Nope, it was medical advances, specifically the mrna vaccinations which are doing that, although the 'rona will probably never be eradicated [unlike smallpox] ...

During the covid pandemic trump was, tbh, a great liability, and his stupidity / self-centredness [like bojo's] probably exacerbated the situation & may have caused a lot of the deaths which could / should have been avoided.
{Yes, I'm bitter - I lost family & friends to 'rona}
