Immunization campaigns against measles and rubella have improved routine immunization systems and disease prevention measures

A survey of 23 countries in all WHO regions found that activities to eliminate measles and rubella, including vaccination campaigns, have strengthened the countries’ overall routine immunization systems in a number of ways. These include microplanning that led to revised catchment populations and denominators for target-age children, expansion of cold chain systems that extended the reach of immunization, strengthening of surveillance and of outbreak preparedness and response for vaccine-preventable and other diseases.
