the mother of a 2-year-old child asks the nurse administering influenza vaccine at a community health fair if a person can actually contract the flu from the vaccine itself. the mother is concerned because she cares for other children in her home and wants to protect herself and her toddler. the mother states that she herself has no known allergies but says the child is allergic to peanuts, eggs, and dairy products. how should the nurse respond? should the nurse administer the vaccine to the mother and child?
