Efficacy and experience

Infanrix hexa has been shown to be highly effective against pertussis and Hib,1 and this is supported by extensive real-world evidence from a number of countries in which it is used2-5

The value of pertactin in acellular vaccines

Infanrix hexa contains 8 μg of the adhesive antigen pertactin (PRN) – more than any other hexavalent vaccine available.1,6,7 Anti-PRN antibodies have been found after natural infection and
post vaccination8 and while there is no established correlation of protection for pertussis, these anti-PRN antibodies have been linked to increased protection against the disease9

    This paper reports on a pertussis vaccine efficacy trial conducted in Germany where sera were collected from vaccinees (DTaP or DTwP) after third and fourth doses of vaccine. Sera were also collected from a randomised sample of subjects in each vaccine group at approximately 3-month intervals, from which antibody kinetic curves were constructed. This allowed estimation of specific antibody values to pertussis toxin (PT), filamentous hemagglutinin, PRN and fimbriae-2 at the time of exposure in a household setting. The imputed geometric mean antibody values to PT, PRN and fimbriae-2 at the time of household exposure to B. pertussis infection were higher (p<0.07 or lower) in non-cases compared with cases. The anti-PRN GMCs were 18.04 EU/mL for cases (33 subjects) and 36.81 EU/mL for non-cases (54 subjects)9

Proven protection against hospitalisation due to pertussis

An acellular pertussis vaccine with the same components as Infanrix hexa1 showed 100% effectiveness after a booster dose using a 3+1 schedule (N=17,856; 95% CI: 97.9–100), against pertussis hospitalisation in a population-based case-control study*15

    This population-based, retrospective, case-control study compared pertussis immunisation data of children 2.5 months to 2 years of age hospitalised for pertussis and residing in Switzerland with immunisation data of a random control sample of children aged 2 years who also resided in Switzerland.15 Vaccine effectiveness (VE) was defined as the percentage of hospitalisations avoided by number of acellular pertussis (aP) vaccine doses. VE against hospitalisation due to pertussis increased significantly with each consecutive aP vaccine dose in a “3 + 1” primary course in infants: 42.1% (95% CI: 11.3–62.6), 83.9% (95% CI: 70.2–92.1), 98.2% (95% CI: 96.1–99.3) and 100% (95% CI: 97.9–100) after the 1st, 2nd, 3rd and 4th dose, respectively15

    Hib, Haemophilus influenzae type b; PCV, pneumococcal conjugate vaccine; RV, rotavirus vaccine
    The available Hib surveillance data are influenced by country specific health policies and disease surveillance systems, diagnostic and case detection methods, and reporting processes. These factors, as well as possible changes in the casedefinition of invasive H. influenzae disease and laboratory testing methods over the years between 1999 and 2014, can all influence the accuracy and completeness of reporting, particularly when the number of cases is very low. Because of these variations, comparisons of Hib disease incidence between countries and trends over time should be interpreted with caution4
