Abstract

An online cross-sectional study on COVID-19 vaccination adhesion was conducted in Portugal nine months after vaccination rollout (September–November 2021). Logistic regression was used to identify factors associated with hesitancy to take the COVID-19 vaccine in the community-based survey, “COVID-19 Barometer: Social Opinion”. Hesitancy was 11%; however, of those, 60.5% stated that they intended to take the vaccine. Hesitancy was associated with factors such as lower monthly household income; no intention of taking the flu vaccine this year; perceived reasonable health status; having two or more diseases; low confidence in the health service response; worse perception of the adequacy of anti-COVID-19 government measures; low or no perceived risk of getting COVID-19; feeling agitated, anxious or sad some days; and lack of trust in the safety and efficacy of the vaccines. Confidence in vaccines, namely against COVID-19, is paramount for public health and should be monitored during vaccination rollout. Clear communication of the risks and benefits of vaccination needs improvement to increase adherence and public confidence.
