Babies born via cesarean section may not mount as strong an immune response after some childhood vaccines compared to babies delivered vaginally, researchers suggest.
Antibody levels can be checked in blood or saliva, and babies born vaginally had higher levels of antibodies in their saliva to pneumonia shots at one year and meningococcal shots at 18 months, a new study showed.
But the study authors are quick to caution that their findings are not a reason to skip recommended childhood vaccinations.
