Russia developed a COVID-19 vaccine, Sputnik V, in 2020. President Vladimir Putin has said he received three doses of the vaccine, and the government continues to urge Russians to get vaccinated against the disease. But social media posts falsely claimed Putin “ordered the destruction of all” COVID-19 vaccine stockpiles in Russia.
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.”
Moderna’s CEO said in January that the company’s total production in 2019 was “100,000 dose,” referring to all its vaccines and therapeutics. Online posts distorted the remarks to falsely claim Moderna made COVID-19 vaccines “before the pandemic started.” Moderna’s first batch of COVID-19 vaccines wasn’t ready until February 2020.
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.
Government health agencies disclosed a potential safety concern for strokes in those 65 and older with one of the COVID-19 vaccines, but the agencies haven’t found any causal relationship and the concern was flagged by just one of several monitoring systems. Anti-vaccine campaigners, however, have wrongly claimed the agencies have found a link between the boosters and strokes.
Sports medicine experts say there has been no increase in sudden death or cardiac injury among U.S. athletes since the COVID-19 vaccines became available. Yet anti-vaccine campaigners, comparing unreliable numbers to an unrelated study, have again spread a false narrative about vaccine safety since NFL player Damar Hamlin suffered cardiac arrest.
Buffalo Bills player Damar Hamlin collapsed on the field and suffered a cardiac arrest moments after taking a hit to his chest during a tackle. While it’s not yet known why his heart stopped, some experts say his condition is most likely due to a heart rhythm problem as a result of that impact. Still, people on social media have baselessly speculated that it was caused by a COVID-19 vaccine.
A vaccine safety surveillance study from the Food and Drug Administration has been misrepresented online. The paper did not establish a link between the Pfizer/BioNTech COVID-19 vaccine and blood clots, as some have claimed — and to date, other, more robust research has not identified such associations.
