GSK's Boostrix wins maternal vaccination nod to protect babies from whooping cough

Slowly but surely over the last two decades, GSK has worked to give more people access to its tetanus, diptheria and whooping cough vaccine Boostrix. Now expecting mothers can pass a measure of protection to their soon-to-be-born babies. On Friday, the FDA expanded use of Boostrix (Dtap) to mothers in their third trimester of pregnancy to safeguard against pertussis (whooping cough), in infants younger than two months old.
