[An observation on immunization reaction and serological effect of adsorbed purified pertussis vaccine].
An observation on immunization reaction and serological effect of adsorbed purified pertussis vaccine for the first time in China had been carried out in Zhengzhou. Phase I field trial had been conducted in 8 adults and 20 children in whom there was no local reaction and temperature reaction in adults and only mild temperature reaction (37.6 degrees C-38 degrees C) in 4 children. Phase II field trial showed that the adsorbed purified pertussis vaccine manifested trivial reaction, none developed severe temperature reaction (39.1 degrees C), and 8 person-times of moderate temperature reaction (38.1 degrees C-39.1 degrees C) occurred in 100 children after 3 doses. Whereas 2 person-times of severe reaction and 39 person-times of mild reaction occurred in 101 children after receiving the whole cell pertussis vaccine. None showed local severe reaction (5.1 cm) and 1 person-time of mild local reaction appeared at 48 hours after each of 3 doses of adsorbed purified pertussis vaccine (102, 102, 98 children, respectively); Whereas, 3 person-times of severe local reaction and 17 person-times of mild local reaction occurred after each of 3 doses of whole cell pertussis vaccine (97, 100, 97 children, respectively). Satisfactory immunogenicity of the adsorbed purified pertussis vaccine was confirmed. The high serum hemagglutinin titer was achieved in 90 children, the GMT reached 817 (9.16 for preimmunization), and titers reaching 1:320 and over (a level protecting human from being infected) accounted for 84.4 percent. The average levels of anti-LPF and anti-FHA antibodies in 60 and 53 persons attained to 24.17 +/- 3.9421 EU/ml and 38.85 +/- 7.2466 EU/ml, respectively.
