Since vaccines are readily available to walkups, if someone lies about being vaccinated, doesn't wear the mask, and contracts Covid, it's their own fault.
At some point one must assign some personal responsibility.
I haven't been vaccinated yet. I was planning around fall of this year to give the vaccine more time to be studied and also to (I assume) have better protection during the time covid-19 is likely to come back (the winter).
Now I'll probably be vaccinated in the next week or so. Before this change I assumed there would be minuscule risk over the summer. Now it's been upgraded to a very slight risk. So might be worth the vaccine.
