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.
Clinical and real-world studies have shown that the COVID-19 vaccines are effective in preventing serious disease, and there is a long history of vaccine requirements in the U.S. But a list of bogus claims, shared around the world in recent months, falsely attributes unique characteristics and requirements to COVID-19 vaccines.
As of early December, unvaccinated adults were about 97 times more likely to die from COVID-19 than fully vaccinated people who had received boosters, according to Centers for Disease Control and Prevention data. But a Twitter user falsely implied that the death rate for the unvaccinated included people who had only one or two doses of a vaccine. The CDC said “unvaccinated” means someone has “not been verified to have received COVID-19 vaccine.”
The National Institutes of Health has not recommended and the Food and Drug Administration has not approved ivermectin as a COVID-19 treatment. But a Facebook post misleadingly implies that an article published on the NIH website is an endorsement of the drug to treat COVID-19. The NIH and FDA have said more clinical studies are needed.
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.
A Japanese company found that the antiparasitic drug ivermectin showed an “antiviral effect” against the omicron variant in a lab setting. Reuters has corrected a story in which it “misstated” that the drug was effective in a phase 3 clinical trial with human subjects. Some social media users have repeated Reuters’ reporting error but have not repeated the correction.
Neither primary vaccination nor natural immunity is generally stopping infections with the omicron variant, but research shows booster doses substantially increase protection. Yet, Republican Sen. Rand Paul claimed that a case of COVID-19 provides “an immunity better than the vaccine.”
Polymerase chain reaction, or PCR, tests for COVID-19 are highly accurate. People on social media, however, are circulating lists of germs that they baselessly claim will cause such tests to be falsely positive. In reality, it’s the opposite. The lists include pathogens that have been tested by the manufacturers and did not react to the test.
At a rally in Arizona on Jan. 15, former President Donald Trump waded into the debate over state policies allowing health systems to consider race as a risk factor when prioritizing the allocation of limited supplies of some COVID-19 therapeutics. According to Trump, it translates to white people being denied life-saving medicines and vaccines.
Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, discussed a recent study that found that on the rare occasion when fully vaccinated people died from COVID-19, they often had multiple risk factors for severe disease. But her reference to vaccinated people was cut in a version of the interview — and conservative figures misleadingly claimed she was talking about all COVID-19 deaths.
