“…7 , 8 , 9 , 10 Short-term protection afforded by pertussis vaccines depends on the number, timing, and interval between doses. 11 Thus, strategic scheduling and timely uptake of boosters is crucial. Longer intervals between doses due to delays or missed immunizations could increase pertussis risk even in partially vaccinated children.…”

Key Points Question Are undervaccination and delay in vaccination with diphtheria-tetanus–acellular pertussis (DTaP) vaccine associated with pertussis risk in infants and young children? Findings In this population-based cohort study of 316 404 children, those who were undervaccinated for the primary series, second-year booster, and preschool booster of the DTaP vaccine had 4.8-fold, 3.2-fold, and 4.6-fold higher pertussis risk, respectively, compared with fully vaccinated children. Doses administered with a short delay were not associated with pertussis risk. Meaning These results suggest that young children should receive DTaP doses in an age-appropriate and timely fashion as recommended by the Centers for Disease Control and Prevention for best protection against childhood pertussis.

“…The accelerated schedule consists of 3 doses of vaccines in the first 6 months of life whereas the 3 doses of vaccines in the long schedule are given in a span of 11 to 12 months [52]. The immunization schedules vary among countries using the same type of vaccine.…”

“…Studies conducted in the 1990s did not offer conclusive evidence. Some studies suggested higher serological response using the long schedule [53,54]; however, no good serological correlate of protection has been identified [52]. Systematic review also found no good data for the comparison of different schedules in terms of effectiveness [52].…”

“…Systematic review also found no good data for the comparison of different schedules in terms of effectiveness [52]. Besides, the evidence of the age of infant immunization initiation having an impact on immunogenicity or effectiveness is limited [52]. Under such circumstances, the observation of the variation of infant immunization schedule further supports the hypothesis that pertussis immunization strategy is influenced by factors other than existing evidence in efficacy or effectiveness.…”

Pertussis vaccination policy varies across Europe, not only in the type of vaccine (whole cell (wP) vs. acellular (aP1/2/3/5)) but also in the schedule and recommendation for parents. This study aims to investigate the determining factors for the type of vaccine, immunization schedule and maternal immunization recommendation. From March to May 2019, experts in national health agencies and major academic or research institutions from Denmark, France, Poland, Sweden and the UK were invited to a semi-structured interview. Thematic analysis was performed on the transcripts using a codebook formulated by 3 coders. Inter-coder agreement was assessed. Fifteen expert interviews were conducted. The identified driving factors for pertussis vaccine policy were classified into three domains: scientific factors, sociological factors, and pragmatic factors. The determining factors for the type of vaccine were prescriber preference, concern of adverse events following immunization (AEFI), effectiveness, and consideration of other vaccine components in combined vaccines. The determining factors for infant schedule were immunity response and the potential to improve coverage and timeliness. The determining factors for maternal immunization were infant mortality and public acceptability. To conclude, socio-political and pragmatic factors were, besides scientific factors, important in determining the vaccine type, schedule of childhood immunization and recommendations for parents.
