Flu Shot During Pregnancy Protects Newborns

Recent research indicates that flu vaccines given during pregnancy can protect newborns against the flu. However, the length of protection against the flu in infants has been unclear, until recently. A new trial involving over one thousand babies, compared babies born to mothers who received the flu shot to babies whose mothers received a placebo during pregnancy. Blood samples of both newborns were taken periodically between seven days and twenty-four weeks after life to determine the level of protection against the flu virus. Results of the study showed that flu shots given to mothers protected most infants in the first two months of life.

The flu is a contagious respiratory infection caused by different influenza viruses. A yearly flu shot is considered by health experts as one of the best ways to lower the chances of getting the flu. Some side effects of getting a flu shot include soreness, swelling, fever, and aches. These side effects are usually short-lived and mild.
