A COVID-19 booster dose increases protection against the coronavirus. But in an interview, comedian Bill Maher incorrectly said COVID-19 booster shots were “useless” and could cause “immune system fatigue.” Online, others have made similar claims. There is no basis for the notion that the immune system would tire out, even after repeated boosters.
Misconception: Value of Vaccination
Scientist Misleads on COVID-19 Vaccine Effectiveness and Vaccine Safety for Children
The approved and authorized COVID-19 vaccines in the U.S. are effective at preventing severe disease, and experts say the benefits of vaccination for children outweigh any known or potential risk. But social media users have shared video of Dr. Robert Malone misleadingly asserting that the COVID-19 vaccines are “not working” and claiming without evidence that many children “will be hospitalized” and may experience brain damage and infertility due to the vaccines.
Article Makes Unfounded Claims Linking Athletes’ Injuries, Deaths to Vaccines
Many U.S. athletes have been vaccinated against COVID-19 without any adverse effects. But a conservative outlet has cited a list of supposedly vaccine-injured athletes to claim “there may be something wrong with the vaccine.” There’s no proof that the listed athletes — most of them are actually retired — were harmed by the vaccines.
Benefits Outweigh Risks of Pediatric COVID-19 Vaccine, Contrary to Posts Misusing VAERS Data
Facebook Post Spreads Bogus Claim About ‘Detox’ After Vaccination
A vaccination can’t be reversed through any “detox” process, medical experts say. Yet, a social media post is spreading the false claim that a bath with borax can “get rid” of a COVID-19 vaccine. The bath may remove some water from the body, but not the molecules associated with vaccines, a toxicologist told us.
Aaron Rodgers’ Inaccurate COVID-19 Claims
Japan Continues to Use Vaccines, Not Ivermectin, to Fight COVID-19
More than 70% of Japan’s population has received the COVID-19 vaccines, and the government is moving ahead with a booster shot in December. But a conservative radio host in the U.S. falsely claimed, “Japan drops vax rollout, goes to Ivermectin.” Japan hasn’t stopped its vaccine program and hasn’t approved ivermectin as a COVID-19 treatment.
Why It’s Easy to Misinterpret Numbers of Deaths Among the Vaccinated
Raw numbers of hospitalizations or deaths among those who are vaccinated are not a good indicator of whether vaccines are effective. If the large majority of a population is vaccinated, it’s not surprising if most deaths are among the vaccinated. But social media posts misuse data from the U.K. to suggest the COVID-19 vaccines don’t work.
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.
COVID-19: The Unvaccinated Pose a Risk to the Vaccinated
Q: How do people who have not been vaccinated against COVID-19 pose a risk to people who have been vaccinated?
A: An unvaccinated person who is infected with COVID-19 poses a much greater risk to others who are also unvaccinated. But vaccines are not 100% effective, so there is a chance that an unvaccinated person could infect a vaccinated person — particularly the vulnerable, such as elderly and immunocompromised individuals.
