Lets see, it was a scientist from China who decoded the viruses DNA and made the information public to speed up the vaccine creation (at the cost of his job btw because f**k the China government), it was a German pharmaceutical company that developed the vaccine, and now the vast majority of said vaccine is currently being produced in European.
How was Trump any part of this? Oh right, he denied the virus's existence, told people to ignore the science because it was counter to his opinions, promoted a potentially dangerous if miss used drug as a "merical cure" because he had stock in the company that produced it, then refused to purchase more of the vaccine when he had the chance because he was holding out hope a different company he owned stock in would make one so he could promote that one instead thus severally delaying and hindering the vaccination effort while also refusing to provide states with any sort of aid in actually distributing the vaccines they already have meaning the ones we do have are now at risk of expiring before they even have a chance to be used.
