Post-vaccination symptoms following DTP and DT vaccination
Abstract:
Post-vaccination symptoms in 6,004 infants given adsorbed Diphtheria Tetanus and Pertussis (DTP) vaccine and 4,024 infants given adsorbed Diphtheria and Tetanus (DT) vaccine have been compared. Although crying, screaming and fever were slightly more frequent after adsorbed DTP than adsorbed DT, attacks of high-pitched screaming, episodes of pallor and hypotonia, convulsions, other neurological disorders and sudden infant death occurred with similar frequency in the two groups. No specific neurological effect attributable to the pertussis component was found.
