Pneumococcal pneumonia vaccine
Brief summary
The World Health Organization has recommended that developing countries should incorporate pneumococcal conjugate vaccine (PCV) into their routine immunization schedules. The Kenya Ministry of Health anticipates introducing a new formulation of PCV, PCV10, into the routine childhood immunization schedule in 2010. In the areas of Kenya that have been designated to monitor the impact of vaccine, a catch-up campaign will be implemented to vaccinate children aged 12-59 months. PCV10 has been found to be safe and effective in infants. It is licensed for use in children up to 2 years of age, but its use as a primary series in children over age 12 months has not been evaluated. This study will assess the immunogenicity and reactogenicity of PCV10 first administered at an age of 12-59 months.
Interventions
A nurse will administer a 0.5mL intramuscular dose of PCV10 on day 0 and day 60 and a 0.5 mL intramuscular dose of DTaP on day 180.
A nurse will administer a 0.5mL intramuscular dose of hepatitis A vaccine on day 0 and day 180; a 0.5 mL intramuscular dose of DTaP on day 60; and a 0.5 mL dose of PCV10 on day 180.
