The Claim:
In a video online, Naomi Wolf claims that COVID vaccines damaged the part of the brain called the prefrontal cortex. She says this caused changes in people’s personalities and made it harder for them to think clearly.
The Facts:
Naomi Wolf has a PhD in English literature, not medicine. She does not provide studies or other evidence to support this claim. She also does not give clear examples of people losing the ability to think or having major personality changes because of a COVID vaccine.
Billions of COVID vaccine doses have been given around the world. If the vaccines commonly caused serious changes in thinking or personality, doctors, brain specialists, mental health experts, and vaccine safety systems would likely have found a clear pattern.
Brain scans have not found physical changes in the brain after mRNA COVID vaccination. In contrast, studies have found that COVID infection itself can harm the brain. Some people have had problems with memory and thinking after an infection, and some studies have found drops in IQ scores.
