13‐valent pneumococcal conjugate vaccine (PCV13) is immunogenic and safe in children 6‐17 years of age with sickle cell disease previously vaccinated with 23‐valent pneumococcal polysaccharide vaccine (PPSV23): Results of a phase 3 study

Abstract

Children with SCD who were previously vaccinated with PPSV23 responded well to 1 PCV13 dose, and a second dose did not increase antibody response. PCV13 antibodies persisted above pre-vaccination levels for all serotypes 1 year after dose 2. Children with SCD may benefit from at least one dose of PCV13.
