Side Effects to Report
side effects, while occurring infrequently, are potentially serious and should be reported immediately to a healthcare provider. These reactions can occur with any vaccine, and include, but are not limited to:
- A high fever
- Any unusual behavior changes (aside from the usual fussiness that typically occurs after vaccinations)
- A seizure
- Persistent, inconsolable crying lasting for three hours or more
- Signs of an allergic reaction, such as:
- An unexplained rash
- Swelling of the mouth or throat
- Difficulty breathing.
Your child may experience some or none of the side effects listed in this article. Unfortunately, there is no way for your child's healthcare provider to know beforehand if your child will have problems with a particular vaccine.
Therefore, make sure to let your child's healthcare provider know if your child develops any possible ActHIB side effects. Also, let your child's healthcare provider know if something "just does not seem right." While it may not be related to the vaccination, your child's healthcare provider will be able to diagnose and treat the problem, or provide reassurance if nothing is the matter.
