Personally I feel, insuring individuals against COVID-19 or helping people to get vaccines or sending other supports can be better handled locally by local affiliates (or local committees as proposed by Tito, whichevers seems fit) instead of a central organization like WMF. Local affiliates have better information about the vulnerable section of the community, government orders concerning the available vaccines, local market value of insurance premiums, vaccines, disinfectants etc. Sometimes they even have the money and/or the intention to extend this kind of support too, all they need is just a permission from the donor i.e. WMF Grants team.
