Immunizations
Which of the following could interfere with the effectiveness of a dose of Varivax? (Select ALL that apply.)
A. Acyclovir C. Valtrex D. MMR given 2 weeks prior to Varivax Systemic antivirals with activity against the herpes virus can inactivate the vaccine strain and should not be used within 24 hours before or 14 days after giving the vaccine. Famciclovir (Famvir) would be problematic as well. If not administered simultaneously, live vaccines should be separated by 28 days (4 weeks) to avoid antibody interference. Denavir (penciclovir) is a topical medication and for this reason, is unlikely to interfere.
A 67-year-old patient at your pharmacy has diabetes and heart disease. Which of the following vaccines is the patient eligible to receive today?
A. Prevnar 20 One dose of Prevnar 20 (or Vaxneuvance in series with Pneumovax 23) is recommended for all patients ≥ 65 years of age.
Which of the following statements concerning intramuscular injection is correct?
B. The injection site is above the level of the armpit and below the acromion process. Administration of vaccines at the proper anatomical site via approved routes is important to vaccine efficacy. Subcutaneous injections are given using a 5/8-inch needle, whereas intramuscular injections are given using a 1-inch needle in most adults. A 5/8-inch needle is used in IM injections if the patient is less than 130 pounds.
A 64-year-old female is in the pharmacy on September 10 to pick up her meloxicam prescription. The pharmacist notices that she is congested, with sneezing and she mentions a sore throat. Upon questioning, she states that she has not received her influenza vaccine yet this season. Which of the following is correct?
C. She can receive the influenza vaccine today since mild acute illness is not a contraindication. Vaccination should be deferred if the patient has a moderate or severe illness but can be administered to patients with mild acute illness (e.g., slight fever, mild diarrhea). If a patient is well enough to walk into the pharmacy, they are likely a candidate for vaccination. The CDC recommends giving the influenza vaccine as soon as it is available rather than deferring it until later in the season.
PR is a 45-year-old male who presents to the pharmacy on November 3rd to pick up a prescription. He has a history of asthma, hypertension, anxiety and intermittent depressive episodes. He was involved in a motor vehicle accident the previous summer, which resulted in a punctured lung, two fractured ribs and a lacerated spleen with subsequent splenectomy. He reports that he has not received any vaccines since he was an infant. Which of the following best represents the list of vaccines that are indicated for PR today?
E. Prevnar 20, Menveo, Hiberix, and Fluzone Due to PR's asplenia, he needs to receive H. influenza type b (Hiberix), meningococcal (Menveo) and pneumococcal (Prevnar 20) vaccines. Annual influenza vaccines are recommended for everyone six months and older during influenza season. Fluad and Fluzone High-Dose are indicated for use in patients ≥ 65 years old.
A pharmacist is working in a hospital that requires hepatitis B vaccination. She received the first dose of a 3-dose series. She did not return for the second dose, which was due one month later. It is now four months after the first dose. Select the correct recommendation:
E. She should get the second dose now and return for the third dose at the proper time. Increasing the interval between doses of vaccine given in a series does not diminish the effectiveness of the vaccine after completion of the series, but it may delay complete protection.
HS is a healthy 67-year-old female who presents to her PCP in October. Which vaccine should the pharmacist recommend for HS today?
E. Shingrix The high-dose influenza vaccine (e.g., Fluzone High Dose) produces a more robust immune response than FluMist and may better protect against influenza in adults ≥ 65 years of age. Prevnar 13 is no longer part of a recommended pneumococcal vaccine series in otherwise healthy adults 65 years and older.
Significant adverse reactions that occur after administration of a vaccine should be reported to the following:
E. VAERS Adverse reactions to vaccinations should be reported to the patient's primary care provider and the FDA's Vaccine and Adverse Event Reporting System (VAERS).
Choose the correct statements regarding SC administration of vaccines. (Select ALL that apply.)
A. Varivax, yellow fever and MMR are administered subcutaneously B. SC injections are administered into the fatty tissue over the triceps. D. SC injections are administered at a 45-degree angle. E. SC injections are administered using a needle that is 5/8 inch long. The upper outer arm (the fatty tissue over the triceps) is the preferred site for a SC vaccine injection in adults. SC injections should be administered at a 45-degree angle with a 5/8 inch needle. The shorter needle and angle of administration prevent accidental injection into the muscle.

A 20-year-old female has no evidence of immunity to varicella and is being vaccinated to prevent chickenpox. Which screening question must be asked before administering Varivax?
E. Have you ever had a severe reaction to gelatin? Varivax vaccines should not be administered to anyone with a true allergy to neomycin or gelatin (components of the vaccine). Varivax is a live vaccine and cannot be administered to severely immunocompromised patients. The steroid dose indicated here is not high enough to cause immunosuppression.
What does the "a" in DTaP stand for?
A. Acellular The "a" in DTaP and Tdap stands for acellular, meaning that the pertussis component contains only a part of the pertussis organism. Upper-case letters in these abbreviations denote full-strength doses of diphtheria (D) and tetanus (T) toxoids and pertussis (P) in the vaccine. Lower-case "d" and "p" denote reduced doses of diphtheria and pertussis used in the adolescent/adult formulations.

Select the correct statement concerning active and passive immunity.
B. The MMR vaccine provides active immunity. Active immunity is produced by a person's own immune system and is usually permanent. Active immunity (antibody production) occurs when a person becomes infected with the organism and recovers or receives a vaccination. Passive immunity is acquired when antibodies are provided by someone else. The most common forms of passive immunity include a pregnant mother sharing antibodies with her baby shortly before birth and through breast milk during breastfeeding. Antibodies contained in intravenous immunoglobulins are an example of passive immunity.
The manager at a pharmacy ordered 100 single-dose vials of Afluria. He found them stored in the pharmacy's freezer. Choose the correct course of action:

Fluad could be recommended for which of the following patients?
C. A 67-year-old female with a history of hyperthyroidism Fluad, a trivalent flu vaccine approved for patients ≥ 65 years old, contains an adjuvant to improve the antibody response. It is not an egg-free formulation. A severe reaction following a dose of vaccine is a contraindication to any subsequent dose of that vaccine. A patient who experiences Guillain-Barre within six weeks of a prior influenza vaccine should be referred to their healthcare provider.
Which vaccine can cause a false-positive reaction to the Tuberculin Skin Test (TST)?
C. Bacille Calmette-Guerin (BCG) Previous vaccination with Bacille Calmette-Guerin (BCG) can cause a false-positive reaction to a TB skin test. Though not often used in the United States, BCG is given to infants and small children in countries with a higher TB incidence.
Which of the following, if taken, would qualify as steroid-induced immunosuppression? (Select ALL that apply.)
C. Dexamethasone 4mg PO daily for three weeks. D. Prednisone 30mg PO daily for 22 days in an 11.8kg child To consider a patient immunocompromised due to steroid use, systemic steroids must be taken for at least 14 days at a dose of at least 20 mg or 2 mg/kg of prednisone daily (or equivalent). Steroids taken by inhaled, topical and intraarticular routes are not considered to be immunosuppressive.

Patients between the ages of six months and eight years, who have not been previously vaccinated for influenza, should receive two doses spaced four weeks apart. Patients with egg allergies can receive any age-appropriate inactivated influenza vaccine, even with severe reactions. FluMist should not be administered in patients with egg allergies. No additional observation period is recommended beyond the required 15 minutes.
Which of the following statements about the Shingrix vaccine is correct?
C. It should be administered even if the patient has a history of shingles. Shingrix is a recombinant (non-live vaccine) administered to prevent shingles outbreaks caused by the herpes zoster virus, even in patients with a history of shingles. It is administered IM into the deltoid muscle.
A 12-month-old child was hospitalized two months ago and received immune globulin for Kawasaki disease. Which vaccine/s would be adversely affected by this treatment if administered today? (Select ALL that apply.)
C. Measles, mumps, and rubella vaccine E. Varicella vaccine Antibodies, found in some blood products and intravenous immunoglobulins (IVIG), can interfere with live vaccine replication.
A 14-month-old child was hospitalized two months ago for a dog bite injury. She was not on schedule with her tetanus vaccine series, so tetanus immune globulin was given. Which vaccine would be affected by this treatment?
C. Measles-mumps-rubella-varicella (MMRV) MMR and varicella-containing vaccines are live vaccines that require replication to produce an immune response. If antibody-containing products (e.g., immunoglobulins) have recently been administered, live vaccines should not be given for at least three months (the recommended separation time varies depending on the product received). If an MMR or varicella-containing vaccine has recently been given, antibody-containing products should be avoided for at least two weeks after vaccination to prevent interference with vaccine efficacy.
PJ is a 13-month-old male who presents to the pediatrician for a routine check-up. He has never received an influenza vaccine. Which of the following is required?
C. One dose today, followed by a second dose in 28 days Children ages six months to eight years who are receiving an influenza vaccine for the first time require two doses, separated by four weeks.
JK is a 21-year-old male who presents to the urgent care clinic on June 22 with a puncture wound in his left foot after stepping on a nail when he walked outside barefoot. He remembers getting a tetanus shot at age 14 (it made his arm very sore) but has only gotten a flu shot every year since then. Which of these vaccines would be an appropriate selection to administer at this time? (Select ALL that apply.
C. Td D. Boostrix He has a dirty wound, and his last tetanus vaccine was > 5 years ago, so he should receive a tetanus booster with either Td or Tdap (Adacel or Boostrix). DT and DTaP are used in children age < 7 years. The uppercase D and P correlate to the higher antigen content of the childhood vaccines. The adult boosters contain less diphtheria and pertussis antigen because the immune system is already primed.
A community pharmacist who runs a vaccination clinic has run out of Vaccine Information Statements (VISs) for one of the vaccines being administered today. The pharmacist can use which of the following websites to obtain a copy of the VIS to provide to patients? (Select ALL that apply.)
C. The Immunization Action Coalition D. The Centers for Disease Control and Prevention (CDC) The CDC prepares Vaccine Information Statements (VISs) for each vaccine to explain the benefits and risks. Federal law requires that the VIS be handed to the patient before the vaccination is given. VISs can be found on the CDC and Immunization Action Coalition websites.
MP is a 29-year-old female who recently finished nursing school and is ready to start her new job. Her employer requires that she complete a tuberculosis screening. The TST was placed on Monday and read as negative by the Employee Health nurse on Wednesday. MP tells the nurse that she received the varicella vaccine last week since she did not have chickenpox as a child and is required to have documented immunity to varicella. What information should the Employee Health nurse communicate to MP?
C. The TST will have to be repeated four weeks after the Varivax; live vaccines can cause false-negative results. Live vaccines (e.g., varicella, MMR, ProQuad or FluMist) can be given on the same day as the TST or after the TST results are obtained (48-72 hours). If given before the TST, a false-negative result can occur, leading to untreated tuberculosis. It is recommended to wait four weeks after a live vaccine to administer the TST.
A small community pharmacy just received a delivery of influenza vaccines. The pharmacy owner needs to instruct the staff on storage requirements. He should include the following information:
C. The stock should be rotated so that the oldest vaccines (earliest expiration dates) are in the front. When new vaccines are received, the stock should be rotated, so vaccines and diluents with the earliest expiration date are used first. Refrigerator and freezer temperatures must be recorded in a temperature log twice each workday. The log should be kept for at least three years.
DV is a healthy 66-year-old female. Her PCP believes that she would benefit from receiving both Vaxneuvance and Pneumovax 23. How should the vaccines be sequenced?
C. Vaxneuvance today, Pneumovax 23 in 1 year When both Vaxneuvance and Pneumovax 23 are given to a healthy patient ≥ 65 years old, Vaxneuvance is given first. Wait at least one year before administering Pneumovax 23.
LB is a 45-year-old female with no significant past medical history who is at the pharmacy today to get her annual flu vaccine and specifically requests Flumist. LB asks the pharmacist about the outbreaks of measles and hepatitis A which have been on the local news in the past few months. LB admits she has not been vaccinated against either of these diseases but asks the pharmacist if she can be vaccinated today. Can the patient receive all three vaccines (Flumist, measles and hepatitis A) today?
C. Yes, she can get all three vaccines today. Simultaneous administration (administration on the same day) is recommended whenever possible to increase immunization rates. Although all the indicated vaccines for the patient can each be given, the individual vaccines cannot be mixed in the same syringe unless they are licensed for mixing by the FDA. If live parenteral (injected) vaccines (e.g., measles - MMR or MMRV, varicella, and yellow fever) and the live intranasal influenza vaccine (Flumist) are not administered at the same visit, they should be separated by at least 4 weeks. If more than one injection is given in the same limb, separate the injection sites by at least 1-2 inches. This way, any individual reactions can be observed.
HY is a 77-year-old female with diabetes, heart failure and rheumatoid arthritis. She would like to get a flu vaccine while her prescriptions are filled. Which of the following formulations would not be appropriate for her?
D. FluMist FluMist (the live attenuated influenza vaccine) is indicated for healthy patients age 2-49 years, so it would be inappropriate for this 77-year-old patient.
Select the correct information for the Varivax vaccine.
D. Once drawn up in a syringe, the vaccine must be used quickly. Live vaccines should not be given during pregnancy. The vaccine is stored in the freezer, and the diluent is stored at room temperature or in the refrigerator. Varivax should be reconstituted immediately when removed from the freezer and administered by SC injection right away.
How is influenza spread most commonly?
D. Respiratory droplets, from sneezing or coughing Influenza spreads primarily through respiratory droplet transmission, such as when an infected person coughs or sneezes near an uninfected person.

A mother asks if her 11-month-old son will receive thimerosal from vaccines. She is concerned that this mercury-containing preservative might increase the risk of autism in her son. Select the correct statements. (Select ALL that apply.)
D. Thimerosal may be present in multi-dose influenza vaccines and can be avoided upon request. A link between vaccines and autism has been well-studied and has not been shown in legitimate medical literature.
