A string of unexplained hepatitis cases in children has been reported in the U.S. and in other countries. The cause is not yet known, but the top suspect so far is a strain of adenovirus. Contrary to some social media posts, there is no evidence that COVID-19 vaccination is involved. Most of the children are too young to even qualify for the vaccine.
The American Red Cross and other blood collectors in the U.S. strongly encourage everyone who is feeling healthy to donate blood, including people who have received a COVID-19 vaccine. But a social media post falsely implies the organization does not use the blood from vaccinated people.
A report from the Centers for Disease Control and Prevention found that side effects such as a sore arm or headache following a booster dose of the mRNA COVID-19 vaccines were less frequent than after the second dose. But a Facebook video from a chiropractor misrepresents the report’s findings, the systems that record adverse events and the availability of information on those events.
A Pfizer document recently released by the Food and Drug Administration describes adverse events reported following vaccination and attests to the continued safety of the company’s COVID-19 vaccine. A popular video and other online posts, however, incorrectly imply that the vaccine caused the events.
The Centers for Disease Control and Prevention and Pfizer tweeted in February about the dangers of blood clots in veins, which are relatively common and affect as many as 900,000 Americans each year. A story shared on social media, however, misleadingly linked those public health reminders to the COVID-19 vaccines.
Rare cases of myocarditis have been reported following the mRNA COVID-19 vaccines, particularly among young males after a second dose. Most cases resolve quickly without the need for advanced therapies, although research on any potential long-term effects is ongoing. Nonetheless, the benefits of vaccination outweigh the risks in all populations, even in young males.
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.
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.
TV actress Betty White passed away at age 99 on Dec. 31. Following her passing, various falsehoods appeared on social media about White, including claims that she died after getting a COVID-19 booster shot and that she was the sister of former first lady Barbara Bush. White died of natural causes, according to her agent, and she had no siblings.
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.
