If Trump handled Covid so badly why is most of the world using USA vaccines!?

You answered your own question. The world is getting more US vaccines instead of US citizens because Trump didn't secure enough doses made by US companies.

Moderna had their vaccine completed in January of 2020, long before Operation Warp Speed started giving them wads of cash. Pfizer took no money from Operation Warp Speed even though Trump lied and said they did.

Other than canceling the USPS's initiative to mail 600 million masks to the country, other than hyping hydrochloroquine, and other than saying the pandemic would go away when it gets warm, what did Trump do?

Its very low to use covid as an attacking point.

I despise Cuomo and his liberal politically correct ideology. But when people blame nursing home deaths squarely on him is a long shot.

The virus was so new, the world has never had to adjust in such ways.
Most were learning day by day.

If there should be any anger, if anyone should face repercussions, its China.

And its very weird that most people could care less and have given China a free pass.

We’d still be 2 years away from vaccines if it weren’t for the quick action of the Trump/Pence covid task force. Period.

“We won’t have a vaccine for years” - Democrat propagandist Fauci.

We wouldn't even need vaccines in the first place if he told the truth about the seriousness of the virus in Janurary 2020 and actually made every effort to keep us safe.

Banning China from coming here isn't enough! He should have banned the US from traveling EVERYWHERE and for people in other countries to travel here. With China closed. People can still travel from China, to Europe, and then to the US and caught Covid on the way. The US needed to closed off to every country.

Probably because Trump is not a scientist, and he had nothing to do with the development of the vaccines. Where he fucked up, indisputably, was in having absolutely no plan for distribution. The fact that the US developed these vaccines is a testament to the quality scientific research and development we have in America despite 4 years of swimming upstream under a president who's allergic to science.
