Can rotavirus infection be prevented with a vaccine? Are any side effects associated with the rotavirus vaccine?

Because the virus is so prevalent, it is very difficult or even impossible to prevent rotavirus infection in unvaccinated people. Even places with excellent standards of hygiene and sanitation can become contaminated. Vaccination is the most effective preventive measure and is very effective in preventing severe rotavirus disease in young children and infants.

There are two rotavirus vaccines are licensed for vaccinating infants in the United States, known as RotaTeq and Rotarix. Both are given orally and do not require an injection. The rotavirus vaccines are most effective if the first dose is given before age 15 weeks, and all doses should be complete by 8 months of age.

  • RotaTeq (RV5) is given on a schedule of three doses at ages 2 months, 4 months, and 6 months.
  • Rotarix (RV1) is given on a schedule of two doses at ages 2 months and 4 months.

Side effects of the vaccine are very uncommon. As with all vaccines, rare allergic reactions may occur. Other uncommon side effects are temporary and can include irritability, vomiting, and diarrhea.
