Interesting article. I was hospitalized a while ago for Covid Pneumonia - in hospital for 6 days - I refused the normal drugs. I had a very awake night nurse from Ukraine. I am unvaccinated. She told me that down the hall from me were 3 patients vaccinated and boosted all on ventilators - I was blessed to have her..she helped me heal quickly with simple breathing exercises to help me reduce my temperature so I could get out.
