Read the first 7 Contraindications & Precautions flashcards as text

  1. A nurse is preparing to administer the intranasal live attenuated influenza vaccine (LAIV4). Which patient condition is a contraindication specific to LAIV4?

    Answer: Concomitant aspirin therapy in children and adolescents

    LAIV4 is contraindicated in children and adolescents receiving aspirin or aspirin-containing products due to the risk of Reye syndrome associated with wild-type influenza.

  2. Which neomycin reaction type is a true contraindication to vaccines containing neomycin (e.g., MMR, varicella)?

    Answer: Anaphylaxis (immediate hypersensitivity)

    Anaphylaxis (immediate-type hypersensitivity) to neomycin is a contraindication; contact dermatitis, a delayed reaction, is not.

  3. A patient with a documented severe allergy to gelatin asks about varicella vaccination. Gelatin is a stabilizer in many vaccines including varicella. What is the correct classification of gelatin anaphylaxis in this context?

    Answer: Contraindication; gelatin anaphylaxis contraindicates varicella and other gelatin-containing vaccines

    Anaphylaxis to gelatin is a contraindication to gelatin-containing vaccines such as varicella, MMR, and yellow fever because gelatin serves as a heat-stable protein stabilizer.

  4. Which scenario represents a situation where a vaccine was INCORRECTLY withheld based on an invalid contraindication?

    Answer: DTaP withheld from an infant whose sibling has a contraindication to DTaP

    A sibling's contraindication is NOT a valid reason to withhold vaccine from another child; only the patient's own medical history is relevant.

  5. A 60-year-old patient with a history of receiving a bone marrow transplant 8 months ago is being evaluated for revaccination. What is the recommended approach for live vaccines?

    Answer: Live vaccines should generally be deferred until at least 24 months post-transplant and only if the patient is not immunosuppressed

    ACIP recommends deferring live vaccines until at least 24 months after hematopoietic stem cell transplant, and only when the patient is immunocompetent and not on immunosuppressive therapy.

  6. A healthcare worker (HCW) has never had chickenpox and is not sure of her varicella immunity. She is currently taking low-dose methotrexate (7.5 mg/week) for rheumatoid arthritis. What is the correct guidance for varicella vaccination?

    Answer: Methotrexate is a precaution; consult with her rheumatologist before administering live vaccine

    Low-dose methotrexate is considered a precaution rather than a contraindication for live vaccines; clinical judgment in consultation with the treating physician is required.

  7. Under the National Childhood Vaccine Injury Act (NCVIA), which action is required before administering vaccines listed on the Vaccine Injury Table?

    Answer: Provide the patient or guardian with the appropriate Vaccine Information Statement (VIS)

    Federal law (NCVIA) requires providers to give the appropriate CDC Vaccine Information Statement (VIS) before each dose of covered vaccines.
