I eat eggs and chicken all the time with no problem that I know of so I wouldn't think that I would have a sensitivity to either. My skin reaction to the flu shot was very pink, warm, it was a few inches in diameter, and lasted for several days (or maybe longer, I can't remember). I talked to a person who gave the shot and she said it looked like a skin reaction and wasn't too worried about it. There were no hives. Benadryl made it better. My skin is very sensitive to everything nowadays. Perhaps the Supartz would be fine... I'm just not sure it is worth the risk or money. I'm tired of being injured.
