Leveraging mRNA Platform Technology to Accelerate Development of Vaccines for Some Emerging and Neglected Tropical Diseases Through Local Vaccine Production

The mRNA vaccine technology platform may enable rapid response to some emerging infectious diseases (EIDs), as demonstrated through the COVID-19 pandemic. Beyond the role it could play in future EID response, mRNA technology also could have an important role in accelerating the development of, and access to, vaccines for some neglected tropical diseases (NTDs), which occur mainly in impoverished regions of the world. Despite their significant disease burden, few vaccines against NTDs have been developed, in part because of the uncertain market and return on investment. In addition, the probability of technical and regulatory success is considered to be low for developing vaccines against multicellular parasites, or organisms that have sophisticated mechanisms for evading immunological surveillance, such as many of the NTD pathogens. The global 2021-2030 road map for neglected tropical diseases sets ambitious targets for the eradication, elimination, and control of NTDs. For some, effective interventions exist but are underutilized. For others, vaccines need to be developed or their use expanded to meet global targets on control and elimination. This article discusses the application of the mRNA technology platform to the development of vaccines for NTDs as well as EIDs, highlights the challenges in bringing these products to the market, and indicates potential areas which could be explored, including leveraging investment for vaccines with a more profitable market potential and enabling local manufacturing in regions where NTDs are endemic. Such regional production could include collaborations with the mRNA vaccine technology transfer hubs that are being established with the support of WHO and COVAX partners.
