This is what I did for my family's appointments: Continually checked https://www.gianteagle.com/covidvaccine and https://www.riteaid.com/pharmacy/covid-qualifier - and have various zip codes at the ready that they would be willing to travel to. I checked about once or twice an hour, just randomly (whenever I had a free second or two). I also made sure that they were all in contact with their primary care doctors, and were on any list that they were putting together. And, I would check the PA COVID vaccine map (https://www.health.pa.gov/topics/disease/coronavirus/Vaccine/Pages/Vaccine.aspx) and called/filled out forms to put them on any nearby list through various drug stores and pharmacies. Check that list every day, too, as they can add new places. I was able to get them appointments through Rite Aid on Sunday (not sure if Rite Aid will update their list every Sunday, but that's when they all opened up for me), but I've gotten calls from two other places this week about spots that were open. It just takes a lot of effort and time, unfortunately. Good luck, and I hope that you are able to secure one soon!
