They stopped it in my state as well but the reasoning isn't absurd. I believe they are 50 percent and over on vaccination and they did a big push up front about how and where you can get vaccinated. Plus it is free for everyone. At this point, they assume everyone who wants to get a vaccine know where to get one or those who don't want one are just ignoring the push now.
I know someone who was getting like 3 calls a day asking if they are vaccinated or if they plan to get one. At this point, it doesn't seem to be a real ROI on calling people about it here.
