Number of reported measles cases and estimated percentage of MCV1 and MCV2 coverage, by year — Philippines, 1998–2014

Abbreviation: MCV = measles-containing vaccine.

Source: World Health Organization (WHO)–UNICEF estimates of national immunization coverage are available at http://www.who.int/immunization_monitoring/routine/immunization_coverage/en/index4.htm. Estimated coverage with the routine first dose of measles-containing vaccine (MCV1) was among children aged 1 year; estimated coverage with the routine second dose of measles-containing vaccine (MCV2) was among children at the recommended age of administration of MCV2, as per the national immunization schedule. Introduction of MCV2 started in 2009 in Regions 4A, 5, 6, 7, and 12. In 2010, MCV2 was introduced into the routine immunization nationwide; however, reporting was incomplete until the recording/reporting tool was updated in 2012 to accommodate the addition of MCV2. The number of reported measles cases during 1998–2013 is as reported to the World Health Organization (WHO) and UNICEF through the Joint Reporting Form and during 2014 as reported in monthly reports to the WHO Western Pacific Regional Office by December 20, 2014.

* Supplementary immunization activities using measles-containing vaccine were implemented in 1998 (nationwide) for children aged 9 months–14 years, 2004 (nationwide) for children aged 9 months–7 years, 2007 (nationwide) for children aged 9–48 months, and using measles-rubella vaccine in 2011 (nationwide) for children aged 9–95 months.
