China, Cuba and Russia made their own vaccines though and are doing fine with them.
China is 71% fully vaccinated (76% first dose), Cuba 44% (79% first dose), Russia behind at 29% (33% first dose).
The USA sits at 55% fully vaccinated (64% first dose) but does lead in total doses 391 million administered.
Capitalism doesn't seem to be much different when it comes to a fast rollout. Actually all the checks and balances to keep capitalism in check were the biggest hurdle and without governments making concessions there we would still be waiting for approval.
And it leads to this kind of crap
