Hi Don, I guess that would depend. Someone going into chemo, I read two, three months before, during, and soon after, should not receive any immunizations due to possibly having a suppressed immune system. Is this followed, no. My first chemo in 2009 which was disastrous, I had the Flu, and pneumonia vaccine during my Induction Chemo, and what else they wanted to give me, and believe through research, symptoms, records, I may have suffered two rare conditions, amongst others, Gallium Barre Syndrome, and Steven Johnson Syndrome. Last year, the same day as chemo, I received a Flu vaccine, which I later only learned of the contradictions. This year I received the Flu vaccine in October, two months before chemo. I must say, although a different type treatment with Protons and Carboplatin, this was the easiest for me. Last year wasn't, and Erbitux is supposed to be easy, but I was laced with Taxotere too lol.

This far out from chemo, even radiation can suppress the immune system, blood work can see if your immune system is compromised. Mine is, but have other co-medical conditions, presecriptions, which I cross reference often now with any medications, treatments I'm going to receive.
