re: Johnson & Johnson 1 shot vaccine shows 66% efficacy, 85% v severe disease

All the data really isn't true. Sure they have controlled all they can, however they have no idea people's resistance or reaction from Covid. We've seen that first hand without any input at all. Hell,I've witnessed it myself taking care of my son with Covid and none of us getting it. Even though there were plenty of opportunities especially right before he was positive and had symptoms.

Not sure how they can factor natural immunity into it. If they say they are 72% effective against moderate/severe disease, doesn't that sound about like where we are naturally without anything? I would say even a higher percentage than that naturally.
