You're correct about the J&J vaccine; I misread its description, and I apologize. The rest of my reply stands, though. > Surely after all this time, there would be a clear winner between Modern and Pfizer, right? There's no reason to believe both products would be equally efficacious and safe over such a time period. Of course there's reason to believe they'd be equally efficacious and safe: because they're almost the same tech. It's like saying that a Granny Smith apple should have significantly different health effects as a Red Delicious apple just because they're different colors.
