Those who are not vaccinated against COVID-19 are more prone to serious illness and are dying at higher rates than those who are vaccinated. But partisan social media accounts, including a post by a member of former President Donald Trump’s campaign legal team, continue to misleadingly suggest the vaccines are unnecessary and discourage their use.
NBA star Bradley Beal made some misleading comments — shared in viral video clips — about the effectiveness of COVID-19 vaccines. No vaccine is 100% effective, but clinical trials and studies show the COVID-19 vaccines are very effective at preventing illness, particularly serious illness, including for those previously infected, such as Beal.
An Instagram post highlighted a headline about a non-peer-reviewed study from Israel that found that unvaccinated people previously infected with SARS-CoV-2 had greater immunity against the delta variant than never-infected people fully vaccinated with Pfizer/BioNTech’s COVID-19 vaccine. But the social media post omitted the study’s other finding that one dose of the vaccine enhanced protection for infection survivors.
Florida health officials have reported a 60% rise in COVID-19 cases, and hospitals are reporting that 95% of COVID-19 patients are not fully vaccinated. But a Facebook post makes the baseless claims that Florida’s numbers are not going up, and that all COVID-19 patients recently admitted to a Palm Beach County hospital had been vaccinated.
Community immunity, often referred to as herd immunity, refers to a situation in which enough of a population is immune to an infectious disease, either through vaccination or prior infection, to largely stop transmission of the disease and indirectly protect those who aren’t immune.
