People vaccinated with an authorized or approved COVID-19 vaccine can donate blood immediately after receiving a shot if they’re feeling well. Social media posts distort a question from the American Red Cross to baselessly claim the vaccines are unsafe.
SciCheck
FactCheck.org’s SciCheck feature focuses exclusively on false and misleading scientific claims that are made by partisans to influence public policy. It was launched in January 2015 with a grant from the Stanton Foundation. The foundation was founded by the late Frank Stanton, president of CBS for 25 years, from 1946 to 1971.
Study Largely Confirms Known, Rare COVID-19 Vaccine Side Effects
An international study of around 99 million people confirmed known serious side effects of COVID-19 vaccination. It also identified a possible relationship between the first dose of the Moderna vaccine and a small risk of a neurological condition. Social media posts about the study left out information on the vaccines’ benefits and the rarity of the side effects.
Posts Mislead About COVID-19 Vaccine Safety With Out-of-Context Clip of FDA Official
Given the extra scrutiny and large number of doses, reports of possible side effects to a vaccine safety monitoring system increased with the COVID-19 vaccines. The high number of reports does not mean the vaccines are unsafe, contrary to suggestions made by posts sharing a clip of a Food and Drug Administration official acknowledging the surge.
CDC, Experts Say Fluoridated Water Is Safe, Contrary to RFK Jr.’s Warnings
The Centers for Disease Control and Prevention and multiple expert groups endorse water fluoridation as a safe way to reduce tooth decay. However, independent presidential candidate Robert F. Kennedy Jr. made a sweeping claim about fluoride’s effects on the nervous system, and promised to order the CDC to ban fluoride from tap water.

Review Article By Misinformation Spreaders Misleads About mRNA COVID-19 Vaccines
The mRNA COVID-19 vaccines have a good safety record and have saved millions of lives. But viral posts claim the contrary, citing a recent peer-reviewed article authored by known COVID-19 misinformation spreaders and published in a controversial journal. The paper repeats previously debunked claims.
Electric Vehicles Contribute Fewer Emissions Than Gasoline-Powered Cars Over Their Lifetimes
Q: Are electric cars really better for the environment than gasoline-powered cars over their lifetimes?
A: Yes. Electric vehicles typically release fewer greenhouse gas emissions than internal combustion engine vehicles during their life cycles, even after accounting for the increased energy required to make their batteries. And their carbon footprints are expected to get smaller in the near future.
Posts Misrepresent Mouse Study of Pangolin Virus
A study showed a type of lab mouse is highly susceptible to a coronavirus derived from pangolins, a scaly, cat-sized mammal. This doesn’t mean the virus is dangerous to humans. The virus is related to the one that causes COVID-19 but did not descend from it, contrary to claims that it is a “mutant COVID-19 strain.” Nor did scientists “craft” the virus.
Posts Mislead About Measles, MMR Vaccine Amid Recent Outbreaks
Measles is a highly contagious disease that can be serious and even fatal. Fortunately, it can safely be prevented by vaccination. But in the wake of outbreaks in the U.S. and elsewhere — likely in large part due to low vaccination coverage — social media posts have downplayed the risks of measles and falsely claimed the vaccine “is more dangerous than the actual illness.”
Posts Misrepresent WHO Term ‘Disease X’ for Possible Future Illness
The World Health Organization began using the term “Disease X” in a 2018 planning document to refer to a “currently unknown” illness. But since the term was used at the January meeting of the World Economic Forum, conspiracy theorists baselessly claim Disease X is part of a “Globalist Plan to … Install World Government.”
