Why are American's so stupid about COVID-19?

Where I work, we are being offered (voluntary) one of the first two vaccines to receive emergency use authorization in the United States.  A co-worker in my section was asked to add us all to the spreadsheet used to track who will take it and who won't.  After the spreadsheet was filled out, I discovered to my amazement (and horror) that I was the only person among 8 in my section who volunteered to get vaccinated.

I asked a few people I work with, why they are NOT getting vaccinated. 

1)  My boss said, "the virus is a hoax".  (I wish I'd made that up)

2)  My first co-worker I asked said, "My wife is a nurse and she advised me not to get vaccinated."  I asked him for more details, and he went on to explain...since they don't have a vaccine for CHILDREN yet, the adults in his family are waiting for a vaccination that the whole family can take.

3)  Second co-worker I asked said "They are experimental vaccines, and not approved by the U.S. FDA"

Holy Crap. 

1)  I can't comment on "hoax" bit, as it's too stupid to make an effort...

2)  A NURSE doesn't understand the concept of community immunity?????????

3)  Because I've lived overseas for many years, I am fully aware that many of the best medicines in the world are not U.S. FDA approved...and they never will be.  This first came to my attention when I ran out of my anti-depressant (used for migraine prevention) and my Asian doctor laughed at my U.S. prescription, calling it obsolete by decades... (but it was FDA approved!!!)
