Curapath Announces Collaboration with Afrigen Biologics to Advance Development of African-owned mRNA SARS-CoV-2 Vaccine

Curapath will develop and optimize a process to produce a nanoparticle formulation for the vaccine Valencia, Spain and Boston, MA, November 16, 2022 – Curapath, a leader in the design, development, and custom manufacturing of polyamino-acid- and lipid-based nanoparticle delivery systems for therapeutics and vaccines, today announced a collaboration with Afrigen Biologics to advance the development of the first African-owned mRNA SARS-Cov-2 vaccine. Under the collaboration, Curapath will be responsible for development of a scaled-up manufacturing process of the nanoparticle formulation for the vaccine and will assist in developing the fill/finish process. Afrigen Biologics leads a South African-based mRNA technology transfer hub consortium, supported by the World Health Organization (WHO) and established to address concerns that less affluent countries were not getting sufficient access to vaccines against COVID-19. The goal of the WHO vaccine initiative is to help manufacturers in low- and middle-income countries produce their own Covid-19 vaccines and eventually, produce other vaccines and therapeutics using the mRNA platform, reducing reliance on pharmaceutical companies in high income geographies. The goal is to build capacity in low- and middle-income countries by transferring technology and know-how to a network of recipients (spokes) through a center of excellence and training such as
