for those already immune. by the way, those with chickenpox are told by the cdc if you had it in the past, you should not get the varicella vaccine, it's the same immune system, it should be the same guidance. paul: so why is the administering if focusing so much on vaccinations as their great priority as opposed to a more nuanced message that says let's focus on those who don't have any vaccination and didn't have covid? >> they dug in early, and they decided that vaccinating every american was going to be the strategy that gets it of the the pandemic -- out of the pandemic. it became entrenched, and it quickly was such that any data on natural immunity threatened that position that became an edict from from on high. and as a result, i believe that they've hurt their own credibility by ignoring natural immunity. it hurt the level of honesty by public health officials.
