This morning, one of my friends told me that she will take a vaccine against influenza this year. Since she had avoided taking it because of her egg allergy, she finally caught flu and had a quite high fever last year. I had never thought about what the vaccines for flu were made of. It seemed that egg shells were used to make the vaccines. Her family doctor told her that she had allergies for yolk and the white, not the shells. I wonder why her family doctor didn’t tell her about it earlier. She didn’t have to suffer from flu symptoms last year.
