A pharmacoeconomic evaluation of 7-valent pneumococcal conjugate vaccine in Canada

Abstract

The objective of this study was to evaluate the projected health benefits, costs, and cost-effectiveness of pneumococcal conjugate vaccination for infants and children aged <5 years in Canada. A health state model incorporating incidence, vaccine efficacy, costs, and transitional probabilities for the health states (well, meningitis, bacteremia, otitis media, pneumonia, and death) was constructed for a 10-year time horizon. Implementation of a pneumococcal conjugate vaccine program in Canada for each annual birth cohort of 340,000 persons observed over 10 years would be expected to save ∼12 lives and 100,000 cases of pneumococcal disease over 10 years, resulting in total savings of $67 million (Canadian dollars [Can$]). Vaccination of healthy infants would result in net savings for society if the vaccine costs less than Can$50 per dose. Moreover, for a vaccine purchase price of Can$67.50, infant vaccination would cost society Can$79,000 per life-year gained. Pneumococcal conjugate vaccination is a potentially cost-effective means of pneumococcal disease prevention.
