Abstract
This study aimed to evaluate the cost and effectiveness of introducing a live, attenuated vaccine (SA 14-14-2) against Japanese encephalitis (JE) into the immunization program. The study demonstrated that SA 14-14-2 immunization is cost–effective in controlling JE in Cambodia compared to no vaccination. Averting one disability-adjusted life year, from a societal perspective, through the introduction of SA 14-14-2 through routine immunization, or a combination of routine immunization plus a campaign targeting children 1–5 or 1–10 years of age, costs US$22, US$34 and US$53, respectively. Sensitivity analyses confirmed that there was a high probability of SA 14-14-2 immunization being cost–effective under conditions of uncertainty.
