These two studies are not normalized on time so slightly more events in ~two months for A vs B verse a lot more in ~one month for C vs D means more total events

These two studies are not normalized on time so slightly more events in ~two months for A vs B verse a lot more in ~one month for C vs D means more total events in A than C. Really, if you believe the primary difference is that pfizer was a lower dose and that this isn't all just noise, the data seems to be showing that there's a pretty short window where the risk of the jab wasn't made up for by benefit such that a longer study lost ground on finding a measurable risk.
