In the past I never got the flu vaccine, as I never get the flu (I mean never) even when everybody around me is getting it. However, 2 years ago my grandson was born a micropreemie and I could not be around him unless I got H1N1 and seasonal flu vaccine, which is why I started getting it. So, this is the third time that I have gotten flu vaccine. I do not plan to get it again. I have never had a reaction in the past. Perhaps another important piece of information is that I do have Hashimoto's Disease.
