In a perverse sort of way, the fact that Fauci seems to have a bias against the JNJ/Janssen vaccine makes me trust it the most ;-)
Back when they launched, I figured the JNJ would be by far the most widely deployed. One and done, not mRNA, and much easier to distribute and store in a regular medical refrigerator. But then they pulled it from the market for 4-6 weeks; that on top of production and supply problems put a pall over it.
FWIW, I spent nearly the whole day yesterday helping a friend try to get the JNJ vaccine. We called the pharmacy where another person got the JNJ vaccine 2 days earlier, they said they had it but when we showed up they said they had no vaccines at all. Went to another pharmacy only had Moderna. Called Wal-Mart, directed to some hotline for vaccines and the guy on the phone told us the two closest to us had no inventory but one had all 3 in stock. We drove there but when we arrived we were told they had zero of anything in stock but said come back tomorrow they were expecting a shipment but didn’t know which vaccine would come in the shipment (I imagine WalMart has better logistical information on graham crackers than they do the vaccine). Went to another Wal-Mart same story. Went to Walgreens, nothing in stock. Went to another pharmacy, only Moderna. We decided to call it quits and drive her home, but a lark we passed a supermarket so why not walk in and check. They had it, had dispensed 3 of the 4 doses from the vial so one left. Hurrah! But, the pharmacist came back and said “sorry, it expired 45 minutes ago we have to throw it away, but come back in the morning and we’ll break open a fresh vial”.
