Sooner or later everyone is going to either come into contact and get covid, or else take the vaccine if/when it becomes available. In the meantime, take the precautions that you feel you need to, but get on with life. We can't stay hold up in our homes for the next year or so waiting on a "cure". There may never be one.
There is not a cure for the flu, just a vaccine that works sometimes, but sometimes doesn't. As far as a vaccine, what will the side effects be? Now you can get cancer from taking Zantac, an over the counter med. I don't think I'll want to take a vaccine that has been rushed through trials.
I'll be 57 this year. I have asthma, low thyroid and Rheumatoid Disease. I take immunosuppresents to lower my over powered immune system to keep it from destroying my joints & vital organs. I stayed home for over 6 weeks, and helped lower the curve. I'm not going to hide the rest of my life. I wear a mask when I have to, but I go out and do what I need to do. Will I catch covid? Eventually I probably will. Will I die from it? Only God knows. But I'm not living in fear.
