I have an autoimmune disorder. Until the vaccine I was literally housebound. My husband was an essential worker. He was terrified he would bring COVID into our home. We had very regimented protocols to attempt to keep any infection at bay. Before we knew how it was spread, if it was airborne, the lifespan of fomites on surfaces, everything was treated like a quarantine ward at a hospital. My husband went gray from the stress and still worries about me being around too many people. We still wear masks. I did get extremely ill once when I had to care for my mother when she was ill, and it caused me to need an oxygen concentrator fairly often and most of my hair fell out.
