Facebook Video Misrepresents CDC Report on COVID-19 Vaccine Boosters

Facebook Video Misrepresents CDC Report on COVID-19 Vaccine Boosters

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.

Posts Misinterpret Pfizer COVID-19 Vaccine Safety Monitoring Document

Posts Misinterpret Pfizer COVID-19 Vaccine Safety Monitoring Document

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.

Polio Vaccine Is a Four-Shot Series, Contrary to Greene Comments

Polio Vaccine Is a Four-Shot Series, Contrary to Greene Comments

The Centers for Disease Control and Prevention says it “recommends that children get four doses of polio vaccine.” But Rep. Marjorie Taylor Greene, when speaking against a potential fourth dose of the COVID-19 vaccines, wrongly suggested that the CDC doesn’t recommend four shots of the polio vaccine.

Post Misconstrues Public Health Awareness Campaigns About Blood Clots

Post Misconstrues Public Health Awareness Campaigns About Blood Clots

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. 

COVID-19 Vaccines Have Prevented Deaths, Contrary to Misleading Graphic on Social Media

COVID-19 Vaccines Have Prevented Deaths, Contrary to Misleading Graphic on Social Media

Studies have shown that COVID-19 vaccines have prevented severe disease and deaths. But bogus claims that they don’t work continue to circulate online. One claim relies on a misleading graph showing cumulative deaths in the U.S., but omits information about the number of deaths among the vaccinated versus unvaccinated since the shots became available.

Benefits of COVID-19 Vaccination Outweigh the Rare Risk of Myocarditis, Even in Young Males

Benefits of COVID-19 Vaccination Outweigh the Rare Risk of Myocarditis, Even in Young Males

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.

U.S. COVID-19 Vaccines Follow Conventional Health Standards and Protocols

U.S. COVID-19 Vaccines Follow Conventional Health Standards and Protocols

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.

Latest CDC Data: Unvaccinated Adults 97 Times More Likely to Die from COVID-19 Than Boosted Adults

Latest CDC Data: Unvaccinated Adults 97 Times More Likely to Die from COVID-19 Than Boosted Adults

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.”

COVID-19 Booster Enhances Protection, Contrary to ‘Immune Fatigue’ Claims

COVID-19 Booster Enhances Protection, Contrary to ‘Immune Fatigue’ Claims

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.

Scientist Misleads on COVID-19 Vaccine Effectiveness and Vaccine Safety for Children

Scientist Misleads on COVID-19 Vaccine Effectiveness and Vaccine Safety for Children

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.
