VoICE Immunization Evidence
Impact of a maternal immunization program against pertussis in a developing country
Maternal immunization offers an opportunity to protect the mother and fetus, but also passes this protection on to the infant after birth.
Key Evidence: In Argentina, more than 50% of deaths due to pertussis occurred in infants younger than 2 months of age — too young to be vaccinated in the country. The impact of maternal pertussis vaccination in protecting their infants against the disease reduced the incidence of pertussis in infants less than 2 months old by half, when comparing states with high and low maternal vaccination rates.
