Read the first 7 Contraindications & Precautions flashcards as text

  1. A 2-year-old with a history of intussusception at age 8 months presents for routine vaccination. Which vaccine carries a contraindication related to this history?

    Answer: Rotavirus vaccine

    Rotavirus vaccine is contraindicated in children with a history of intussusception due to the association between the condition and the vaccine.

  2. Which of the following correctly differentiates a contraindication from a precaution?

    Answer: A contraindication means the vaccine should generally never be given; a precaution means carefully weigh risks and benefits

    A contraindication indicates that a vaccine should not be administered, while a precaution signals a condition that might increase risk or reduce efficacy, requiring individualized clinical judgment.

  3. A 35-year-old pregnant woman is in her first trimester. Which vaccine is ABSOLUTELY contraindicated during pregnancy?

    Answer: Varicella vaccine

    Varicella vaccine is a live attenuated vaccine and is absolutely contraindicated during pregnancy due to potential fetal harm.

  4. A patient who received IVIG 3 months ago needs MMR vaccination. What should the provider do?

    Answer: Defer MMR based on the dose of IVIG received, following ACIP's recommended intervals

    The required interval after IVIG before giving MMR depends on the IVIG dose, ranging from 3 to 11 months per ACIP guidelines.

  5. Which of the following is NOT a valid contraindication to DTaP vaccination?

    Answer: Temperature of 40.5°C (105°F) within 48 hours of a prior DTaP dose

    Temperature of ≥40.5°C within 48 hours of a prior DTaP dose is classified as a precaution, not a contraindication, for subsequent doses.

  6. A patient with well-controlled HIV and a CD4 count of 350 cells/mm³ needs vaccination. Which statement about MMR is correct?

    Answer: MMR may be given to HIV-positive persons who are not severely immunocompromised (CD4 ≥200 cells/mm³)

    ACIP recommends MMR for HIV-infected persons who are not severely immunocompromised, defined as CD4 count ≥200 cells/mm³ in adults.

  7. Which of the following is an example of an INVALID contraindication often cited incorrectly?

    Answer: Current mild illness without fever

    Mild illness without fever is NOT a valid contraindication; vaccines may be safely administered to persons with minor illnesses.
