William Makis lost his license to practice just before covid.

He seems to have decided to sell snake oil to anti-vaxxers to make up for his lost income. He tried to claim doctors were dying from covid vaccines but a) provided no proof, and b) included people who died in car crashes and drownings, pre-existing heart and cancer problems, and - famously - one who fell off the world's 2nd tallest mountain.

But he's good enough for Bullshityouharder folks.
