Mariupol

?? Polio isn't in Africa anymore because of those efforts. The only places where it is active are areas that actively resist against vaccination efforts like in Taliban controlled Afghanistan and Pakistan

IIRC he's matching donation money for Rotary International's effort in polio eradication. This is essentially a tax write-off, though the cause that it is going to is good and the amount is reasonable given the fact that it is extremely difficult to eradicate a disease

No, more like "listen up you dumb ass Taliban regional leaders. This vaccine won't make your populous believe in satan and do immoral acts, it means they won't die or be crippled by a preventable disease"... so pretty much the same strategy for anti-vaxxers

Are you talking just about the western world because it's still a problem in parts of Pakistan and Afghanistan due to lack of vaccination
