Will adults need additional pneumococcal conjugate vaccines in the future?

Welcome to Immunize.org’s Ask the Experts resources. This Ask the Experts question is presented by Immunize.org’s Kelly L. Moore, MD, MPH. Question: Will people vaccinated at age 50 need additional doses of pneumococcal conjugate vaccine, or “PCV,” in the future?  Answer: It is likely that an additional pneumococcal vaccination will be recommended at some time in the future. Effectiveness of pneumococcal polysaccharide vaccine (PPSV23) begins waning significantly after about 5 years. While current pneumococcal conjugate vaccines (abbreviated PCVs) are expected to remain effective longer than that, a future PCV dose may be needed by those vaccinated at younger ages to boost protection later in life. When ACIP voted to lower the routine PCV vaccination age to 50, the committee took into consideration that an additional dose, perhaps 10 or 15 (or more) years later, may be needed. In coming years, ACIP will periodically review any evidence of waning protection, evaluate future pneumococcal vaccine products, and make recommendations for revaccination of older adults when needed.
