I am a retired RN of 43 years experience. I have several comorbidities and have been isolated since this has started. With everything that has been said and all the research that has been done, there is still so much that is unknown about Covid-19. My wife has been the one who has gone out into the world to do the things that need to be done. She is always masked with an N95 and gloves and an overcoat. She strips down in the basement and showers down there before coming upstairs. I am afraid I will always be isolated for my own safety because it may not be possible to develop a vaccine. I never thought my life would take a turn like this in my retirement years. It is frightening to think about.
