Question

My wife has had a letter from the doctor about a flu jab. But it also - that if she has an egg allergy, she's not to attend. Why?

Answer

This is because the flu vaccine is grown in eggs, so there will be a smidgen of contaminating egg in the final vaccine. If she's allergic, she might get a reaction so it's best not to go along.
