Do vaccines cause mouth lesions?

The Claim:

A tweet claims that studies show COVID vaccinations cause oral lesions.

The Facts:

A comprehensive study spanning five databases looked for case reports, case series, and observational studies. Out of those, they found just 18 cases. That is a drop in the ocean when you consider that 200 million Americans have received a COVID vaccine.

COVID infection is a different story. Over a thousand instances of oral lesions are associated with COVID infection.

We don’t see smoke here, let alone any fire. There may be a very rare association between the COVID vaccine and some mouth lesions, whereas there is definitely a much less rare association between COVID infection and mouth lesions.
