statements from Drs. Fauci and Walensky sound 'random' and confusing to the public, but that is because the disease is just that...it (as all virus do, to varying extents) mutates constantly into variants that have never been seen before...as the ID community knows too well, there is a distinct possibility that one of them could lead to an ever more deadly version with consequences for 'All' human beings and not just those over age 60. The career those Docs chose has one objective...provide services that extend lives and the quality of those lives...that's what they focus on every single day.
The reason for continued mask wearing is becaushte what Dr. Fauci said is true...we don't yet know for sure if already vaccinated people can or cannot become 're-infected'...sorry, but it is what it is. BTW, our family ICU Doc is part of a CDC program that is monitoring health care workers who have been fully vaccinated in order to help answer that very question. He gets a nasal swab for COVID-19 every day...answers a questionnaire on-line regarding his temperature and condition...and he'll be doing this for around two more years. The medical community has seen it all (Measles, Chicken Pox, Smallpox, Ebola, HIV, etc.)...they know what they're doing, so if Drs Fauci and Walensky say something, act like one of Conor's 'grunts' and say "Sir, Yes Sir"!...unless you've got someone else with more knowledge about infectious diseases.
Regarding the "lived experience" comment, I personally haven't seen or heard it...not saying it didn't happen...so I can't respond without the context. If you can point it out, I'll definitely give my 2 cents.
