Studies show the COVID-19 vaccines boost the antibody levels and improve the immune response of those who previously had COVID-19. The vaccines do not “wipe out” the antibodies developed by a person who had recovered from the disease, as social media posts have falsely claimed for months.
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.
Although scientists are still debating what the community, or herd, immunity threshold is for COVID-19, most epidemiologists estimate that between 40% to 70% of a population would need to be vaccinated or have prior exposure to the virus for an outbreak to begin to die out.
