I wish I could get flu shots, but I'm allergic to them. It's not eggs or what they think of, it's the sulfite preservative and gelatin (which also contains sulfite). I get flu symptoms - all over pain, fever, fever ... used to think I really had the flu.
I was forced to have a pneumonia vaccination a couple of years ago when I was hospitalized. I was told there was no sulfite in it, but they lied. (I looked it up later.) I reacted and had to beg for a single Benadryl. They wouldn't give me more, when the symptoms came back, so I had my husband bring me some Alevert.
