Heck, I'll be honest. Even I have had concerns about being the first in line for a vaccine, and I got an MMR booster about a month back.Yep, just do your best to buy time until a Vaccine is ready....Then, people will refuse that too!
I think when the/a vaccine eventually rolls out, its going to be similar to the early covid tests. Only the elderly, immune compromised, and first responders will get it. Then probably 6-12 months later they will open it up to the unwashed masses.
