Walgreens review: Covid vaccination

I had my first vaccine on Feb.23, 2021. I had the Moderna vaccine. Next one due on March 23 at Walgreens, Military Highway, Pineville, LA. I made my second appointment on Friday for my Tuesday second vaccination. So far so good. Went to Walgreens to double-check on my appointment. The girl I talked to told me, "We have no more COVID-19 doses". I asked why did they not save some for my second Dose. Then she asked me who gave me the first dose. I told her and she just walked away without even saying anything else. She did say a couple of times, "There is no more doses" Did not even have a chance to ask her when the next batch would be coming. My question is, They gave my first dose, so what happened for my second dose? I am 81 years old. So now I will have to start all over again? William Brown, Tel. Number: [protected]
