Immunogenity and antibodies persistance of diphteria-tetanus-acellular pertussis vaccination in adolescent and adults: a sistematic review of the literature showed different response to the available vaccines

Introduction: In industrialized countries, routine use of pertussis vaccines has shifted the burden of pertussis disease from children to infants, adolescents and adults, leading to the necessity of booster doses. Materials and methods: We prepared the review following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) with the aim of a) to describe the immunogenity of the main available vaccines for adolescents and adults b) to describe antibodies persistance after immunization with the main vaccines available in childhood and adults and, also, possible co-administration and c) to identify the gold standard for adolescent and adult immunizations. Results Of 6906 records identified, after removing duplicate records, 12 RCT were included (people aged 11-73): of these 7 studies had only 1 control group, 4 studies had 2 control group and 1 had 5 control group; moreover of the 12 studies included only 2 regarding co-administration and all were about immunogenity. 9 out 12 studies had a Jadad score above 3 points and 10 out 12 meet the criteria of Cocrane Back Review Group Criteria List for Methodological Quality Assessment. Discussion and conclusion: We found a limited number of good-quality RCTs investigating our object. The five component vaccines, although containing a lower dosage of antigen, are found to be more effective than one components vaccines for prevention. Evidences support the use of 5-components vaccines for booster sessions in adolescence and adulthood.
