Overview
Recent modeling studies assess the potential benefits of introducing the neonatal RV3-BB rotavirus vaccine in Malawi and Ghana, where current programs use Rotarix and Rotavac vaccines.

Why now
- New modeling data provide updated estimates on vaccine impact and cost thresholds for next-generation vaccines.
- Ongoing efforts to expand rotavirus vaccination coverage require evidence to support policy decisions.
- Emerging vaccines like RV3-BB offer potential improvements over current options, warranting timely evaluation.
Why it matters
- Rotavirus remains a major cause of infant morbidity and mortality in LMICs, necessitating improved vaccines and strategies.
- Cost-effectiveness analyses guide resource allocation for vaccine introduction in resource-limited settings.
- Optimizing vaccination programs can substantially reduce disease burden and improve child health outcomes globally.

Recurring claims
- The neonatal RV3-BB rotavirus vaccine may be cost-effective in Malawi and Ghana if priced below $1.2 and $2.5 per dose respectively and if protection lasts over 40 weeks.
- Expanding rotavirus vaccination coverage, adding doses, and introducing vaccines in countries without programs can significantly reduce rotavirus cases, deaths, and disability-adjusted life years in LMICs.
