No one is calling anyone an idiot. It's a personal choice. But I don't agree that it is "experimental". They have a lot of SARs data and they used it to formulate the current vaccine.
At one time, the polio vaccine was "experimental" - two different teams came up with two different vaccines from two different approaches. Salk got his to market quicker and people lined up to take the shot - because they figured it was a better deal than to get polio. Every vaccine and medication is to some extent "experimental" - you know in all those drug adds and they list all the possible side effects? Someone experienced those when they took the medicine, yet most of the users will not get them.
In my view, "perfect" is the enemy of "good". And lives are being saved. And those nurses who aren't taking the vaccine- I don't want them anywhere near me, and in my opinion, they should be prevented from working with patients
