Bourla said this awhile ago, explaining how his own R&D team pushed the mRNA technology on him though he was skeptical. This is not a new position for him -- but he took their advice and "followed the science" he was told would work, without proper testing and with skewed reporting of trials that were done. So he knew or should have knew the mRNA vaxx was a sham. He went with it, either with knowledge or because he is a dimwit. Neither excuses the CEO of Pfizer who is paid extraordinarily well to run the company.
