Christine, as far as Medicare, I don't think it will vary state to state, being it's Federal, but good question.

I received the flu vaccine when hospitalized for surgery in October, and read previously you should not receive any vaccines a month before, during, shortly after chemo treatment due to possibly effecting the immune system, and having adverse reactions. I didn't know this in 2009, and was given the flu, and pneumonia vaccine during treatment, and had adverse effects. Last year, it was just the flu shot during chemo. I guess all chemo's are different, and everyone should check with their doctor, if not sure. With Carboplatin it says the same, no vaccines.
