What could happen if I already had the chickenpox but forgot, and then got a chickenpox vaccine anyway?

In brief: Nothing.

The antibodies in your blood would neutralize the virus in the vaccine, with maybe a small (beneficial) bump up in the antibody levels.

In brief: Low risk of problems

For most people the immunity from having had a chicken pox infection remains in the background and gets recruited when the virus shows up again.
For adults, in the vast majority of cases receiving the vaccine will serve as a booster and improve your level of protection against chicken pox or shingles. The risk of side effects is small. The most common side effect is irritation the injection site.
