The World Health Organization (WHO) has added the R21/Matrix-M malaria vaccine to its list of ‘prequalified’ vaccines, paving the way for bulk procurement and mass deployment of the new vaccine across malaria-endemic countries by UNICEF and other global health agencies.

The prequalification of the world’s second malaria vaccine, developed by Oxford University and manufactured by Serum Institute of India (SII), is expected to greatly expand access to malaria vaccination, particularly in malaria endemic regions of sub-Saharan Africa where supplies of the already available RTS,S vaccine cannot alone meet the high demand, said WHO in a statement on Thursday.
