Moving forward with strengthening routine immunization delivery as part of measles and rubella elimination activities.

The Global Vaccine Action Plan includes a goal of meeting global and regional measles and rubella elimination targets, noting that such efforts should not operate in silos but be coordinated with other immunization efforts. Similarly, the Global Measles and Rubella Strategic Plan for 2012-2020 emphasizes the need for integrated approaches to achieve and maintain very high levels of population immunity using both routine immunization and supplemental immunization activities (SIAs). The strategic plan also includes routine vaccination coverage targets, highlighting the critical role of strong routine immunization systems as a cornerstone for sustainable measles control/elimination efforts. It encourages exploiting the resources and visibility of SIAs to strengthen routine immunization, thereby reducing the frequency with which SIAs are needed. Documented examples of doing so include training health workers, procuring cold chain equipment, and improving injection safety and adverse events management. However, the concept has been put into practice only to a limited extent and missed opportunities persist regarding this aspect of SIA planning and execution. This paper draws on recent studies of the interaction between measles activities and health systems as well as country experiences in using SIAs to strengthen routine immunization. It identifies obstacles and enabling factors to doing so and proposes options for systematically strengthening routine immunization as part of a best practice SIA.
