But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.
Scientists say the experiments Pfizer has performed on the coronavirus are standard for the industry. Baseless claims that the company is mutating the virus for profit, however, have been circulating since the release of a popular undercover video from the conservative activist group Project Veritas.
The derailment of a freight train carrying toxic chemicals in eastern Ohio has sparked a slew of unfounded claims by conservative commentators.

Polio, a paralytic disease caused by a virus, has been eliminated in the U.S. — and nearly wiped out globally — thanks to vaccines. But social media posts are reviving old, false claims that polio is instead caused by pesticides and outbreaks of the disease ended when people stopped using DDT.
An unclear tweet from New York City health officials was meant to caution residents that the latest omicron subvariant, XBB.1.5, might be more likely than previous variants to infect vaccinated or previously infected people.

Since his diagnosis in 1991, NBA player Magic Johnson has repeatedly said he contracted HIV through sexual transmission. But a viral social media post by a spreader of vaccine misinformation falsely claims that Johnson was exposed to the virus from a hepatitis B vaccine.
The COVID-19 vaccines were tested in large, randomized controlled trials before the Food and Drug Administration authorized them for emergency use. But a popular YouTube video spins a conspiracy theory that distorts legal codes to falsely claim otherwise.
Buffalo Bills player Damar Hamlin collapsed on the field and suffered a cardiac arrest moments after taking a hit to his chest during a tackle. While it’s not yet known why his heart stopped, some experts say his condition is most likely due to a heart rhythm problem as a result of that impact. Still, people on social media have baselessly speculated that it was caused by a COVID-19 vaccine.
While announcing a request for a grand jury probe into “crimes and wrongdoing” related to the COVID-19 vaccines, Florida Gov. Ron DeSantis and his panel of contrarian experts repeatedly suggested the shots were too risky. But such claims are unsupported and based on flawed analyses.
