Note that you could certainly include contributions to R&D for infectious diseases as part of the existing GWWC pledge. GWWC doesn’t have any recommendations in that area, but we certainly see it as a plausibly very effective way of helping. The same is presumably true of your other examples. Anything J-PAL or IPA promote as effective is probably well worth looking into. I personally donate to both J-PAL and IPA themselves.
