The R21 malaria vaccine, which is also known as Matrix-M, was designed at the Jenner Institute, University of Oxford, which collaborated with SII in 2020 to manufacture and develop the jab for large-scale supply.
Malaria killed more than 620,000 people in 2020 and sickened 241 million, mainly children under 5 in Africa. The World Health Organization is rolling out the first authorized malaria vaccine for children, but it is about 30% effective and requires four doses.
