The purpose of this study is to assess the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following primary vaccination of Mexican infants with pneumococcal conjugate vaccine GSK 1024850A co-administered with a diphtheria, tetanus, acellular pertussis (DTPa)-combined vaccine (Infanrix hexa) and rotavirus vaccine (Rotarix) in children during the first 6 months of age.

The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
