Infants and young children are at particular risk of contracting pertussis until they have completed their primary immunization series. For maximum protection, children need a primary series of pertussis-containing vaccine at two, four, and six months followed by booster doses at 18 months, between four to six years of age, and again as part of the school-based immunization program, which in Nova Scotia, occurs in Grade 7.
The best way to prevent mortality and significant morbidity from pertussis is for health care providers to:
- offer one dose of pertussis containing vaccine (Tdap) to all pregnant women, ideally at 27-32 weeks of gestation. An earlier gestation may be chosen in some circumstances;
- ensure that infants and young children are immunized according to the recommended schedule; and
- recommend that caregivers and close contacts of infants and young children receive a pertussis immunization.
