Wtf are you talking about? Are you talking about vaccine development? Because currently zero countries have a working vaccine yet, the most promising ones are still in phase three testing. As for development, OF COURSE other countries are developing vaccines. News flash: it's a global pandemic, everyone is trying to develop a vaccine.
And if the US does develop the covid vaccine first, that's not because of Trump's genius, it's because of the US's status as a first world country and its strong medical innovation infrastructure.
