Official title: Impact of GSK Biologicals’ 2189242A vaccine on nasopharyngeal carriage, safety and immunogenicity when co-administered with routine EPI vaccines in infants following safety assessment in children aged 2-4 years in The Gambia
Trial description: This study will assess the impact on nasopharyngeal carriage, safety and immunogenicity of GSK Biologicals’ pneumococcal vaccine 2189242A given as a 3-dose vaccination course and co-administered with other routine paediatric vaccines in infants in The Gambia. Two formulations containing different doses of pneumococcal antigen and two different schedules will be tested in infants.
