I don't know what the answer is as far as why one person contracts an illness and is back to normal in a couple of days while another person of similar health, weakens and dies. Immunocompromised folks seem to be the most at risk. But, whether or not a person gets vaccinated or not, it is none of my business. If they do, that's fine, if they don't, that's fine too. I don't expect an explanation as to why they did get the vaccine or why they won't. All public places here in Tucson require a mask. We've had a real spike in AZ of cases recently. Very few ICU beds are available, and Monday, I saw the morgue trucks coming back in town, heading toward the hospital which is not far from our home.
As far as the federal government is concerned, I very low opinion of them, regardless of party. I read information researchers release about the virus, but little current, definitive information is available. Before I became a CPA and Attorney, I studied biochemistry and zoology at Texas. In labs, we were amazed at how fast the viruses could mutate, and the cells that could not be infected the first time, were easily compromised a week or two later. Since then I have always tried to keep my immune system in good shape. Does that mean I won't contract the new D1 strain and die? No. Anything is probable, but I can only try to keep that probability as low as I can. What other people do, is none of my concern. They don't live with me.
