An Introduction to Havrix Side Effects
As with all vaccines, side effects are possible with
Havrix® (
hepatitis A vaccine). However, not everyone who receives the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Havrix. Your healthcare provider can discuss a more complete list with you.)
