ICER=incremental cost-effectiveness ratio. QALY=quality-adjusted life years. PCV13=13-valent pneumococcal conjugate vaccine. Hib=Haemophilus influenzae serotype b.
The market prices of non-National Immunization Program vaccines in 2019 were assumed to remain the same in the programme.
The market prices of non-National Immunization Program vaccines in 2019 were assumed to reduce by 50% after their inclusion in the programme. No changes were made to any other costs.
Costs for PCV13, rotavirus vaccine, and Hib vaccine included costs of disease treatment, indirect costs of diseases, and costs of immunisation for the 2019 cohort of newborn children. Costs for varicella vaccine included annual mean costs of disease treatment, indirect costs of diseases, and costs of immunisation in 2019–49.
QALYs for PCV13, Hib vaccine, and rotavirus vaccine were for all newborns in the 2019 cohort in their first 5 years of life. QALYs for varicella vaccine were annual mean QALY loss due to varicella disease for the entire population in 2019–49, as dynamic epidemiological modelling considered the possibility of varicella disease affecting individuals outside the vaccinated cohort.
