My sister the RN explained to me why people have more side effects after the second shot than the first. Apparently, the first shot starts the process of your body's immune system preparing to fight the virus. When you get the second shot, the body's immune system sees it as it would the virus, and the immune system and the vaccine kind of fight with each other a bit. However, in the end, the second shot makes the body's immune response to the virus stronger.
The biggest side effect reported by the hospital staff where my sister works was being VERY tired the day after the second shot. They all got the Pfizer or Moderna vaccines. Pfizer's vaccine is what I am getting, so I'm expecting to be tired after my second shot in two weeks.
