Epidemiology of pertussis in Denmark : the impact of herd immunity.
An evaluation is presented of the Danish pertussis immunization programme, which consists of three injections of plain whole-cell pertussis vaccine given alone at ages 5 weeks, 9 weeks, and 10 months.
The incidence of pertussis in vaccinated and unvaccinated children since the start of vaccination was obtained from the notification system for infectious diseases.
Data for vaccination coverage were obtained from the National Social Security.
The data for 1980-1986 were supplemented with data from culture-verified cases and hospitalized cases.
Compared with other countries using four injections, incidence rates in Denmark are high, especially in preschool years, leaving infants at a relatively high risk for contracting pertussis from siblings.
