I don't think this story is true( although I don't know for sure of course) as they just started a covid 19 vaccine trial yesterday in the US and they said it had been in the works for I think 65 days. So timeline wise it wouldn't make much sense.
Also although I wouldn't put it past some politicians in general( not mentioning any names, parties, , or wings so as not to be political here) the incentive for the implied action makes no sense. I.e. to keep the vaccine for one country at the exclusion of the rest of the world would guarantee the person in question would be seen as a vilan worldwide, including by most in that country.
