Description:Background:
Although use of the 13-valent pneumococcal conjugate vaccine (PCV13) among children has reduced incidence of pneumococcal disease, a considerable burden of disease remains. PCV15 is a new vaccine that contains pneumococcal serotypes 22F and 33F in addition to serotypes contained in PCV13. To inform deliberations by the Advisory Committee on Immunization Practices on recommendations for PCV15 use among U.S. children, we estimated the health impact and cost-effectiveness of replacing PCV13 with PCV15 within the routine infant immunization program in the United States. We also assessed the impact and cost-effectiveness of a supplementary PCV15 dose among children aged 2–5 years who have already received a full PCV13 series.
Methods:
We estimated the incremental number of pneumococcal disease events and deaths averted, costs per quality adjusted life-year (QALY) gained, and costs per life-year gained under different vaccination strategies using a probabilistic model following a single birth cohort of 3.9 million individuals (based on 2020 U.S. birth cohort). We assumed that vaccine effectiveness (VE) of PCV15 against the two additional serotypes was the same as the VE of PCV13. The cost of PCV15 use among children was informed from costs of PCV15 use among adults and from discussions with the manufacturer.
Results:
Our base case results found that replacing PCV13 with PCV15 prevented 92,290 additional pneumococcal disease events and 22 associated deaths, while also saving $147 million in costs. A supplementary PCV15 dose among children aged 2–5 years who were fully vaccinated with PCV13 prevented further pneumococcal disease events and associated deaths but at a cost of more than $2.5 million per QALY gained.
Conclusions:
A further decrease in pneumococcal disease in conjunction with considerable societal cost savings could be expected from replacing PCV13 with PCV15 within the routine infant immunization program in the United States.
