She didn't come out and say they are "her concerns", but I think she has concerns about the long-term impacts, because the vaccine has only been out a few months and it's a "new vaccine". I have told her that this vaccine works similar to the flu vaccine, but she doesn't get that vaccine each year either. She's not an "anti-vaxxer", and I think she will end up getting the vaccine, but she just has some general long-term concerns. It was one of those things that it wasn't worth getting into an argument last night, but it will turn into a more substantial argument if she resists getting the vaccine. I think she just has some general fatigue about the pandemic and all of the strong opinions on both sides.
