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.
The Centers for Disease Control and Prevention recommends the use of ivermectin as a treatment for arriving refugees to treat parasitic infections. But a social media post by Dr. Simone Gold, a proponent of ivermectin as a treatment for COVID-19, references the CDC guidance without accurately explaining the reason why refugees are given the drug. The CDC has warned against using ivermectin to prevent or treat COVID-19.
Studies on whether ivermectin is beneficial in treating COVID-19 patients haven’t been conclusive, and health officials have warned people not to self-medicate. But multiple large trials are continuing to assess the antiparasitic drug. Yet, Sen. Rand Paul reportedly said researchers were “unwilling to objectively study” it because of “hatred” for Donald Trump. He later acknowledged studies are being done. Here we review the research.
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.
There was nothing unusual about the end of a routine press “pool spray” before a private meeting between fire officials and President Joe Biden in Idaho. But conservatives have falsely claimed the video shows someone cut off Biden’s microphone, for fear he was veering off-script.
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 Centers for Disease Control and Prevention has been tracking outbreaks of acute flaccid myelitis — a serious condition mainly affecting children — since 2014. The CDC hasn’t seen a reason for concern this year, but Facebook posts have wrongly claimed that the agency has issued a “warning of polio-like outbreak” this fall. The claim seems to have originated from an outdated news article.
A spokesperson for Senate Majority Leader Chuck Schumer has conceded that the New York Democrat falsely claimed that “all” Americans who wanted to leave Afghanistan “have come out.” Government officials say that fewer than 100 U.S. citizens, and an unknown number of U.S. legal permanent residents, who want to leave Afghanistan are still in the country.
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.
