If anyone wants to go into more detail, here's my related market:

I assume if one or more vaccines are banned this resolved "YES", not all vaccines have to bed banned as a category, correct?

@Enlil If we interpret it broadly enough, every administration that has held or denied FDA approval for a vaccine has "banned vaccines".

I propose a vaccine basket: pneumonia, covid, flu, hpv, and hepatitis. If one of those is categorically illegal, resolves yes. Otherwise, resolves no even if some vaccine somewhere had its FDA approval revoked.

@GG it seems the most likely candidate for a ban would be COVID vaccines
