or Trump as he has announced the US will not be joining COVAX, a global initiative aimed at working with vaccine manufacturers to provide countries worldwide equitable access to safe and effective vaccines, once they are licensed and approved - though to be fair "medical experts" don't necessarily all agree that COVAX's policies are the only, or even the best, ways of ensuring the most "equitable" distribution of vaccine doses! though Trump's response seems to be solely based on WHO involvement!

one of the analogies I have seen is if you desperatly want a pizza delived within a very limited time frame ordering from multiple pizza places is more likely to ensure success - perhaps a bit simplistic because if a pizza from you preferred supplier arrives cold, half cooked or missing most of the toppings it is perhaps salvagable, but more of a problem for a vaccine that turns out to be not effective or causes serious side effects!
