Reuters failed to report in that paragraph that Cain had been suffering from cancer for years. It was known early own that Covid 19 was more deadly for those with cancer because their immunity was already suppressed due to treatment. However, the doctor advised my mother NOT to get the vaccine because of her cancer. So, I think it was 50/50 either way.
This Covid denial is silly. It's killed a lot of people, a lot more than the flu. That is why every nation on earth has taken severe precautions to stop its spread.
