) is a childhood vaccine approved to prevent rotavirus
. It is given by mouth as a series of three separate doses. Rotavirus causes severe diarrhea
in infants and young children, sometimes resulting in hospitalization (and even death, in rare cases).
RotaTeq is different from the previously available rotavirus vaccine, RotaShield®, which was withdrawn from the market due to serious side effects.

Thimerosal Content and Other Concerns
Parents who are concerned about exposing their children to thimerosal can be confident that this vaccine contains no thimerosal (a mercury-containing preservative), not even in trace amounts. Some parents are concerned about aluminum content of vaccines; this vaccine contains no aluminum.
This vaccine is not made from human fetal components, as some vaccines are. It is, however, made from bovine (cow) components.
RotaTeq is made by Merck & Co., Inc.
This vaccine is a live attenuated vaccine. This means that it contains the living virus which has been altered in such a way as to prevent it from actually causing disease. However, the body's immune system still responds to it, providing future protection from the disease.
In general, live vaccines provide better protection from infections (compared to other types of vaccines), but can also --rarely -- actually cause the disease (particularly in people who have very weakened immune systems).
