Will there be an option to donate to the specific cause of distributing malaria vaccines, especially R21 Matrix M?

I've donate to the "Against Malaria Foundation" since they are recommended by Give well and could save a life for 5000 US$.

The newly approved R21 Matrix M vaccine has a proven 18 months efficacy of about 75% when given with a booster shot. Comparison: the earlier Version "RTS,S" has something like 30%.

The WHO now recommends the new vaccine and GAVI (the vaccine alliance) has launched a rollout program, with the first shipment arriving last month in the Central African Republics capital Bangui.

Will this cause GiveWell to reevaluate its non-recommendation of GAVI?

Or will they find another charity that distributes R21 more effectively?

Resolution criteria:

1. "Soon" = in three months on 10th September.

2. A charity is recommended by GiveWell that distributes R21 Matrix M (other Vaccines like RTS,S don't count).

3. The charity has to have a program to specifically donate R21-Vaccines, general "malaria vaccinations" don't count if I have to assume that part of the donation goes to RTS,S.

4. The charity doesn't have to be amongst the top charities. Just a recommended one.

Market conditions:

1. I haven't looked to deeply into the topic as of yet. E.g. I haven't sifted through GiveWell recommendations fully. So if you are willing to: here is your chance.

2. I am only aware of GAVI right now. But that is because I started my search at the WHO.
