I look forward to reviewing Robert Malone’s article but anecdotally I believe my husband and I had the initial strain ( Wuhan) January 2020. He got vaxed in March; I did not for medical reasons. In May we had unconfirmed Delta. The symptoms came on fast at almost the identical time and lasted for a duration of 3-4 days. His symptoms were a little worse but I took zinc. He didn’t. Since then we recently had a mild cold - his was worse with a cough and he caught it first, but both of us had colds that were short and mild. We tested for omicron but the results were negative; we never had muscles, fever or sore throat. All of our vaxxed friends have had Omicron. So I would say even tho my husband was infected then got vaxxed, he seems to be doing ok now from an immunity point of view. We do take lots of supplements though.
