That's all very sobering food for thought Frontier. Thank you for sharing that with us.
I've also been wrestling with that question as a single man if I am willing to forgo all sex for the next year and a half to two years until a vaccine is available. People are going to decide for themselves each of the sacrifices they're willing to make in exchange for being the most safe from catching Covid. And obviously not every person is going to come to the same decisions on each one.
And let's face another harsh possibility. There may not be a vaccine invented in our lifetime that gives us complete immunity to Covid. Let alone an actual cure. Colds are a virus. The flu is a virus. HIV is a virus. We have not found a cure for them after decades or even hundreds of years of trying. We have treatments for colds, treatments for HIV, treatments for flu and the medical establishment is still learning more effective treatments for Covid. But there are no fail-safe cures for any of these. Even with the flu we can say, "Oh, well we vaccines for that." And yes, they help a lot. But because viruses mutate often, each year the flu vaccine offered is just a "best guess" on the part of experts as to which strains of flu will likely be most prevalent within a certain country within the next 12 months. So even the flu vaccine is not a guaranteed blanket immunity. And the same will likely be the case for any Covid vaccine. Like many other people I have gotten the flu in the past in spite of having gotten the vaccine well in advance of infection.
Having said all that about the flu vaccine is still STRONGLY encourage everyone to get their annual flu vaccine every year regardless of its less than perfect track record of efficacy. If one's immune system (and lungs and other internal organ systems) are hit with the double whammy of the flu and Covid either at the same time or even just close together...your chances of surviving are going to be that much lower. For most of us it would be over.
