Guides immunization administration with screening, scheduling, and documentation requirements. Use when administering vaccines, screening for contraindications, or documenting immunizations.
Guides immunization administration with screening, scheduling, contraindication assessment, and documentation requirements per CDC Advisory Committee on Immunization Practices (ACIP) recommendations.
Pharmacist-administered immunizations have expanded dramatically since the early 1990s, and all 50 states now authorize pharmacists to administer vaccines. During the COVID-19 pandemic, the PREP Act expanded pharmacist immunization authority further, and pharmacists administered over 300 million COVID-19 vaccine doses nationwide. Pharmacists are the most accessible healthcare providers—90% of Americans live within 5 miles of a community pharmacy—making them critical to achieving Healthy People 2030 immunization targets.
The CDC's Advisory Committee on Immunization Practices (ACIP) publishes the annual recommended immunization schedules for children, adolescents, and adults. Pharmacists must screen for contraindications and precautions, administer vaccines per manufacturer specifications (route, site, needle gauge), observe patients for immediate adverse reactions, document in state immunization information systems (IIS), and report adverse events through the Vaccine Adverse Event Reporting System (VAERS). The National Childhood Vaccine Injury Act (NCVIA) requires provision of Vaccine Information Statements (VIS) before administration. Errors in immunization—wrong vaccine, wrong route, improper storage (cold chain break)—compromise protection and may require revaccination.
Adult immunization schedule (key vaccines and indications):
| Vaccine | Routine Schedule | Special Populations |
|---|---|---|
| Influenza (IIV/LAIV/RIV) | Annually, all adults | Egg allergy: RIV4 or IIV4 (any severity); LAIV contraindicated if immunocompromised |
| Td/Tdap | Tdap once (if not received), then Td/Tdap q10y | Tdap during each pregnancy (27-36 weeks) |
| Pneumococcal (PCV20 or PCV15+PPSV23) | Age ≥65 or risk conditions | PCV20 preferred one-dose series; PCV15 followed by PPSV23 if used |
| Shingles (RZV) | Age ≥50 (2-dose series, 2-6 months apart) | Preferred over ZVL; safe in immunocompromised |
| Hepatitis B (Hep B) | All adults 19-59; risk-based ≥60 | PreHevbrio (3-dose) or Heplisav-B (2-dose) for adults |
| HPV | Through age 26 (catch-up to 45 shared decision) | 2-dose series if started before age 15; 3-dose if ≥15 |
| COVID-19 | Per current CDC recommendations | Updated formulation per circulating variant; immunocompromised may need additional doses |
| RSV | Age ≥60 (shared clinical decision); pregnancy (32-36 wks) | Seasonal administration (Abrysvo or Arexvy) |
| Meningococcal ACWY | Risk-based (asplenia, complement deficiency, travel) | Required for college dormitory residents in many states |
| Meningococcal B | Risk-based or shared clinical decision (ages 16-23) | Two or three dose series per product |
