A preprint on a Yale-based study described chronic symptoms self-reported after COVID-19 vaccination by 241 members of an online group. The paper, which has not been peer-reviewed, did not show how common these symptoms are in the general population, nor whether vaccinations caused them — limitations popular online posts did not make clear.
Data from around the world support the general safety of the COVID-19 vaccines. Some people online, however, incorrectly claim that illegally obtained data from New Zealand show the vaccines have killed 13 million people worldwide. Experts say the analysis is bogus.
People who receive some vaccines that use live weakened viruses to stimulate a strong and lasting immune response sometimes release small amounts of those viruses outside of their bodies. That’s expected, and it doesn’t mean that they put vulnerable populations in “harm’s way,” as a post misleadingly suggests.
The mRNA COVID-19 vaccines — like many other vaccines — can contain small amounts of DNA left over from the manufacturing process. There’s no evidence this residual DNA causes “turbo cancer,” or very aggressive cancer. Nor did Moderna admit that “mRNA Jabs Cause Turbo-Cancer,” contrary to an online article that misconstrues a line from a patent application.
A recent federal report shows a 3% increase in the U.S. infant mortality rate between 2021 and 2022, which is the first statistically significant rise in 20 years. The cause of the uptick is unknown, but there’s no evidence that it’s due to COVID-19 vaccination, as some social media posts baselessly suggest.
Being vaccinated against COVID-19 helps protect pregnant people from severe COVID-19. When given during pregnancy, the vaccines can also reduce the risk of hospitalization from COVID-19 early in a baby’s life. A new study adds to the evidence that vaccination during pregnancy is safe for babies, contrary to social media and online claims.
In a “PBS NewsHour” interview, independent presidential candidate Robert F. Kennedy Jr. repeatedly denied previously saying that “no vaccine” is safe and effective. But Kennedy said exactly that on the Lex Fridman podcast in July.
COVID-19 vaccination reduces the risk of death from COVID-19. Social media posts have misused survey data and adverse events reports to falsely claim that COVID-19 vaccines have killed more people than COVID-19. But serious adverse events resulting from vaccination, including deaths, are rare.
Serious side effects after COVID-19 vaccination are rare, and there isn’t evidence people need to undergo a “spike protein detoxification” regimen after getting vaccinated, contrary to claims made online. Nor has such a regimen been shown to help people recover from long COVID, or long-term health problems after having COVID-19.
Flu shots and vaccines that protect children against measles, mumps and rubella have been effective in preventing illness, serious disease and death. But a meme has been circulating with the false suggestion that those vaccines are ineffective. Actually, they’ve saved millions of lives and have eliminated both measles and rubella in the U.S.
