Pfizer Safety

Does European Medicines Agency data show more than 1.1 million adverse drug reactions and more than 30,000 deaths by COVID-19 vaccinations? Yes, that's true: Those numbers are found in EudraVigilance, the European Union's database of suspected adverse drug reaction reports. But the numbers don't tell the full story as the meaning of EudraVigilance reports is unclear because the numbers are…

Will the Pfizer COVID-19 vaccine kill 117 children ages 5 to 11 to save one child from dying of the virus? No, that's not true: There is no evidence to support that claim, which was made using data reported to the Vaccine Adverse Event Reporting System (VAERS), an unverified alert system. The accuracy and significance of VAERS reports is unclear…

Is myocarditis, a rare disease that causes the swelling of the heart muscle, "irreversible"? Not exactly: Many patients fully recover from myocarditis, although the damage done by the disease varies based on its severity. The claim appeared in a Facebook post (archived here) on November 11, 2021. The post has what appears to be a screenshot of text that reads:…

Did Dr. Anthony Fauci admit that COVID vaccines did not work as advertised and that the vaccinated are in great danger? No, that's not true. The director of the U.S. National Institute of Allergy and Infectious Diseases and the Biden administration's chief medical adviser strongly and consistently endorses the vaccination effort and has never suggested the vaccinated are at risk.…

Are children 50 times more likely to be killed by the COVID-19 vaccines than by the virus itself? No, that's not true: The person who made the claim offered no proof for the claimed numbers of deaths from the COVID vaccine.

Does Pfizer "admit" that people given its COVID-19 vaccine "shed" spike proteins and infect unvaccinated people? No, that's not true. The claim is based on the standard clinical study protocol used for a wide range of medicines. There is no publicly available evidence the mRNA COVID-19 vaccines cause vaccinated persons to cast off excess spike proteins. The mRNA vaccines teach…

Does Pfizer's COVID-19 vaccine attack human blood and cause dangerous clots? No, there's no publicly available evidence to support the claim. There is no website at the address the video maker sends viewers to for details on the blood exam. The Food & Drug Administration in 2009 barred this video's maker, Dr. Richard Fleming, from working with anyone seeking FDA…

Did Pfizer include tromethamine, an "ingredient used to stabilize heart attack victims" in its COVID-19 vaccine for children aged 5-11 years old? Only as a stabilizing pH buffer to make it easier to store. While tromethamine is being used as an inactive ingredient in the Pfizer-BioNTech COVID-19 vaccine authorized for use in children aged 5-11 years old, both Pfizer and…

Are vaccinated pilots dropping dead midflight? No, that's not true: "There is no truth to the claims about these two pilots," American Airlines told Lead Stories.

A message on the site notes that it "contains humor,…
