Good luck, Rosemary. Ironically, I was just on the Rob Relyea website https://covidsafe.fyi/evusheld/ which he created earlier because he and his wife had similar difficulties. There is a Geekwire story on Relyea and Atlantic magazine write up on the challenge for immunocompromised people.
So. I got my first shot in August after I contacted our hospital's president, whom I'd worked with on some workshops on Medicare, and asked why no Evusheld. They got on it, ordered some, and I got the shots. This morning when I went back. My county was not on the list. Go figure. My transplant center in Madison had a lottery for their shots. That's why I wanted to get it locally here. I'm due for the 2nd series in March. I guess the Feds only bought so much of this from Astra Z. Maybe they are running out. Anyway. People can check this website for updates on where they can find Evusheld. You'd think AZ would provide this kind of service.
