PIN26 - A comparative public health and budget impact analysis of pneumococcal vaccines. The french case

Abstract

In 2002, a pneumococcal conjugate vaccine (PCV) was introduced to French infants and toddlers. A change has been witnessed in the incidence of pneumococcal diseases in adults: the incidence of invasive pneumococcal disease (IPD) of serotypes covered by PCV decreased, and serotypes not covered by PCV increased. This study aimed to quantify the public health and budget impact of pneumococcal vaccination strategies in at-risk adults in France over 5 years. A previously published population-based Markov model was adapted to the French situation. At-risk adults received either PPV23 (pneumococcal polysaccharide vaccine; for the immunocompetent) or PCV13 (for the immunosuppressed). The strategy was compared to PCV13 alone. Uncertainty was addressed using extreme scenario analyses. Between 2014 and 2018, vaccination with PPV23/PCV13 led to a higher reduction in terms of IPD and non-bacteremic pneumococcal pneumonia cases avoided in most scenarios analyzed when compared to PCV13 alone. For budget impact, none of ...
