SECTION 1: ADULT IMMUNIZATION SCHEDULES & GENERAL
PRINCIPLES
1. A 68-year-old male with a history of COPD and coronary artery disease
presents for an annual physical. He has no documented history of receiving
the Pneumococcal vaccine. According to the latest 2026 ACIP guidelines,
which of the following regimens is recommended?
• A) PCV20 alone
• B) PCV15 followed by PPSV23 one year later
• C) PPSV23 alone
• D) PCV20 followed by PPSV23 six months later
Rationale: The 2026 guidelines recommend that adults aged 65 years or older who
have not previously received a pneumococcal conjugate vaccine or whose history
is unknown should receive either PCV20 alone or PCV15 followed by PPSV23.
PCV20 covers all 13 serotypes in PCV13 plus 7 additional serotypes found in
PPSV23, simplifying the schedule to one dose.
2. A 27-year-old pregnant patient (G2P1) is at 28 weeks gestation. She received
Tdap at 24 weeks during her first pregnancy two years ago. What is the
appropriate action regarding Tdap today?
, • A) Administer Tdap now to boost pertussis antibodies for the neonate
• B) Hold Tdap as it has been less than 5 years since her last dose
• C) Administer Td only to avoid the pertussis antigen during pregnancy
• D) Wait until the postpartum period to administer Tdap
Rationale: ACIP recommends Tdap during EVERY pregnancy, preferably
between 27 and 36 weeks of gestation, regardless of the interval since the prior
Tdap or Td vaccination. This optimizes passive antibody transfer to the newborn to
prevent neonatal pertussis.
3. A 52-year-old female with a history of breast cancer on active chemotherapy
presents for a flu shot. Which statement regarding influenza vaccination is
correct?
• A) The live attenuated influenza vaccine (LAIV) is preferred due to her
immunocompromised state.
• B) She should receive the high-dose inactivated influenza vaccine (Fluzone
High-Dose) as it is the only option for cancer patients.
• C) She should receive an inactivated or recombinant influenza vaccine; the
live vaccine is contraindicated.
• D) Vaccination is deferred until chemotherapy is completed due to lack of
efficacy.
Rationale: Patients who are immunocompromised due to chemotherapy should
receive inactivated or recombinant influenza vaccines. Live attenuated influenza
vaccine (LAIV, the nasal spray) is contraindicated in this population.
4. Which of the following is a contraindication to receiving the Measles,
Mumps, Rubella (MMR) vaccine?
• A) Egg allergy
• B) Mild acute illness with low-grade fever
• C) History of Guillain-Barré syndrome 6 weeks after a prior flu shot
• D) Receipt of immune globulin within the past 3 to 11 months
Rationale: Passive antibodies from blood products (immune globulin) can
interfere with the replication of live virus vaccines like MMR. The interval
,depends on the dose and indication for immune globulin. Egg allergy is not a
contraindication to MMR.
5. A 60-year-old patient presents for a shingles vaccine. He reports a history of
chickenpox as a child but does not recall ever having shingles. He asks if he
needs the vaccine. What is the NP’s best response?
• A) "Since you have natural immunity from chickenpox, you do not need the
shingles vaccine."
• B) "You should receive the live zoster vaccine (Zostavax) because you are
under 65."
• C) "The recombinant zoster vaccine (Shingrix) is recommended for adults
50 years and older regardless of prior chickenpox history."
• D) "We must perform a titer check for VZV antibodies before administering
the vaccine."
Rationale: Shingrix (recombinant zoster vaccine) is recommended for
immunocompetent adults aged ≥50 years. Prior episode of chickenpox or
shingles is not a requirement; efficacy is high in those with prior exposure.
Zostavax is no longer available in the US.
6. A 32-year-old healthcare worker has no evidence of immunity to Hepatitis B
(HBsAb negative). She received the first dose of the HepB vaccine one month
ago. What is the appropriate schedule for completing the series?
• A) Dose #2 now, Dose #3 in 4 months
• B) Dose #2 now, Dose #3 in 2 months
• C) Dose #2 in 1 month, Dose #3 in 5 months
• D) Dose #2 in 6 months, Dose #3 in 12 months
Rationale: The standard schedule for HepB vaccination in adults is 0, 1, and 6
months. She is due for Dose #2 now (1 month after Dose #1), followed by Dose
#3 at 6 months after Dose #1.
7. An 80-year-old patient reports a history of shingles five years ago. He asks if
he should still get the Shingrix vaccine. What should the NP do?
, • A) Recommend deferring the vaccine, as natural infection provides lifelong
immunity.
• B) Administer one dose of Shingrix now.
• C) Administer the two-dose series of Shingrix as recommended.
• D) Test for VZV IgG antibodies first to determine need.
Rationale: ACIP recommends that adults aged ≥50 years receive the two-dose
series of Shingrix regardless of a prior episode of herpes zoster.
8. Which vaccine is universally recommended for all adults aged 19 to 59
years?
• A) Pneumococcal (PCV20)
• B) Human Papillomavirus (HPV)
• C) Hepatitis B (HepB)
• D) Zoster recombinant (RZV)
Rationale: As of the 2026 schedule, Hepatitis B vaccination is recommended for
all adults aged 19-59 years, without requiring risk factor assessment.
SECTION 2: PEDIATRIC & ADOLESCENT IMMUNIZATIONS
9. A 12-month-old infant is due for routine vaccines. Which vaccine is
contraindicated if the child has a severe allergy to gelatin?
• A) DTaP
• B) MMR (Measles, Mumps, Rubella)
• C) Hepatitis A
• D) PCV13
Rationale: The MMR vaccine contains hydrolyzed gelatin as a stabilizer. Severe
allergic reaction (e.g., anaphylaxis) to gelatin is a contraindication to the MMR
vaccine.
