1. Serotype replacement by non-vaccine serotypes in circulating pneumococci among healthy young children in Hong Kong was evident after introduction of pneumococcal conjugate vaccine into the childhood immunisation programme.
2. The predominant carriage serotypes were serogroup/type 15 and 6C.
3. Further monitoring and evaluation of these and other emerging serotypes among invasive disease and carriage isolates are warranted.
