Thats remarkable, because this AM on FOX news Sunday... Chris Wallace (who I now strongly dislike because of his biased coverage) anyway, so he interviewed the Queen of Covid, CDC director R. Walensky and she didn't say ANYTHING like what you quote Fauci saying. WOW... we need to put up Fauci's comments juxtaposed w/Walensky. She kept saying "we want to leave it up to individuals to choose, mix and match is ok" NOTHING warning about specifics "rare rare" to guide the choice. Fascinating indeed. Side note: Wallace really tried to push the mRNA, and was discounting J&J, kept hounding Walensky to see if she would budge on VE (saying one better than another...but she would not). Regarding boosters: Walensky said today "We still consider double vaxed, with Moderna/Pfizer FULLY VACCINATED" W/J&J ONE DOSE PER CDC IS STILL CONSIDERED FULLY VACCINATED. The ambiguity surrounding the booster is really profound.
