A nurse is preparing to administer immunizations to a child who has an allergy to eggs. The nurse should know that an allergy to eggs is a contraindication for which of the following immunizations?

Choice A rationale The Haemophilus influenza type b (Hib) vaccine is not contraindicated for people with egg allergies. The Hib vaccine is used to prevent Haemophilus influenza type b, a bacteria responsible for severe pneumonia, meningitis and other invasive diseases almost exclusively in children aged less than 5 years19. Choice B rationale The Inactivated poliovirus (IPv) vaccine is not contraindicated for people with egg allergies. The IPV vaccine is used to prevent polio, a crippling and potentially deadly infectious disease19. Choice C rationale The Hepatitis B (HepB) vaccine is not contraindicated for people with egg allergies. The HepB vaccine is used to prevent hepatitis B, a viral infection that attacks the liver19. Choice D rationale The Influenza vaccine is contraindicated for people with severe egg allergies. Most flu vaccines today are produced using an egg-based manufacturing process and thus contain a small amount of egg protein called ovalbumin19.
