Steven Salzburg certainly isn't short on hubris.

Those anti-vaxxers are just dumb, confused people.

Of course the CDC can make claims about the material not entering a cell nucleus, because AZ wasn't used in the US. I've seen people try to claim the same about AZ by referring to the CDC comments. Our own chief health officer where I live gave some botched description for three year olds about how AZ worked, then when she moved to Pfizer she was pleased to proclaim that nothing goes into the cell nucleus (knowing full well, I presume, since she's supposedly a PhD that AZ does first enter the cell nucleus).

Fuckery is everywhere.
