ABSTRACT
IntroductionIn a multi-center prospective cohort of essential workers, we assessed knowledge, attitudes, and practices (KAP) by vaccine intention, prior SARS-CoV-2 positivity, and occupation, and their impact on vaccine uptake over time. MethodsInitiated in July 2020, HEROES-RECOVER cohort provided socio-demographics and COVID-19 vaccination data. Using follow-up two surveys approximately three months apart, COVID-19 vaccine KAP, intention, and receipt was collected; the first survey categorized participants as reluctant, reachable, or endorsers. ResultsA total of 4,803 participants were included in the analysis. Most (70%) were vaccine endorsers, 16% were reachable, and 14% were reluctant. By May 2021, 77% had received at least one vaccine dose. KAP responses strongly predicted vaccine uptake, particularly positive attitudes about safety (aOR=5.46, 95% CI 1.4-20.8) and effectiveness (aOR=5.0, 95% CI 1.3-19.1). Participants prior SARS-CoV-2 infection were 22% less likely to believe the COVID-19 vaccine was effective compared with uninfected participants (aOR 0.78, 95% CI 0.64-0.96). This was even more pronounced in first responders compared with other occupations, with first responders 42% less likely to believe in COVID-19 vaccine effectiveness (aOR=0.58, 95% CI 0.40-0.84). KAP responses shifted positively, with reluctant and reachable participant scores modestly increasing in positive responses for perceived vaccine effectiveness (7% and 12%, respectively) on the second follow-up survey; 25% of initially reluctant participants received the COVID-19 vaccine. DiscussionOur study demonstrates attitudes associated with COVID-19 vaccine uptake and a positive shift in attitudes over time. First responders, despite potential high exposure to SARS-CoV-2, and participants with a history of SARS-CoV-2 infection were more vaccine reluctant. ConclusionsCOVID-19 vaccine KAP responses predicted vaccine uptake and associated attitudes improved over time. Perceptions of the COVID-19 vaccine can shift over time. Targeting messages about the vaccines safety and effectiveness in reducing SARS-CoV-2 virus infection and illness severity may increase vaccine uptake for reluctant and reachable participants.
