DTaP-IPV-HB-Hib Vaccine: an Update 10 Years After First Licensure
Abstract
Introduction: DTaP-IPV-HB-Hib vaccine is a fully liquid, hexavalent, combination vaccine that provides immunization against diphtheria, tetanus, pertussis (whooping cough), polio, hepatitis B, and invasive diseases caused by Haemophilus influenzae type b. Combination vaccines such as the DTaP-IPV-HB-Hib vaccine reduce the number of injections needed, improving both vaccination compliance and operational efficiency.
Areas covered: Safety and immunogenicity data were reviewed from >25 clinical trials involving approximately 7200 infants/toddlers, identified using PubMed searches to April 2023. These trials have evaluated a diverse range of primary series and booster schedules, including antibody persistence, co-administration of DTaP-IPV-HB-Hib vaccine with other routine pediatric vaccines, and specific populations (born to Tdap-vaccinated women, preterm, and immunocompromised infants). Lastly, post-marketing surveillance and real-world effectiveness data were assessed.
Expert opinion: An extensive program of clinical development prior to licensure demonstrated favorable vaccine safety and good immunogenicity of each antigen, and the DTaP-IPV-HB-Hib vaccine was first approved for use in 2012. In the 10 years since licensure, the DTaP-IPV-HB-Hib vaccine has been adopted widely, with more than 180 million doses distributed worldwide. The widespread use of this hexavalent vaccine is a crucial tool in the ongoing and future control of six pediatric infectious diseases globally.
