There is currently no flu vaccine for babies under six-months-old, but babies in that age group are more likely to be hospitalized for the virus than any other age group.
Doctors tested the theory by administering flu shots to pregnant women in Bangladesh. There was a 63 percent reduction in flu among babies whose mothers were given a flu shot.
Parents can also protect their children by getting the shot themselves, which reduces the chances they will spread the virus to other vulnerable family members.
