A child is receiving long-term systemic corticosteroids (2 mg/kg/day prednisone for >14 days). Which vaccine should be deferred until at least 1 month after therapy ends?
Answer: MMR vaccine
Live vaccines like MMR are contraindicated in persons receiving high-dose systemic corticosteroids for ≥14 days; defer until at least 1 month after cessation.
Which of the following is a TRUE contraindication to receiving the yellow fever vaccine?
Answer: Thymus disorder associated with abnormal immune function
Thymus disorder associated with abnormal immune function is a contraindication to yellow fever vaccine due to risk of vaccine-associated viscerotropic disease.
An adolescent received a tetanus-containing vaccine 3 years ago. She now presents for a Tdap booster. Is her recent vaccination history a contraindication?
Answer: No, 3 years is an adequate interval and she may receive Tdap
ACIP recommends a minimum 2-year interval between tetanus-containing vaccines, so 3 years is acceptable for Tdap administration.
A 70-year-old patient reports a previous episode of Guillain-Barré syndrome (GBS) 6 weeks after receiving influenza vaccine. What is the appropriate action?
Answer: GBS within 6 weeks of prior influenza vaccine is a precaution; weigh risks and benefits
GBS within 6 weeks of a prior influenza vaccine is classified as a precaution, not a contraindication; clinicians should weigh individual risk versus benefit.
Which condition is considered a PRECAUTION (not a contraindication) for the varicella vaccine?
Answer: Recent receipt of antibody-containing blood product
Recent receipt of antibody-containing blood products is a precaution for varicella vaccine because passively acquired antibodies may interfere with the immune response.
A breastfeeding mother asks about receiving the live attenuated influenza vaccine (LAIV). Which statement is correct?
Answer: LAIV is not recommended in breastfeeding women but is not contraindicated
LAIV is not recommended for breastfeeding women due to theoretical risk, but it is not classified as a contraindication; inactivated influenza vaccine is preferred.
A patient has a latex allergy causing urticaria after latex glove contact. Which action is most appropriate when administering a vaccine packaged with a latex-containing vial stopper?
Answer: Administer with caution; latex urticaria allergy is a precaution, not a contraindication
Contact urticaria from latex is a precaution; only anaphylactic reaction to latex contraindicates use of vaccines in latex-containing packaging.
