Flu vaccine effective in pregnancy
Vaccinating mothers during pregnancy reduces flu among newborns by 63%, US researchers report.
Their six-month study randomly assigned 340 mothers in Bangladesh to flu or pneumococcal vaccine. It found six cases of laboratory-confirmed flu in infants whose mothers received the flu vaccine, compared with 16 in the control group.
There was also a 36% reduction in febrile respiratory illnesses in mothers and a 29% reduction in infants in the flu vaccine group.
