How you're born alters vaccines' power

How you're born alters vaccines' power How we are born - by Caesarean-section or vaginal delivery - alters how our immune system responds to vaccines, a Scottish and Dutch study suggests.

Babies born vaginally had double the level of protective antibodies produced after childhood vaccines.

The researchers said the difference was caused by the types of good bacteria, which colonise our bodies at birth. BBC News
