Republican-inclined states exhibit lower COVID-19 vaccination rates, but the association between political inclination and reported vaccine adverse events (AEs) is unexplored.<h4>Objective</h4>To assess whether there is an association between state political inclination and the reporting rates of COVID-19 vaccine AEs.<h4>Design, setting, and participants</h4>This cross-sectional study used the AE reports after COVID-19 vaccination from the Vaccine Adverse Event Reporting System (VAERS) database from 2020 to 2022, with reports after influenza vaccines from 2019 to 2022 used as a reference. These reports were examined against state-level percentage of Republican votes in the 2020 US presidential election.<h4>Exposure</h4>State-level percentage of Republican votes in the 2020 US presidential election.<h4>Main outcomes and measures</h4>Rates of any AE among COVID-19 vaccine recipients, rates of any severe AE among vaccine recipients, and the proportion of AEs reported as severe.<h4>Results</h4>A total of 620 456 AE reports (mean [SD] age of vaccine recipients, 51.8 [17.6] years; 435 797 reports from women [70.2%]; a vaccine recipient could potentially file more than 1 report, so reports are not necessarily from unique individuals) for COVID-19 vaccination were identified from the VAERS database. Significant associations between state political inclination and state AE reporting were observed for all 3 outcomes: a 10% increase in Republican voting was associated with increased odds of AE reports (odds ratio [OR], 1.05; 95% CI, 1.05-1.05; P < .001), severe AE reports (OR, 1.25; 95% CI, 1.24-1.26; P < .001), and the proportion of AEs reported as severe (OR, 1.21; 95% CI, 1.20-1.22; P < .001). These associations were seen across all age strata in stratified analyses and were more pronounced among older subpopulations.<h4>Conclusions and relevance</h4>This cross-sectional study found that the more states were inclined to vote Republican, the more likely their vaccine recipients or their clinicians reported COVID-19 vaccine AEs. These results suggest that either the perception of vaccine AEs or the motivation to report them was associated with political inclination."],"journal":["JAMA network open"],"pagination":["e244177"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC10980960"],"repository":["biostudies-literature"],"pubmed_title":["Reports of COVID-19 Vaccine Adverse Events in Predominantly Republican vs Democratic States."],"pmcid":["PMC10980960"],"pubmed_authors":["Asch DA","Chen Y","Luo C"],"additional_accession":[]},"is_claimable":false,"name":"Reports of COVID-19 Vaccine Adverse Events in Predominantly Republican vs Democratic States.","description":"<h4>Importance</h4>Antivaccine sentiment is increasingly associated with conservative political positions.
