Studies have found that COVID-19 increases the risk for heart complications, and that the benefits of COVID-19 vaccination outweigh the risks for males and females in all age groups. Social media posts, however, have misinterpreted and publicized a criticized study that claims to have identified a correlation between emergency calls for cardiac events and the vaccination rate in Israel.
Q. Are vaccinated and boosted people more susceptible to infection or disease with the omicron variant than unvaccinated people?
A. No. Getting vaccinated increases your protection against COVID-19. Sometimes, certain raw data can suggest otherwise, but that information cannot be used to determine how well a vaccine works.
The World Health Organization can make recommendations after the declaration of a global emergency, but it has no control over any nation’s decisions. Yet conservatives in the U.S. falsely claim that amendments proposed by the Biden administration to existing global health regulations, and a new WHO pandemic treaty, will threaten U.S. sovereignty.
The U.S. indirectly funded some bat coronavirus research at a lab in Wuhan, China. But those experiments could not have led to the coronavirus that causes COVID-19, because the viruses used were very different. Yet former White House trade adviser Peter Navarro repeated a false claim that Dr. Anthony Fauci “killed a lot of people” by funding the lab.
The Pfizer/BioNTech COVID-19 vaccine showed a final efficacy of 91% against symptomatic illness in its phase 3 trial. Social media posts wrongly claim recently released Pfizer documents show the vaccine is “12% effective.” That appears to be a misreading of data released more than a year ago.
Once scarce, Paxlovid, an antiviral pill that is the preferred treatment for non-hospitalized high-risk COVID-19 patients, is no longer in such short supply. Here, we explain what the drug does, how well it works and what questions remain.
When Joe Biden was sworn in as president, two COVID-19 vaccines had already been authorized and millions of people nationwide had been vaccinated against the disease. But in a May 12 tweet touting economic progress made under Biden, the White House falsely claimed that “there was no vaccine available” at the time he was inaugurated.
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.
What does a fact-checking organization do when the facts aren’t clear? And what happens when reputable scientists disagree about a public health policy?
