A report has revealed a sharp decline in pneumonia cases in Kenya for the past six years since the introduction of the pneumonia vaccine.

In 2011, with support from Gavi, the Vaccine Alliance, Kenya became one of the first countries in Africa to introduce the pneumonia vaccine and the first country in Africa to introduce the national childhood immunization schedule as a three-dose series administered at 6, 10, and 14 weeks.

The introduction of the vaccine, it is noted, reduced cases of pneumonia by 92 per cent in children below five years. Those between 5 years and 14 years reduced by 81 per cent within the period.

The jab also led to a 27 per cent reduction in childhood hospital admissions with clinically-defined pneumonia and a 48 per cent reduction in childhood hospital admissions with radiologically confirmed pneumonia.
