Jan 21 (Reuters) – Merck and the Coalition for Epidemic Preparedness Innovations said on Wednesday they have ‍partnered on a $30 million program to develop an updated version of the drugmaker’s Ebola vaccine aimed at improving affordability and access for low- and middle-income ‌countries.

The collaboration will work ‌to improve the manufacturing process for Merck’s WHO-prequalified Ebola vaccine, Ervebo, to increase yield and extend shelf life, CEPI said.

Ervebo’s current ​production process is complex, making it expensive and difficult to ‍manufacture at scale, CEPI ​said. The planned improvements ​could reduce costs and allow the vaccine ‍to be stored in a standard refrigerator for several months, the organization added.

Merck will work with Hilleman Laboratories on development of the updated ‍vaccine and will explore options to supply public-sector buyers in low- and middle-income countries ‍at ‍a significantly lower price ​than the current vaccine.

CEPI said ​its ⁠funding will support Hilleman’s ‌clinical development work. SK bioscience and IDT Biologika will develop the updated drug-substance process and related drug product.
