Rotavirus Vaccine Safety

Key points

You can protect against rotavirus disease with vaccination.

Overview

Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines).

The rotavirus vaccine is effective at preventing rotavirus disease.

Available vaccines & manufacturer package inserts

  • The FDA approved Rotarix in 2008 for use in infants 6 to 24 weeks of age.
  • The FDA approved RotaTeq in 2006 for use in infants 6 to 32 weeks of age

Who should & should not get the vaccine

Most babies who get rotavirus vaccine do not have any problems with it.

Common side effects

  • Irritability.
  • Mild, temporary diarrhea or vomiting.

Some studies suggest that rotavirus vaccination possibly causes a small increase in the risk of intussusception, a type of bowel blockage. This side effect is very rare.

Vaccines, like any medicine, can have side effects. Most babies who get rotavirus vaccine do not have any problems with it.

Report possible adverse events to VAERS‎

The Vaccine Adverse Event Reporting System (VAERS) is an early warning system, co-managed by CDC and FDA, that monitors for potential vaccine safety problems. Healthcare providers and vaccine manufacturers are required by law to report certain adverse events (any side effect or health problem after vaccination that is concerning to you, even if you are not sure if the vaccine caused the event) following vaccination to VAERS; patients and caregivers can also submit reports.

A closer look at the safety data

Studies from the United States and other countries show a small increased risk of intussusception following rotavirus vaccination. About 1 in 20,000 US infants to 1 in 100,000 US infants who get rotavirus vaccine might develop intussusception within a week of getting the vaccine. This means that between 40 and 120 U.S. infants might develop intussusception related to rotavirus vaccine each year.

How CDC monitors vaccine safety

CDC and the Food and Drug Administration (FDA) are committed to ensuring that vaccines provided to the public are safe and effective. Once vaccines are licensed or authorized for emergency use in the United States, CDC and FDA continuously monitor them through several safety systems.
