A randomised controlled study of the reactogenicity of an acellular pertussis-containing pentavalent infant vaccine compared to a quadrivalent whole cell pertussis-containing vaccine and oral poliomyelitis vaccine, when given concurrently with meningococcal group C conjugate vaccine to healthy UK infants at 2, 3 and 4 months of age.

Two hundred forty-one healthy infants were enrolled in an open randomised controlled study of three doses of DTaP-IPV-Hib (Group 1) or DTwP/Hib+OPV (Group 2) at 2, 3 and 4 months of age given concurrently with a meningitis C conjugate vaccine. After each dose, local reactions (any grade) were less common in Group 1 than Group 2 (p<0.03). Axillary temperature >37.5 degrees C, decreased feeding, reduced activity, irritability and crying in the week after vaccination were also less common in Group 1 than Group 2 (p<0.05 for each symptom, all doses combined). Severe local reactions and systemic symptoms were uncommon and occurred equally in both groups. The pentavalent DTaP-IPV-Hib vaccine was less reactogenic than the quadrivalent DTwP-Hib vaccine, as expected when changing from whole cell pertussis (wP) to an acellular pertussis (aP) component.
