Willingness to vaccinate against COVID-19 in the US: Longitudinal evidence from a nationally representative sample of adults from April–October 2020

INTRODUCTION: Vaccines against COVID-19 have been developed in unprecedented time. However, the effectiveness of any vaccine is dictated by the proportion of the population willing to be vaccinated. In this observational population-based study we examined intentions to be vaccinated against COVID-19...

description INTRODUCTION: Vaccines against COVID-19 have been developed in unprecedented time. However, the effectiveness of any vaccine is dictated by the proportion of the population willing to be vaccinated. In this observational population-based study we examined intentions to be vaccinated against COVID-19 over the course of the pandemic. METHODS: We analyzed longitudinal data from a nationally representative sample of 7,547 US adults enrolled in the Understanding America Study (UAS). Participants reporting being willing, undecided and unwilling to get vaccinated against coronavirus across 13 assessments conducted from April-October, 2020. Public attitudes to vaccination against the coronavirus were also assessed. RESULTS: Willingness to vaccinate declined from 71% in April to 53.6% in October. This was explained by an increase in the percentage of participants undecided about vaccinating (from 10.5% to 14.4%) and the portion of the sample unwilling to vaccinate (from 18.5% to 32%). The population subgroups most likely to be undecided/unwilling to vaccinate were those without a degree (undecided: RRR=2.47, 95% CI: 2.04–3.00; unwilling: RRR=1.92, 95% CI: 1.67–2.20), Black participants (undecided: RRR=2.18, 95% CI: 1.73–2.74; unwilling: RRR=1.98, 95% CI: 1.63–2.42), and females (undecided: RRR=1.41, 95% CI: 1.20–1.65; unwilling: RRR=1.29, 95% CI: 1.14–1.46). Those aged 65+, those on high incomes, and other race/ethnicity participants were least likely to be undecided or unwilling to vaccinate. Concerns about potential side effects of a vaccine were common. CONCLUSIONS: Intentions to be vaccinated against coronavirus have declined rapidly during the pandemic and close to half of Americans are undecided or unwilling to be vaccinated.
