Just be aware that all flu shots do still contain mercury. Be sure to weigh that into your decisions. I know, so much to remember and think about . . . even if you DON'T have a kid with DMD.Thank you all so much for the information. We will definitely wait 4 weeks before starting the deflazacort. And, I will make sure he gets his flu shots.
Like Lee Ann said, you can test for titers before giving any boosters (MMR, Chickenpox). I would do that anyway before giving a booster shot - why give you kids additional vaccinations if their bodies are already making sufficient antibodies?
