Antibody persistence in mothers one year after pneumococcal immunization in pregnancy.

ABSTRACT:

Background

Pneumococcal infections are a significant cause of morbidity and mortality, and young infants are particularly vulnerable to infection. Maternal immunization can protect infants, but there are limited data on the duration of pneumococcal vaccine antibody in pregnant women. We report on maternal antibody concentrations one year after immunization with 23-valent pneumococcal polysaccharide (23vPPS) vaccine.

Method

The Mother's Gift study randomly assigned 340 pregnant Bangladeshi mothers between ages 18 and 36 to receive either inactivated influenza vaccine (Fluarix(®)) or the 23vPPS vaccine (Pneumovax(®)) during the third trimester. Sera were collected before immunization, at delivery, and at one year post-delivery. We determined anti-capsular IgG antibody to 9 pne
