Colin Powell’s COVID-19 Death Followed Cancer Diagnosis, Treatment

Colin Powell’s COVID-19 Death Followed Cancer Diagnosis, Treatment

Former Secretary of State Colin Powell died from complications of COVID-19. Although he was fully vaccinated, he was also 84 years old and was a cancer patient who had undergone treatment for multiple myeloma — factors that put him at higher risk of a serious breakthrough illness. His death does not mean the COVID-19 vaccines don’t work, as many social media posts suggest.

Already Had COVID-19? Vaccines Boost Immunity, Not ‘Wipe Out’ Antibodies

Already Had COVID-19? Vaccines Boost Immunity, Not ‘Wipe Out’ Antibodies

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.

Basketball Star Bradley Beal’s Misleading Comments About COVID-19

Basketball Star Bradley Beal’s Misleading Comments About COVID-19

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.

Biden’s Controversial COVID-19 Vaccine Booster Plan

Biden’s Controversial COVID-19 Vaccine Booster Plan

The Biden administration announced that third shots of the two mRNA COVID-19 vaccines would be available to healthy people starting in mid-September. But many scientists say it’s not yet clear that boosters are needed.

Instagram Post Missing Context About Israeli Study on COVID-19 Natural Immunity

Instagram Post Missing Context About Israeli Study on COVID-19 Natural Immunity

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.

Indiana Doctor Piles On Bogus COVID-19 Claims in Viral Video

Indiana Doctor Piles On Bogus COVID-19 Claims in Viral Video

In a viral video, an Indiana physician baselessly claimed that the COVID-19 vaccines, which have been shown to be safe and effective, “fight the virus wrong and let the virus become worse than it would with native infection.” He also incorrectly said no vaccine prevents infection and contended that people previously infected with COVID-19 do not benefit from vaccination, despite studies that suggest otherwise.

Posts Misinterpret CDC’s Provincetown COVID-19 Outbreak Report

Posts Misinterpret CDC’s Provincetown COVID-19 Outbreak Report

Social media posts are misinterpreting the results of a Centers for Disease Control and Prevention report, which found 74% of people in a COVID-19 outbreak were vaccinated, to argue against immunization. But experts say the statistic is misleading without more context — and doesn’t mean that the vaccines don’t work.

Vaccines Remain Largely Effective Against Delta Variant, Counter to Claims From Fox News Guest

Vaccines Remain Largely Effective Against Delta Variant, Counter to Claims From Fox News Guest

Multiple studies show the FDA-authorized COVID-19 vaccines continue to be effective against the delta variant of the coronavirus, even if the potency of the vaccines is somewhat reduced. But a guest on Fox News falsely claimed the delta variant “really is not responsive at all, or protected at all by the vaccines” and there is “no clinical reason to go get vaccinated.”

Video Twists Advice on Delta Variant and Vaccination

Video Twists Advice on Delta Variant and Vaccination

An epidemiologist recommended that people get the COVID-19 vaccine because some evidence suggests an unvaccinated person who gets the delta variant is “twice as likely to require hospital treatment” than someone infected with the alpha variant. But a Facebook video twists that advice to claim that he said vaccinated people would be twice as likely to be hospitalized.
