Who is up for COVID vaccines? All across the world, men, people who trust science, & people who worry about COVID more likely to say yes to a vaccine--

Our new study in @BMJ_Open, surveying 20,000 people across 12 countries in 2020.

We find that men, people more #trusting of expertise (scientists, science, and med professionals), and those who #worry about COVID-19 are most likely to say ‘yes’. i.e. strongest predictors in a model...

One key takeaway: the burden of trust fell more on sci/med rather than govt in the early stages of the pandemic (when data collected). This means doctors and scientists need to think hard about communicating in ways that exhibit trustworthiness. See:

Why are ♂️ more likely to say yes than ♀️? We don’t know for sure - but this is important and needs further investigation. Consistent with other COVID studies (@MonaSieverding):

seems to be true for other vaccines too. See:

General vaccine preferences also play a role - those who don't think vaccines, in general, are a good idea are less likely to accept a COVID-19 vaccine - but the specific effects noted above around this particular vaccine appear to be over and above that.

Some important caveats: Samples were matched to country on age and sex - but not 100% representative. Our questions focused on a hypothetical vaccine (data collected before vaccine announcements in Nov 2020).
