ABSTRACT Rotarix (GlaxoSmithKline), a newly licensed rotavirus vaccine requiring 2 doses, may have the potential to save hundreds of thousands of lives in Africa. Nations such as Malawi, where Rotarix is currently under phase III investigation, may nevertheless face difficult economic choices in considering vaccine adoption.
The cost-effectiveness of implementing a Rotarix vaccine program in Malawi was estimated using published estimates of rotavirus burden, vaccine efficacy, and health care utilization and costs.
With 49.5% vaccine efficacy, a Rotarix program could avert 2582 deaths annually. With GAVI Alliance cofinancing, adoption of Rotarix would be associated with a cost of $5.07 per disability-adjusted life-year averted. With market pricing, Rotarix would be associated with a base case cost of $74.73 per disability-adjusted life-year averted. Key variables influencing results were vaccine efficacy, under-2 rotavirus mortality, and program cost of administering each dose.
Adopting Rotarix would likely be highly cost-effective for Malawi, particularly with GAVI support. This finding holds true across uncertainty ranges for key variables, including efficacy, for which data are becoming available.

    ABSTRACT: One of every 5 children does not receive basic vaccines because of concerns related to storage and delivery in resource limited countries. Transporting vaccines over long distances in extreme temperatures is a common challenge. Issues that involve production and formulation, delivery technologies, cold chain logistics, and safety factors need to be addressed to properly adapt vaccines to resource constrained settings. Current successful field interventions include United Nation Children's Fund cold boxes, which are used to store and distribute vaccine in disaster struck areas, and vaccine vial monitors, which allow health workers to gauge whether vaccine is still usable in areas with unreliable electricity and refrigeration. This review aims to provide a general overview of innovative approaches and technologies that positively affect vaccine coverage and save more lives.

    ABSTRACT: Background: Rotavirus infection is a major cause of childhood diarrhea in Libya. The objective of this study is to evaluate the cost-effectiveness of rotavirus vaccination in that country. Methods: We used a published decision tree model that has been adapted to the Libyan situation to analyze a birth cohort of 160,000 children. The evaluation of diarrhea events in three public hospitals helped to estimate the rotavirus burden. The economic analysis was done from two perspectives: health care provider and societal. Univariate sensitivity analyses were conducted to assess uncertainty in some values of the variables selected. Results: The three hospitals received 545 diarrhea patients aged55 with 311 (57%) rotavirus positive test results during a 9-month period. The societal cost for treatment of a case of rotavirus diarrhea was estimated at US$ 661/event. The incremental cost-effectiveness ratio with a vaccine price of US$ 27 per course was US$ 8,972 per quality-adjusted life year gained from the health care perspective. From a societal perspective, the analysis shows cost savings of around US$ 16 per child. Conclusion: The model shows that rotavirus vaccination could be economically a very attractive intervention in Libya. Keywords: diarrhea; rotavirus; cost-effectiveness; vaccination; Libya
