There has not yet been a campaign to roll out the vaccine for malaria. There is a current effort looking at how the vaccine will be rolled out, given the fact that there isn't an adequate supply for everybody who will want it. There will be an allocation mechanism that looks at places that have the highest incidence of malaria combined with inaccessibility and therefore the most usefulness until there's more availability. We also had to do that with the COVID-19 vaccines at the beginning, when there were not enough doses available.
I suspect Lily might have some things she would want to say on this as well. I don't know if you'd like to give her a voice.
