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.
Expanded reporting requirements and intense scrutiny of the hundreds of millions administered COVID-19 vaccine doses have driven record reporting of potential side effects to one of the government’s vaccine safety monitoring systems. Social media posts, however, have misleadingly insinuated that the increase in reports means the vaccines are unsafe.
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.
After getting the COVID-19 booster on Oct. 27, California Gov. Gavin Newsom canceled a trip and did not participate in any official public events for 12 days. Social media posts claimed, without evidence, that Newsom was suffering serious side effects from the booster. But his staff denied that he had an “adverse reaction” to the shot and, during this time, he appeared twice on social media and reportedly attended a wedding.
There is no evidence to indicate that the spike proteins generated by human cells following vaccination are a toxin or that they circulate in the body and damage tissues, contrary to what a Canadian virus immunologist recently claimed.
There is no evidence that vaccines could cause harm to people who already have been infected with SARS-CoV-2 or have become ill with the disease COVID-19. On the contrary, recent studies show the vaccine gives an important immunity boost to those previously infected and suggest that one dose might be enough.
Viral social media posts cite a flawed paper in falsely claiming the Centers for Disease Control and Prevention changed death certificate procedures and violated federal law, resulting in wildly inflated COVID-19 deaths. The CDC hasn’t altered how death certificates for COVID-19 are filled out, and there is no federal law governing the process.
A video stoking fears of the COVID-19 vaccines in the Black community is being promoted online. But the film repeats misrepresentations about vaccines, generally, and exploits historical cases of unethical medical conduct to suggest without evidence that COVID-19 vaccines are unsafe.
Q: Do the COVID-19 vaccines cause infertility?
A: There’s no evidence that approved vaccines cause fertility loss. Although clinical trials did not study the issue, loss of fertility has not been reported among thousands of trial participants nor confirmed as an adverse event among millions who have been vaccinated.
Baseball legend Henry “Hank” Aaron died from natural causes, according to the medical examiner’s office in Fulton County, Georgia. There’s no evidence that his death was a result of being vaccinated against COVID-19 in early January, as multiple posts on social media suggested.
