Hi, and I understand your concern about additives. I think they have corrected any problems with this. Unless you are alergic to eggs, I don't think it would be a problem. I do have a compromised immune system, so even more important for me. I would get 10 shots and risk most any symptom, rather than to get that flu again. It was type A asian flu, gotten on a cruise, which is a floating petri dish. Yes close quarters with lots of other people can be a danger. That is why most all health care professionals get their shot. More risk from the flu for sure, than the shot, especially if you tend to get sick easily. Also cold winters, where people are confined, carries more risk. I hope you ask your PCP, and do bring your concerns about the additives to his or her attention. wish you the best, NO flu. ginnie
