| PICO Question: Among healthy newborns does immunization with acellular pertussis accelerate vaccine-induced immunity (or immunologic tolerance) against pertussis? Question type: Intervention Study design: Prospective, double-blind, controlled trial
|
To assess the effect on subsequent immunity resulting from pertussis immunization in newborns, investigators from the Childrens Hospital, Mainz, Germany; GlaxoSmithKline Biologicals; and the University of Geneva, Switzerland, conducted a double-blinded, randomized control trial in healthy neonates vaccinated during the first week of life.
Study infants were born after an uncomplicated 36- to 42-week pregnancy with a birth weight
2,500 grams and a 5-minute Apgar
7. Infants were randomized to receive one dose of either trivalent acellular pertussis (aP) vaccine or hepatitis B (HBV) vaccine at 2–5 days of age. Subsequently, all infants received vaccination with DTaP-HBV-IPV/Hib at two, four, and six months of age.
Overall, 121 neonates were enrolled in the study; 60
