Bell’s Palsy is not that rare, which is likely why cases were reported in the COVID-19 clinical trials and continue to be reported after the vaccines received EUA.
“People who have previously had Bell’s palsy may receive a COVID-19 vaccine. Cases of Bell’s palsy were reported following vaccination in participants in the COVID-19 vaccine clinical trials. However, the Food and Drug Administration (FDA) does not consider these to be more than the rate expected in the general population. They have not concluded these cases were caused by vaccination.”

Bell’s Palsy is not actually caused by any of these COVID-19 vaccines though.
COVID-19 Vaccines Are Not Associated With Bell’s Palsy
Associations between COVID-19 vaccines and Bell’s palsy have now been studied extensively.
“When compared with other viral vaccines, mRNA COVID-19 vaccines did not display a signal of facial paralysis.”

And except for a few case reports, there is no evidence that we are seeing more cases of Bell’s Palsy in those who have been vaccinated, or that getting vaccinated is causing anyone to develop Bell’s Palsy.

So why are we reading about folks developing Bell’s palsy after getting their COVID-19 vaccine?
Again, it is mostly because Bell’s palsy is relatively common and a lot of people are getting vaccinated and protected against COVID-19!
“Bell’s palsy is a fairly prevalent disorder that affects males and females in equal numbers. It is estimated that between 25 and 35 in 100,000 people in the United States are affected with Bell’s palsy. Approximately 40,000 individuals are diagnosed with Bell’s palsy in the United States each year.”
Bell’s Palsy
With 3 to 4 million getting vaccinated and protected each day, a lot of those people will naturally develop Bell’s palsy just because they were going to develop Bell’s palsy. It is just a coincidence that they also happened to recently get their COVID-19 vaccine.
