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.
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.
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.
People who receive some vaccines that use live weakened viruses to stimulate a strong and lasting immune response sometimes release small amounts of those viruses outside of their bodies. That’s expected, and it doesn’t mean that they put vulnerable populations in “harm’s way,” as a post misleadingly suggests.

The cause of the uptick is unknown, but there’s no evidence that it’s due to COVID-19 vaccination, as some social media posts baselessly suggest.
Experts agree mammograms are the best tool to screen for breast cancer and that the benefits of the exam outweigh the risks. But a video in Spanish recommended that women over 40 skip mammograms, claiming the test is “unsafe” and “unnecessary.”
An injection of vitamin K for babies has been recommended and used safely for more than 60 years. It prevents life-threatening bleeding in newborns. But a viral post incorrectly claims the shot is harmful and unnecessary.
Influenza vaccines contain small amounts of various ingredients that allow them to work and keep them safe and long-lasting. A misleading meme suggestively lists more than two dozen substances it claims are in flu vaccines. But most are not present — and the ones that are aren’t dangerous.
Hearst Television, one of our media partners, produced this segment of “Get the Facts” partly based on our Q&A article on the updated COVID-19 vaccines.
