I received a robo call tonight telling me it was time for my booster shot. I got the J&J jab towards the end of September! I only got it because I was forced to get it or I wouldn’t be able to work in DC because they are stupid. This robo call knew when, where, and what kind of jab I got. Here is the number. +1 (240) 673-2163. It’s the Maryland GoBack Covid-19 support center.
