to almost anyone we have heard from. My husband got Pfizer and I got Moderna. We are both retired RNs. Mine was given by a hospital LPN, his by a National Guard person who he did not question their "other job". We both comment that they were excellent injections. When I get my second Wednesday, I may ask the gauge of the needle. He had his second last week. He did have a reaction (which we consider to be a good thing). He had chills and muscle aches during the night. But whenever he has had flu like illnesses, those muscle aches were expected.
