Maternal pertussis vaccination can protect premmies
VACCINATION of pregnant women against pertussis early in the third trimester protects premature infants.
UK researchers say while it’s known that antenatal vaccination leads to transfer of maternal antibodies, the benefit is limited by premature birth.
A study of 160 premature babies shows that among the 19% born to vaccinated mothers, there were significantly higher antibody concentrations at two months for all the measured antigens.
After their first shot, babies of vaccinated mothers had a lower immunologic response than those born to unvaccinated mothers.
