Vaccination recommendation. In the Practice Guideline “ACIP Approves 2023 Child/Adolescent and Adult Immunization Schedules” (March 2023, p. 319), the recommended schedule for pneumococcal vaccination for adults younger than 65 years was not clearly stated. The first sentence of the second paragraph in the Pneumococcal Vaccination section (p. 321) should have read, “For adults younger than 65 years with certain risk factors (Table 2²), either PCV15 and then PPSV23 after eight weeks, or a single PCV20 are recommended.” The online version of this Practice Guideline has been corrected.
