Dr.Juliet Otieno, a pediatric medical officer at Kilifi District Hospital says, "We are seeing fewer children coming in with bacterial pneumonia infections than before the PCV10 vaccine was rolled out. It is extremely important that we are actually able to measure the impact of the vaccine."
"As a clinician, my assumption would be that if we have brought in the vaccine and we see a reduction in the cases, then the vaccine is working. But that's an assumption. The study gives us evidence."
In January 2011, the Kenyan government with support from the GAVI Alliance, introduced a new vaccine, PCV-10, which targets 10 bacteria than can cause Invasive Pneumococcal Disease.The vaccine's impact is monitored through an electronic database, part of the GAVI funded PCV impact study, which maps the growing coverage of the new vaccine. Already, here in Kilifi, the incidence of the illness in children aged five has gone down by approximately two-thirds.
