This is a key statement you made:
"My family had COVID last year and honestly my wife and son's symptoms were worse than mine."
Anyone who has gone through CML - especially those who were in accelerated phase with extreme leukemic WBC counts, anemia and related and are now in remission with either very low or undetected bcr-abl had their entire myeloid blood system (and lymphocytes too!) replaced. The bone marrow went into overdrive regenerating the immune system from the few remaining normal stem cells to replace the leukemic ones.
It's like Ebeneezer Scrooge ...
Did you not know that Scrooge was one of the most generous persons to have ever lived! It's true. Scrooge gave more than any other moneyed class person of his day. So much that Tiny Tim survived. Of course we remember Scrooge differently, but that is not how he ended up. He did need a bit of help to get there (like a TKI!), but he did become a beloved figure opposite how he started out.
Same with CML. If you had/have CML - it's cancer and it must mean your immune system is weak. All true - except when it's not. Surviving CML so that our normal blood system is regenerated and makes it so much stronger than before! It's hard to fathom, but so much research is showing this to be true (Valter Longo, Ph.D, USC and others).
Add in vitamin D to activate the T-cell response (and calming after the fact to avoid hypoxia) to Covid and frankly - Covid is not an issue for CML patients in remission.
I don't have firm data, but I hypothesize that any CMl patient in remission (i.e. PCR < 0.1%) or "undetected" either hasn't had Covid or it was mild especially if vitamin D is above 55 ng/ml. I do wonder how many CML patients in remission were hospitalized with Covid. I asked my oncology doctor and he said none he was aware. He is concerned for his CLL patients.
I understand the fear. I truly do. I have a fear of heights (vertigo) - so I avoid walking bridges. Perfectly safe, but I avoid them. People wear masks. I don't unless forced. https://greatgameindia.com/list-30-studies-mask-useless-covid-19/
In 1992, George Carlin, the comedian was prophetic. Watch is "germs" skit. It's funny and it's true.
