I believe the Covid Vaccination page indicated that Chrome, Firefox and Safari browsers were all supported. FYI. Safari is NOT stable. I could not create an acct with it as I couldn't get past the Date of Birth/Phone # fields. The page kept asking for correctly formatted info. The Birth Date field did not have a format guide. I had to use Chrome to create the acct.

Then, I logged into my acct with Safari and after I filled out all the info, I got stuck at the scheduling page with a spinning progress graphic.
