As the virus that causes COVID-19 has evolved, the vaccines have become less effective in preventing symptomatic infection while remaining highly effective in preventing severe disease and death. This shift has been misrepresented by anti-vaccine influencers who falsely claim that it means the vaccines don’t work and have been ineffective all along.
Dr. Anthony Fauci has announced that in December he will step down from his positions as chief medical adviser to President Joe Biden and as head of the National Institute of Allergy and Infectious Diseases and its laboratory of immunoregulation. Here are some of the false and misleading claims about Fauci, his work and his public health guidance that we have written about since the coronavirus pandemic began in 2020.
Studies have repeatedly found that COVID-19 vaccination does not increase the risk of miscarriage. Bogus claims that 44% of pregnant women in the Pfizer/BioNTech COVID-19 vaccine trial miscarried rely on a faulty tally of miscarriages that counted each miscarriage twice and included miscarriages from people in the placebo group.
In a 2012 documentary, Magic Johnson discussed his HIV diagnosis and how it has affected his career. Social media posts are sharing an image from the documentary to falsely claim it shows Johnson donating blood for people with COVID-19. Johnson hasn’t donated HIV-infected blood for any medical reason.
After a long delay marred by manufacturing troubles, a COVID-19 vaccine from Novavax became the fourth such vaccine authorized in the U.S. We review how it works and how it’s different from its competitors.
It’s estimated that COVID-19 vaccines have saved millions of lives, but false claims continue to cast doubt on their safety and efficacy. One such claim that has spread around the world falsely suggests that three Canadian doctors died from the shots. But they each died of a long-term illness unrelated to the vaccines.
Viral claims have repeatedly misrepresented unverified data from a U.S. vaccine safety system that encourages reports of any potential side effects — whether they’re likely to be caused by the vaccine or not. Now we’re seeing the same phenomenon with a similar system in Germany. Some have wrongly claimed Germany found the COVID-19 vaccine caused “serious side effects” in a large number of people.
The mRNA COVID-19 vaccines teach the immune system to recognize and fight the coronavirus, greatly reducing the likelihood of severe disease if a person is infected. There is no evidence the vaccines impair immunity, as some, including Fox News’ Tucker Carlson, have baselessly claimed.
In young children, the Pfizer/BioNTech and Moderna COVID-19 vaccines are expected to primarily protect against severe disease. Both shots successfully met the set benchmarks for vaccine effectiveness, which involved comparing antibody responses to those of adults. Online posts critical of government recommendations for the pediatric vaccines, however, fail to mention these essential data.
Children under 5, including those as young as 6 months of age, are now able to be vaccinated against COVID-19. Here, we explain what’s known about the two coronavirus vaccines for the youngest children.
