Dozens of studies support the use of the mRNA COVID-19 vaccines, which have a good safety profile and work well in preventing severe disease and death. Yet, citing a single, flawed paper, a British cardiologist known for peddling misinformation has misleadingly argued that the shots are harmful and “should never have been approved.”
May 11 will mark the end of the federal public health emergency for COVID-19, bringing changes to health care and public benefits.
COVID-19 vaccines substantially reduce the risk of dying from COVID-19, and serious side effects are very rare. Excess deaths among working-age adults in 2021 and 2022 were due to COVID-19 and other factors, not vaccination. Faulty logic underlies claims that vaccines caused mass disability and economic harm.
Outside of long COVID or very severe cases, most research suggests COVID-19 doesn’t cause lasting damage to the immune system. A few studies have found evidence of some possible damage, but nothing as severe as an immunodeficiency. People on social media, however, are misinterpreting a recent study to incorrectly claim COVID-19 is HIV-like.
Vaccination and infection both provide protective immunity to COVID-19, particularly against severe disease. But gaining immunity through infection is far riskier than vaccination. Posts citing a new Lancet study omit that important context and also misleadingly claim the study shows immunity after infection is superior to vaccination immunity.
Scientists say the experiments Pfizer has performed on the coronavirus are standard for the industry. Baseless claims that the company is mutating the virus for profit, however, have been circulating since the release of a popular undercover video from the conservative activist group Project Veritas.
Health problems that are reported to the Vaccine Adverse Event Reporting System after vaccination are not necessarily caused by a vaccine. Yet social media posts distorted a comment from a Centers for Disease Control and Prevention official about such reports to falsely say he admitted the vaccines cause “debilitating illnesses.”
Thai officials attributed the collapse of the king’s eldest daughter in December to a bacterial infection, not to COVID-19 vaccination, as some have baselessly claimed online. Rumors about the country banning Pfizer’s vaccines are also “fake news,” officials said.
Research suggests COVID-19 vaccination can cause changes in a person’s menstrual cycle. But the changes are small and short-lived — and studies have shown there’s no effect on fertility. Yet people on social media are suggesting the cycle changes are evidence of harm.
An unclear tweet from New York City health officials was meant to caution residents that the latest omicron subvariant, XBB.1.5, might be more likely than previous variants to infect vaccinated or previously infected people. Social media posts misinterpreted the tweet to mean that vaccinated people were at higher risk than unvaccinated people.
