R21 is good, the case for going faster is ethically strong and is pretty well articulated already, making this a relatively easy lift. Concerns around relative cost effectiveness vs other malaria control measures (e.g. bednets, SMC) are reasonable questions to raise but largely irrelevant for this given the proposal is to accelerate something that will happen anyway, the funding for delivering a malaria vaccine is largely secured already (via Gavi, Global Fund, national governments) and is unlikely to meaningfully funge more cost-effective alternatives. R21 is much cheaper than RTS,S, and almost certainly more effective.
In the spirit of quick answers, yes
