Assistant Professors of Pharmacy Practice
University of Charleston School of Pharmacy
Objectives
• Determine the appropriate vaccine recommendations for a patient
based on current immunization schedules.
• Apply individual vaccine characteristics to identify anticipated
vaccine adverse events.
• Explain the Advisory Committee on Immunization Practices (ACIP)
recommendations for vaccines pharmacists can administer in West
Virginia.
• Summarize critical information needed for the administration of
influenza and pneumococcal.
• Investigate information about the vaccines added to Title 15 Series
12 of the West Virginia Code for immunization rules.
Pharmacist Administered
Immunizations in WV
• HB 3056 passed in 2008 authorizing specially trained
pharmacists in WV to administer influenza and
pneumococcal polysaccharide
• Additional vaccines could be added following joint rulemaking with WV Board of Medicine, WV Board of
Osteopathy, and WV Board of Medicine
• Summer 2011 joint rule-making occurred and was
approved by the 2012 Legislature
• Pharmacists can now administer Hepatitis A, Hepatitis B,
Tetanus, and Herpes Zoster in addition to influenza and
pneumococcal vaccines
Current Title 15 – Series12
• Qualifications for pharmacists to
administer immunizations:
– Any person ≥ 18 years old
– Registered with the Board of Pharmacy (BOP) to
administer immunizations
– Successfully complete immunization training course
approved by the BOP
– Maintain current certification to basic life-support
– Complete 2 hours annually of continuing education
related to immunizations
Current Title 15 – Series12
• Must have immunization questionnaire and consent form, notify
patient’s primary care provider (PCP) within 30 days of
administration
• Report the administration to the WV Statewide Immunization
Information (WVSII) database within 30 days of administration
• Must have consent & questionnaire readily retrievable and
maintained on file for not less than 5 years
• Pharmacists can administer epinephrine and diphenhydramine to
manage acute allergic reaction following CDC guidelines
• Pharmacists must have readily retrievable emergency response plan
as outlined by the CDC and a readily retrievable emergency kit to
manage an acute allergic reaction to an immunization administered
Pharmacists as Immunizers in
WV
• As of June 2012, 1663 pharmacists have
completed the mandated training course and
are registered with the West Virginia Board of
Pharmacy as Immunizing Pharmacists.
• This represents approximately 50% of the
pharmacists practicing in WV.
• This addition to the immunizing workforce
increases the access to immunizations for the
public.
Updates to Title 15 – Series 12
• Adds:
–
–
–
–
Hepatitis A
Hepatitis B
Herpes Zoster
Tetanus (follows CDC recommendations and permits tetanusdiphtheria (Td) or tetanus-diphtheria-pertussis (Tdap)
• Pharmacists must report all adverse
events to the Vaccine Adverse Events
Reporting System (VAERS) and provide a
copy to the BOP (available at
http://vaers.hhs.gov/index)
Case Study 1
• A family comes in to the pharmacy. The mother
is a 40yo WF with a 15yo WM and 19 WF
children requests immunizations for herself and
her family. After discussing with her what she
needs, you determine that they all need TIV and
her daughter needs Hep B.
• What immunizations could the pharmacist
currently provide for the family?
Advisory Committee on Immunization
Practices (ACIP)Recommendations for Adult
Influenza Immunizations
• Vaccination recommended for all adults (including
healthy adults 19-49 years without risk factors)
• Live attenuated influenza vaccine – only approved for
healthy non-pregnant people age 2-49 years
• 65 years and older can get standard-dose Trivalent
inactivated influenza vaccine (TIV) or the high does TIV
• Give 1 dose every year in the fall or winter
• Begin vaccination as soon as vaccine is available and
continue until supply is depleted
• If 2 or more live virus vaccine are given – give same day
or they must be separated by at least 28 days

Pneumococcal disease
• Pneumococcal disease most often occurs in older people as
well as in people with a predisposing condition (e.g.,
pulmonary disease, asplenia).
• Pneumococcal disease most commonly presents as a serious
infection in the lungs (pneumonia), blood (bacteremia), or
brain (meningitis). The annual U.S. case estimate for invasive
pneumococcal disease (bacteremia and/or meningitis) is
40,000.
• PPSV is 60–70% effective in preventing serious
pneumococcal disease; it does not provide substantial
protection against all types of pneumonia (viral and bacterial).
It is not a “pneumonia” vaccine.
Pneumococcal Polysaccharide Vaccination Pocket Guide :

Pneumococcal Polysaccharide
(PPSV)
• Recommended for people 65 years and older; younger
than 65 years with chronic illnesses or other risk factors
(cardiac, pulmonary, liver disease, alcoholism, diabetes,
cigarette smoking); Those at highest risk including
asplenia, immunocompromising condition,
chemotherapy, or has received organ or bone marrow
transplant
• Give 1 dose if history is unknown or unvaccinated
• Give a 1 time revaccination to:
– Age 65 years and older if 1st dose was before age 65 years and
more than 5 years ago

5 years have elapsed since the 1st dose

• Healthy People 2020 goals call for 90 % of the
non-institutionalized adults aged 65 years and
older and 60% of non-institutionalized high-risk
adults aged 18 to 64 years to be immunized.
• Neither overall coverage nor coverage for any
specific age or racial/ethnic group differed
significantly from 2009 coverage.
