Why is the R21/Matrix vaccine a game-changer?
We’re seeing about 75% efficacy by counting the reduction in numbers of malaria episodes over a year. The best vaccine prior to this was about 50% over a year, and lower than that over three years.
This is a material improvement, but that’s not the main improvement. The big difference is how you can manufacture it at a scale that is really needed to protect most of the children who need a malaria vaccine in Africa.
