A practical nurse is collecting data from the parent of a 15-month-old toddler during a routine well-child visit. The clinic protocol indicates the toddler is scheduled to receive the live-attenuated varicella vaccine. Which statement by the parent requires the nurse to withhold the immunization and immediately consult the healthcare provider?
- AMy child is currently pulling up to stand on the furniture but has not taken an independent step yet.
- BMy child had a localized red, swollen area on their thigh for two days after their last set of vaccines.
- My child received a transfusion of packed red blood cells three months ago following a surgical procedure.Answer
- DOur family adheres to a strict cultural plant-based diet, so my child has never consumed dairy products.
Answer
The correct statement is the one reporting that the child received a transfusion of packed red blood cells three months ago.
The varicella vaccine is a live-attenuated immunization. Administering a live vaccine within several months of receiving an antibody-containing blood product (such as packed red blood cells) is contraindicated. The passive antibodies present in the transfused blood can interfere with the toddler's ability to mount an active immune response to the live vaccine virus, rendering the immunization ineffective. The nurse must withhold the vaccine and consult the provider to determine the correct waiting interval before administration.
