Read the first 7 Contraindications & Precautions flashcards as text

  1. A patient experienced an Arthus-type reaction after a tetanus toxoid dose 2 years ago. What is the recommended interval before the next tetanus-containing vaccine?

    Answer: At least 10 years

    An Arthus reaction (a type III hypersensitivity) following a tetanus-containing vaccine is a precaution, and ACIP recommends waiting at least 10 years before the next tetanus-containing vaccine.

  2. Herpes zoster recombinant subunit vaccine (RZV, Shingrix) is preferred over zoster live vaccine (ZVL, Zostavax). Which condition is a contraindication to RZV?

    Answer: Anaphylaxis to a previous RZV dose or any of its components

    Anaphylactic reaction to a prior dose of RZV or to any of its components (including AS01B adjuvant) is the primary contraindication to Shingrix.

  3. A child presents with a family history of seizures. Is this a contraindication to MMR vaccination?

    Answer: No, family history of seizures is not a contraindication; it may be a precaution in some scenarios

    Family history of seizures is not a contraindication to MMR; it may prompt discussion about febrile seizure risk, but vaccination should proceed.

  4. Which vaccine is contraindicated in an infant born to an HIV-positive mother whose HIV infection status has not yet been confirmed?

    Answer: BCG (Bacillus Calmette-Guérin)

    BCG, a live vaccine used to prevent TB, is contraindicated in infants with known or suspected HIV due to risk of disseminated BCG disease.

  5. A patient with an egg allergy reports hives after egg ingestion. Which influenza vaccine approach is recommended?

    Answer: Administer any licensed influenza vaccine; egg allergy of any severity is no longer a contraindication

    ACIP updated guidance states that influenza vaccine may be administered to all persons regardless of egg allergy severity, without special precautions beyond routine vaccination practice.

  6. Which of the following is a precaution for the administration of Tdap to a pregnant woman?

    Answer: History of Arthus-type reaction to a tetanus-containing vaccine within 10 years

    A history of an Arthus-type reaction to a tetanus-containing vaccine within the preceding 10 years is a precaution, even in pregnant women who otherwise should receive Tdap.

  7. A 4-month-old infant is scheduled for routine vaccines but is currently hospitalized with moderate-to-severe illness and a temperature of 39.5°C. What is the correct course of action?

    Answer: Defer all vaccines until the infant has recovered, as moderate-to-severe illness is a precaution

    Moderate-to-severe acute illness with or without fever is a precaution for all vaccines; vaccination should be deferred until the child recovers to avoid masking symptoms or complicating recovery.
