Comprehensive Value Assessments For New Pediatric Pneumococcal Conjugate Vaccines

Although the incidence of invasive pneumococcal disease (IPD) and acute otitis media (AOM) in young children has decreased since the introduction of pneumococcal conjugate vaccines (PCVs), the subsequent emergence of non-vaccine Streptococcus pneumoniae serotypes and the persistence of certain vaccine serotypes both contribute to substantial residual pneumococcal disease. There is a need for the development of new pneumococcal vaccines to address the clinical and economic burden presented by emerging non-vaccine serotypes, while maintaining suppression of serotypes in existing vaccines. To assess the full value of next-generation vaccines, public health evaluations must consider epidemiological and economic data across all vaccine serotypes, including those included in existing vaccines and those unique to the new product. This is supported by two recent analyses that estimated the health and economic burden of IPD (in the United States and Europe) and AOM (in the United States only) associated with the serotypes in V114, a 15-valent pneumococcal conjugate vaccine (PCV15), which contains all serotypes in the licensed 13-valent pneumococcal conjugate vaccine (PCV13) as well as the unique serotypes 22 F and 33 F and was recently approved for use in adults in the US. The analyses demonstrated considerable health and economic burden associated with PCV13 serotypes, as well as increasing burden associated with serotypes 22 F and 33 F. In addition to addressing the burden of non-vaccine serotypes, ability to maintain or improve protection against disease caused by serotypes in existing vaccines will be an important consideration for decision makers.
