In vaccines, Merck recently received approval from the U.S. Food and Drug Administration (FDA) for CAPVAXIVE, now the first pneumococcal conjugate vaccine specifically designed to address the serotypes responsible for approximately 85% of invasive pneumococcal disease cases in adults age 65 and older, based on the U.S. Centers for Disease Control and Prevention (CDC) data from 2018-2021. The CDC's Advisory Committee on Immunization Practices (ACIP) unanimously voted to recommend CAPVAXIVE for adults age 65 and older who have not received a pneumococcal conjugate vaccine or whose vaccination history is unknown, for adults 19 to 64 with certain risk conditions, and for adults 19 and older who have started their pneumococcal vaccine series with PCV13. Additionally, shared clinical decision-making is recommended for a supplemental dose of CAPVAXIVE for adults over 65 who completed their vaccine series with both PCV13 and PPSV23.
