Side Effects to Report
There are a number of rare but serious side effects with Comvax
or other childhood vaccines that you should report to your child's healthcare provider. These 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
- Weakness, tingling, or paralysis (which may be signs of Guillain-Barré syndrome)
- 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 the vaccine.
Therefore, make sure to let your child's healthcare provider know if your child develops any adverse reactions. Also, let your child's healthcare provider know if something "just does not seem right." While it may not be a side effect of Comvax, your child's healthcare provider will be able to diagnose and treat the problem, or provide reassurance if nothing is the matter.
