Facebook, which routinely adds its editorial comments to posts with which it disagrees, recently "fact-checked" a woman's complaint about her reaction to a coronavirus vaccine.
Desiree Penrod, 25, said on Facebook after getting vaccinated in early March: "The vaccine is killing me today. My arm hurts, beyond exhausted, headache, stomach cramps and earaches."
Penrod also posted: "Multiple people told me that I looked pale today. Yesterday, I was fine but today it's taking its toll on me."
Facebook, citing the World Health Organization, added a disclaimer to a post by Penrose, "COVID-19 vaccines go through many tests for safety and effectiveness before they're approved."
A week later, Penrod died. Her obituary said she "passed away unexpectedly."
Facebook's editorial comment citing the WHO provided a link to the international organization, whose investigation into the origin of COVID-19 has been criticized because of China's control of it.
"Previous posts by Penrod appear to show she was experiencing seizures prior to vaccination and was likely not a good candidate to receive the vaccine due to her medical issues."
