Disregarding a way to accelerate vaccine development by months, and save literally hundreds of thousands of lives along the way, because one thoughtlessly applies cliches like "you are supposed to not make people ill", even though the people who you make ill are all volunteers, well aware of the risk, and handsomely compensated for it, is the real total ethical failure.

It's as if when there are some "professional" ethicists in the area who give "professional" ethical guidance, people lose their natural moral sense, and defer to their "professional" guidance no matter how silly it is if you apply even modicum of scrutiny.
