The main objective of this study was to examine the association between COVID-19 information search activities and vaccination intention.


Cross-sectional data were collected using online surveys. Independent variables included COVID-19 information search on the (1) science of viral effects of COVID-19 on the body, (2) origin of COVID-19, (3) symptoms and outcomes, (4) transmission and prevention, (5) future outbreak, and (6) policies/procedures to follow. The outcome variable was vaccination intention. A multivariable regression analysis was conducted.


Participants (N = 501) had a mean age of 32.44 ± 11.94 years, were 55.3% female, and 67.9% were white. Most COVID-19 information searches were on symptoms and outcomes (77.7%) and policies/procedures to follow (69.9%). Intention to vaccinate against COVID-19 was higher among participants who searched for information on the science of viral effects of COVID-19 on the body (β = 0.23, 95% CI: 0.03-0.43; P = 0.03) and policies/procedures to follow (β = 0.24, 95% CI: 0.03-0.41; P = 0.02).


People who searched for information about (1) the science of viral effects of COVID-19 and (2) policies/procedures recommendations also reported higher vaccination intention. Risk communication seeking to increase vaccination should meet the consumers’ information demand by prioritizing the scientific rationale for COVID-19 vaccination and by clarifying what policies/procedures are recommended.
