Q: How do people who have not been vaccinated against COVID-19 pose a risk to people who have been vaccinated?
A: An unvaccinated person who is infected with COVID-19 poses a much greater risk to others who are also unvaccinated. But vaccines are not 100% effective, so there is a chance that an unvaccinated person could infect a vaccinated person — particularly the vulnerable, such as elderly and immunocompromised individuals.
Public health officials around the world have explained that erectile dysfunction is not a side effect of COVID-19 vaccines, but a viral tweet from rapper Nicki Minaj has spread the unfounded claim that it is. There is no evidence to support that claim.
Here we answer some questions about President Joe Biden’s plan to impose an emergency rule for businesses with 100 or more employees that would require workers to be fully vaccinated or be tested at least once a week.
Afghanistan has implemented a COVID-19 vaccination program and, although administration of vaccines has slowed due to internal armed conflicts, the program is still underway. But some prominent conservative purveyors of misinformation in the U.S. have made false claims about vaccination efforts and the impact of the pandemic in Afghanistan.
The Biden administration announced that third shots of the two mRNA COVID-19 vaccines would be available to healthy people starting in mid-September. But many scientists say it’s not yet clear that boosters are needed.
An Instagram post highlighted a headline about a non-peer-reviewed study from Israel that found that unvaccinated people previously infected with SARS-CoV-2 had greater immunity against the delta variant than never-infected people fully vaccinated with Pfizer/BioNTech’s COVID-19 vaccine. But the social media post omitted the study’s other finding that one dose of the vaccine enhanced protection for infection survivors.
The Pfizer/BioNTech COVID-19 vaccine was fully approved by the Food and Drug Administration, though an emergency use authorization also remains in place. Dr. Robert Malone misleadingly said Americans are being offered the shot only under the latter and that it carried different liability ramifications. The liability protections, afforded under a public health law, are the same for the two.
In this video, FactCheck.org and Univision Noticias teamed up to debunk false claims made by a doctor in Idaho about COVID-19 mRNA vaccines and treatments. It is available in both English and Spanish.
A digital device company is developing gel sensors that would monitor the wearer’s health and could potentially help to detect future outbreaks of disease. But conspiracy theorists are falsely claiming that the sensors are actually COVID-19-detecting microchips that will be used to track people’s movements.
The delta variant of the coronavirus that causes COVID-19 is more transmissible than previous forms of the virus, and has helped spur an increase in cases, including in children. But a chiropractor in a Facebook video wrongly claims that “it is not showing more of a problem.” That’s one of several misleading and false claims he makes about COVID-19.
