I have a friend who chose not to get vaccinated. She has been in the hospital since Friday. Her O2 sats were in the 80s. They had her on oxygen and on her stomach in a general med room. At least she is not in ICU - yet. She had been a care giver for my mother and for 2 1/2 years spent two nights a week at my mother's house helping with my mother's dialysis.
When it comes to COVID-19, there really is no one you can completely trust. Completely trust when they say that they take all the precautions all of the time. People are well-intentioned, but forgetful, or maybe just don't completely get it. Even our household members - we don't know what each one was exposed to during the day, and then the family is all together at home. I've watched my masked spouse stand next to an unmasked man looking under the hood of a vintage truck. They chatted at least 5 minutes. ( My observation is that people who don't wear masks usually aren't vaccinated.) Spouse also drove with his son to get take out food. A week later, his son was sick with a "head cold". Who gets colds this time of the year? It was too inconvenient to drive a few miles to get tested before he drove to Southern CA to visit family there. Spouse and I got tested. We were negative - maybe son really did have just a cold.
I admit to engaging in risky behavior too. I've hugged a few friends I ran across - vaccinated, masked friends. But that too, is taking a risk. I hugged my vaccinated neighbor when she knocked on my door with a potted plant she gave me upon learning that my mother had passed away. I had a mask on, but she didn't. A week ago I talked with her and her husband who were on a walk. She had gotten COVID-19 and had a mild case since she was vaccinated. What if she had been sick when I hugged her? I think I'm through hugging people....too risky.
