OBJECTIVES Describe the immunological responses of Prevnar and Pneumovax List the proper timeline for pneumococcal vaccine administration based on age and comorbidities Identify the laws governing pharmacist administration of pneumococcal vaccines

About 900,000 Americans get pneumococcal pneumonia each year with a 5-7% mortality rate 400,000 hospitalizations annually 90% of invasive pneumococcal disease cases in adults >95% pneumococcal deaths occur in adults Combination immunization therapy of Prevnar and Pneumovax Schedules based on: Age Prior vaccination status Immunocompetency BACKGROUND: PNEUMOCOCCAL DISEASE CDC. Pneumococcal Disease. Available at: Accessed July 28, 2015.

TIMELINE PEARLS DO NOT administer together Previously 6-12 month recommended interval PCV13  PPSV23 No data for shorter intervals No immunologic differences between 6 and 12 months Higher incidence of adverse effects with shorter (6 month) interval If Pneumovax is given at a shorter interval than 12 months, no need to repeat it Administer even if had previous pneumococcal pneumonia infection CMS will only cover 2 nd vaccine if 1 year has passed May be co-administered with Influenza vaccine Foster, SL.
