1Which of the following diseases is caused by a vaccine-preventable virus for which no live attenuated vaccine is currently recommended in the United States?

A.Hepatitis B

B.Measles

C.Varicella

D.Yellow fever

Explanation: Hepatitis B vaccine is a recombinant subunit vaccine containing hepatitis B surface antigen (HBsAg) produced in yeast. It is not a live vaccine. Measles (MMR), varicella (Varivax), and yellow fever (YF-Vax) are all live attenuated vaccines that are contraindicated in severely immunocompromised patients and pregnancy.

2A patient asks what 'herd immunity' means. What is the best technician response?

A.Indirect protection of unvaccinated individuals when a high percentage of the population is immune

B.Lifelong protection conferred by a single vaccine dose

C.Immunity that only develops after natural infection

D.The ability of a vaccine to prevent all disease symptoms

Explanation: Herd immunity (community immunity) occurs when enough people in a population are immune to an infectious disease — through vaccination or prior infection — that it becomes difficult for the disease to spread. This indirectly protects those who cannot be vaccinated, such as infants under 6 months and immunocompromised patients. Thresholds vary by pathogen (measles requires ~95% coverage).

3Which of the following best describes the difference between active and passive immunity?

A.Active immunity involves the body producing its own antibodies; passive immunity provides preformed antibodies

B.Active immunity is short-lived; passive immunity is permanent

C.Active immunity comes from immunoglobulin injections; passive immunity comes from vaccines

D.There is no clinical difference between the two

Explanation: Active immunity develops when the immune system produces its own antibodies in response to a pathogen or vaccine, providing long-lasting protection. Passive immunity provides immediate but temporary protection via preformed antibodies, such as maternal antibodies, immunoglobulin (IG), or monoclonal antibodies like nirsevimab for RSV prophylaxis in infants.

4Per the 2025-2026 CDC ACIP adult immunization schedule, which vaccine is recommended as a one-time dose for all adults aged 75 years and older?

A.RSV vaccine

B.Annual tetanus booster

C.Yellow fever vaccine

D.Hepatitis A vaccine

Explanation: ACIP recommends a single dose of RSV vaccine (Arexvy, Abrysvo, or mResvia) for all adults aged 75 years and older, and for adults aged 50-74 years at increased risk for severe RSV disease. RSV vaccine is given once — it is not currently an annual vaccine. Tdap (not tetanus alone) is given every 10 years.

5Which of the following vaccines is classified as a live attenuated vaccine?

A.MMR (measles, mumps, rubella)

B.Tdap

C.Hepatitis B

D.Inactivated influenza (IIV)

Explanation: MMR is a live attenuated vaccine and is contraindicated in pregnancy and severe immunocompromise. Tdap is a toxoid/acellular vaccine, hepatitis B is a recombinant subunit vaccine, and inactivated influenza (IIV) is killed virus. Other live vaccines include varicella, MMRV, LAIV (FluMist), yellow fever, oral typhoid, and zoster live (no longer recommended — replaced by Shingrix).

6A 65-year-old patient with no prior pneumococcal vaccination asks about pneumococcal protection. Per current ACIP recommendations, which single-dose regimen is appropriate?

A.1 dose of PCV20 or PCV21

B.1 dose of PPSV23 only

C.2 doses of PCV13 separated by 8 weeks

D.PCV7 followed by PPSV23

Explanation: Current ACIP recommendations for pneumococcal vaccine-naive adults 50 years and older include a single dose of PCV15, PCV20, or PCV21. If PCV15 is used, it should be followed by PPSV23 at least one year later. PCV20 and PCV21 do not require a PPSV23 follow-up. PCV7 and PCV13 are no longer routinely recommended for this population.

7Which of the following vaccines protects against human papillomavirus (HPV)?

A.Gardasil 9

B.Shingrix

C.Twinrix

D.Bexsero

Explanation: Gardasil 9 is a 9-valent recombinant HPV vaccine that protects against HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. It is routinely recommended starting at ages 9-12 and can be given through age 26, with shared clinical decision making up to age 45. Shingrix is for zoster, Twinrix is hepatitis A + B, and Bexsero is meningococcal B.

8Shingrix (recombinant zoster vaccine) is recommended for which population per ACIP?

A.Adults aged 50 years and older, and immunocompromised adults aged 19 years and older

B.Only adults aged 60 years and older

C.All children at age 12

D.Only patients with a history of chickenpox

Explanation: Shingrix is recommended as a 2-dose series (0, 2-6 months) for immunocompetent adults aged 50 years and older and for immunocompromised adults aged 19 years and older. It is a non-live recombinant subunit vaccine, so it is safe in immunocompromised patients — unlike the older Zostavax live vaccine, which was discontinued in the U.S. in 2020.

9What does EUA stand for in the context of vaccine regulation?

A.Emergency Use Authorization

B.Expanded Use Approval

C.European Union Authorization

D.Essential Usage Allowance

Explanation: An Emergency Use Authorization (EUA) is a mechanism by which the FDA can permit use of unapproved medical products, or unapproved uses of approved products, during declared public health emergencies. Several COVID-19 vaccines were initially distributed under EUA before receiving full Biologics License Application (BLA) approval.

10Which of the following is an example of an mRNA vaccine?

A.Pfizer-BioNTech COVID-19 vaccine (Comirnaty)

B.Shingrix

C.Gardasil 9

D.Hepatitis B vaccine

Explanation: Comirnaty (Pfizer-BioNTech) and Spikevax (Moderna) are mRNA vaccines that deliver messenger RNA encoding the SARS-CoV-2 spike protein. The body's cells translate this mRNA to produce the spike protein, which triggers an immune response. Shingrix and Gardasil 9 are recombinant subunit vaccines; hepatitis B is also a recombinant subunit vaccine.

PTCB Immunization Study Tips from Top Performers

1Memorize the 2025-2026 CDC ACIP adult and child schedules - influenza, COVID-19, RSV, Tdap, MMR, HPV, zoster (Shingrix), and pneumococcal (PCV15/PCV20/PCV21/PPSV23) are the highest-yield vaccines

2Master needle selection: 22-25G x 1 to 1.5 inch for adult IM deltoid; 23-25G x 5/8 inch for SC in triceps; always 90 degree for IM, 45 degree for SC

3Know contraindications vs precautions cold - severe allergic reaction to a prior dose or component is an absolute contraindication; moderate/severe acute illness is a precaution

4Drill the anaphylaxis protocol: epinephrine 0.3 mg IM 1:1000 in the vastus lateralis, repeat every 5-15 min, call 911, supine position

5Understand VFC cold-chain specifics: 2-8 C refrigerator, -50 to -15 C freezer for varicella/MMRV/zoster live, digital data logger with buffered probe

6Memorize the 15-minute post-vaccination observation period for syncope (30 minutes if prior allergic reaction) and how to manage vasovagal reactions

Frequently Asked Questions

What is the passing score on the PTCB Immunization Administration exam?

You need a scaled score of 300 out of a possible 0-400. The exam contains 60 multiple-choice questions delivered by Pearson VUE (in-center or online proctored). PTCB does not publish a fixed percentage correct required to pass because the exam uses scaled scoring that adjusts for form difficulty.

How much does the PTCB Immunization Administration Certificate cost?

The PTCB exam fee is $89. You must also complete a PTCB-Recognized Immunization Administration Training Program separately, which typically costs $150-$350 depending on the provider (ASHP, ACPE-accredited programs, state pharmacy associations). Total out-of-pocket cost is usually $250-$450.

Who is eligible to take the PTCB Immunization Administration exam?

You must hold an active PTCB CPhT (Certified Pharmacy Technician) credential AND complete a PTCB-Recognized Immunization Administration Training Program. State law must also permit pharmacy technicians to administer vaccines under pharmacist supervision - check your state board of pharmacy before enrolling.

Can pharmacy technicians administer vaccines in every state?

No. As of 2026, more than 35 states explicitly allow properly trained pharmacy technicians to administer vaccines under direct pharmacist supervision, but rules vary widely. Some states require specific CE hours, age limits for patients, or restrict which vaccines technicians may give. Always verify your state board of pharmacy regulations before administering.

What is the format of the PTCB Immunization exam?

60 multiple-choice questions (4 options each) delivered via Pearson VUE. Total appointment is 1 hour 30 minutes: 5-minute tutorial, 1 hour 20 minutes of test time, and 5-minute post-exam survey. Three knowledge domains: Concepts and Terminology (30%), Vaccine Safety and Administration (50%), and Documentation/Product Handling/Adverse Reactions (20%).

What is the correct needle gauge and length for IM vaccination of adults in the deltoid?

Per CDC recommendations: 22-25 gauge, 1 to 1.5 inch needle for most adults. Use a 5/8 inch needle only if the skin is stretched flat and injection is at a 90 degree angle (some COVID-19 and flu manufacturers). Use 1 inch for adults under 130 lbs (60 kg) and 1.5 inch for adults over 200 lbs (women) or 260 lbs (men).

How is anaphylaxis treated at a pharmacy vaccination site?

Administer epinephrine 0.3 mg (0.3 mL of 1:1000 aqueous solution) IM in the mid-outer thigh (vastus lateralis) immediately. Call 911. Place patient supine with legs elevated (unless vomiting or difficulty breathing). Dose may be repeated every 5-15 minutes if symptoms persist. All vaccination sites must stock epinephrine and have an anaphylaxis emergency protocol.

What are the VFC cold chain temperature requirements?

Refrigerated vaccines: 2 to 8 degrees Celsius (36 to 46 F). Frozen vaccines (varicella, MMRV, zoster live): -50 to -15 C (-58 to +5 F). Temperatures must be recorded at least twice daily with a calibrated digital data logger. Diluents are stored with the vaccine or at room temperature - never frozen. Out-of-range events require immediate protective action and reporting to the state VFC coordinator.
