A nurse is preparing to administer the varicella vaccine to a group of clients. The nurse should identify which of the following clients as having a contraindication for receiving this immunization?

A. A child who recently received the human papillomavirus vaccine. This is not a contraindication for receiving the varicella vaccine. Vaccines can generally be administered simultaneously or at any interval between doses of different vaccines. B. A young adult who has an allergy to eggs. This is not a contraindication for the varicella vaccine. The varicella vaccine does not contain egg proteins, so an egg allergy does not prevent someone from receiving it. C. A client who has AIDS. This is a contraindication for the varicella vaccine. Individuals with severe immunocompromising conditions, such as AIDS, should not receive live vaccines like the varicella vaccine due to the risk of severe vaccine-related complications. D. An older adult client living in a long-term care facility. This is not a contraindication for the varicella vaccine. Older adults can receive the varicella vaccine unless they have specific contraindications such as severe immunocompromise.
