Kenya kicked off a 100-day periodic intensification of routine immunization (PIRI) campaign on November 1, with the goals of vaccinating at least 95% of children ages 9-59 months against measles, 70% of adolescent girls ages 10-14 against HPV, and, in eligible counties, reducing malaria vaccine drop out between the third and fourth dose from 30% to 10%. The nationwide PIRI campaign, running through February, is taking place in 8,000 immunization facilities in 47 counties, as well as through outreach efforts in schools and community settings.
