<<Disclaimer: Verify this information before applying it to your situation.>> Earlier I posted a question about flu shots. Specifically, one of the things I read on the label said "hemagglutinin". This is actually an adj and not a noun as it describes the noun antibody. The label said fully "hemagglutinin antibody". It means the antibody is of a type to cause the blood to clump together. I found this definition on the web in the Webster's dictionary. Apparently the glutinin part of the adj refers more to the effect the antibody has on the blood (causes bonding) rather than the "bad" protein that celiacs fear and dread. Again this is still only an opinion and not medical fact. Other than the definition of hemagglutinin, I have no supporting fact as of yet. Cheers, Richard Rushton [log in to unmask]
