced vaccination worldwide, and most of these are high-income countries). Access models and technical capacity require further development to help low- and middle-income countries to increase the pace of vaccine delivery. Alternative approaches such as one-dose schedules and vaccination at younger ages may help reduce the programmatic and economic challenges to adolescent vaccination.

Myalgia and chronic fatigue syndrome following immunization: macrophagic myofasciitis and animal studies support linkage to aluminum adjuvant persistency and diffusion in the immune system. Autoimmun Rev 2019; 18:691-705.

Abstract
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a multifactorial and poorly undersood disabling disease. We present epidemiological, clinical and experimental evidence that ME/CFS constitutes a major type of adverse effect of vaccines, especially those containing poorly degradable particulate aluminum adjuvants. Evidence has emerged very slowly due to the multiplicity, lack of specificity, delayed onset, and frequent medical underestimation of ME/CFS symptoms. It was supported by an epidemiological study comparing vaccinated vs unvaccinated militaries that remained undeployed during Gulf War II. Affected patients suffer from cognitive dysfunction affecting attention, memory and inter-hemispheric connexions, well correlated to brain perfusion defects and associated with a stereotyped and distinctive pattern of cerebral glucose hypometabolism. Deltoid muscle biopsy performed to investigate myalgia typically yields macrophagic myofasciitis (MMF), a histological biomarker assessing longstanding persistency of aluminum agglomerates within innate immune cells at site of previous immunization. MMF is seemingly linked to altered mineral particle detoxification by the xeno/autophagy machinery. Comparing toxicology of different forms of aluminum and different types of exposure is misleading and inadequate and small animal experiments have turned old dogma upside down. Instead of being rapidly solubilized in the extracellular space, injected aluminum particles are quickly captured by immune cells and transported to distant organs and the brain where they elicit an inflammatory response and exert selective low dose long-term neurotoxicity. Clinical observations and experiments in sheep, a large animal like humans, confirmed both systemic diffusion and neurotoxic effects of aluminum adjuvants. Post-immunization ME/CFS represents the core manifestation of "autoimmune/inflammatory syndrome induced by adjuvants" (ASIA).

Abstract
Several groups of investigators have described the presence of small fiber neuropathy in fibromyalgia patients. This writing discusses how this new finding could renovate fibromyalgia concept, diagnosis, and treatment. Predominant rheumatology thinking proposes fibromyalgia as a "centralized pain syndrome." An alternative hypothesis views fibromyalgia as a stress-related dysautonomia with neuropathic pain features. Dorsal root ganglia may be the key autonomic-nociceptive short-circuit sites. The recent recognition of small fiber neuropathy in a large subgroup of fibromyalgia patients reinforces the dysautonomia-neuropathic hypothesis and validates fibromyalgia pain. These new findings support fibromyalgia as a primarily neurological entity, nevertheless, rheumatologist will likely remain the best equipped specialist to diagnose fibromyalgia and differentiate it from other multi-symptomatic rheumatic syndromes. Skin biopsy and corneal confocal microscopy will probably become useful fibromyalgia diagnostic tests. Dorsal root ganglia sodium channel blockers are potential fibromyalgia analgesic medications. Subgroups of young girls with "autoimmune neuropathic fibromyalgia" may respond to immunoglobulin therapy. Multimodal intervention directed to regain autonomic nervous system resilience will likely remain the cornerstone for fibromyalgia therapy.

Abstract
Data from the Vaccine Adverse Event Reporting System (VAERS) contain spontaneously reported adverse events (AEs) from the public. It has been a major data source for detecting AEs and monitoring vaccine safety. As one major limitation of spontaneous surveillance systems, the VAERS reports by themselves sometimes do not provide enough information to answer certain research questions. For example, patient level demographics are very limited in VAERS due to the protection of patient privacy, such that investigation of differential AE rates across race/ethnicity groups cannot be conducted using VAERS data only. For many vaccines, racial and ethnical difference in immune responses has been found in studies based on racially diverse cohorts. It is of great interest to characterize the differential AE rates by race and ethnicity groups for vaccines. In this study, we propose a novel statistical method to integrate VAERS data with data from other resources for vaccine pharmacovigilance research. Specifically, we integrate VAERS data with CDC survey data of vaccine coverage and U.S. census data of race/ethnicity distribution to quantify differential AE rates by race/ethnicity groups for HPV vaccine. We utilize the difference of race/ethnicity distributions across U.S. states to investigate the association between AE reporting rate and race/ethnicity groups at the population level. We identify 9 AEs with significantly different reporting rates between non-Hispanic White females and other race/ethnicity groups.
