I just scheduled mine for the 22nd. Talked to my nurse practitioner and she referred me to the county health people. Went there and they gave me a card with how to schedule it and I did.The link in the OP reminded me of the Tom Clancy novel Rainbow 6.
I'm going to talk to my nurse practitioner today about getting the shot. I'm over 65 and I have diabetes, so that is two high-risk factors for me.
You have to call or email the state health folks and I filled out the online form and I chose where I'd get it and when.
