Compared with unvaccinated subjects, the vaccine effectiveness (VE) of 4 doses was 70% among all subjects and reached to 90% with marginal significance among subjects under 6years of age. However, among school-aged subjects, the VE was not suggestive of protection against pertussis (VE 8%). For vaccinees given 4 doses, the OR for developing pertussis increased significantly with longer duration since the fourth dose (compared with 4.5years, OR of 6.0-8.2years=5.74; OR of ≥8.3years=3.88; P for trend by duration0.01).
