This particular reply got me thinking... DS had a doctor he had seen in childhood before an insurance switch a few years back. Smaller clinic versus the "big" provider we're with now. So... we called them and asked. They said they were typically only doing vaccinations for infants but asked about the situation. Explained it to them and they said if we had paperwork they would be able to do them.
So... DS logged onto his portal and printed off a few forms, prescriptions, and instructions, and got a bunch of needle pokes this afternoon.
Thanks to Alliern, Mr. Mullen, and y'all here, this turned out to be a success story, so thank you!!! One problem solved, and now he awaits word on one more...
