Information provided about group B strep Group B strep is the UK’'s most common cause of meningitis and life-threatening infection in newborn babies. About 20% of UK women carry group B strep bacteria without having any symptoms. Babies can be exposed at birth and afterwards from the mother and from other sources. Most will not develop infection but about 600–700 babies a year in the UK do. Currently, antibiotics can be given during labour if the mother is considered to be at high risk of having a baby with group B strep infection, but this does not prevent all infections. A vaccine for pregnant women to protect their babies against group B strep is being developed. This vaccine has so far been given to many adults and to a small number of pregnant women in research studies. These studies have found no evidence of harm to the women or their unborn babies and the results suggest that the vaccine could prevent most group B strep infections in babies.
