Vaccinating pregnant women saves babies from flu

INFANTS younger than six months whose mothers are vaccinated against influenza  in pregnancy have an 80% reduced relative risk of being hospitalised with flu, a study shows.

The US research, from Utah, compared babies born to more than 23,000 women self-reporting influenza vaccination in pregnancy with those of 222,000 women not reporting vaccination.

In one of the few studies to evaluate infant influenza outcomes among vaccinated vs non-vaccinated pregnant women, the authors analysed medical records from mothers and babies across nine flu seasons.
