ON something non covid, my sister 64 ( retired 2 years @ Hospital Director of nursing) took a cruise, and came home and 5 days later felt like crap. Felt like she had cold, congestion, runny nose, sore throat, a fever. Went to the doctor, they ran a Rapid RSV antigen test, she had caught RSV. This stuff is fast and it got into the chest. They got her on some type of antibiotics and 10 days on steroids and finally after 3 weeks she is starting to feel better. She called and asked if I got the one time RSV shot, I said no, she said do it. So that's my plan on Monday. With all of my past medical issues I sure don't need some deep chest infection that could led to crippling lung issue.
