  1. Which catch-up vaccination strategy applies to an unvaccinated 15-year-old with no prior immunization history?

    Answer: Follow the catch-up immunization schedule for persons 7 through 18 years

    Unvaccinated or incompletely vaccinated persons aged 7–18 years should follow the ACIP catch-up immunization schedule designed for that age group.

  2. Renal dialysis patients are recommended to receive higher-dose hepatitis B vaccines. Which formulation is specifically indicated for this population?

    Answer: Recombivax HB 40 mcg (dialysis formulation)

    Recombivax HB 40 mcg (dialysis formulation) is specifically indicated for predialysis and dialysis adult patients, as this population has a diminished immune response to standard doses.

  3. Yellow fever vaccine is a live attenuated vaccine and is generally contraindicated in which group of travelers?

    Answer: Pregnant women and severely immunocompromised persons

    Yellow fever vaccine is contraindicated in pregnant women and severely immunocompromised persons due to the risk of vaccine-associated viscerotropic or neurotropic disease.

  4. In homeless shelter populations, which vaccine is particularly important to administer during outbreaks due to documented increased risk in congregate settings?

    Answer: Hepatitis A vaccine

    Hepatitis A outbreaks have been frequently documented in homeless and unhoused populations in the US, making hepatitis A vaccination a priority in these congregate settings.

  5. For adults aged 50 years and older, which shingles vaccine is currently preferred over the previous Zostavax (ZVL) formulation?

    Answer: Shingrix (RZV – recombinant zoster vaccine)

    Shingrix (RZV) is the preferred herpes zoster vaccine for adults 50+ due to its superior efficacy (>90%) compared to the older live Zostavax, which has been discontinued in the US.

  6. Which population is considered high-risk for severe varicella and should receive varicella vaccination or serologic confirmation of immunity before potential exposure?

    Answer: Healthcare workers without evidence of varicella immunity

    Healthcare workers without evidence of varicella immunity are at high risk for exposure and should receive varicella vaccine or serologic confirmation of immunity due to occupational risk.
