How people judge anti-vaxxers who die from COVID-19
When people who publicly reject COVID-19 vaccines later die from the disease, observers have complex reactions to their fates, a new study suggests. While very few rejoice in the deaths of anti-vaxxers, some people believe those who are dogmatic against vaccines are deserving of worse outcomes – and that reaction is related to the political party affiliation and vaccination status of the person evaluating the anti-vaxxer.
