The Democratic Republic of the Congo today launched a nationwide vaccination campaign aiming to protect around 62 million children aged 6 months to 14 years against measles and rubella, ahead of introducing the combined vaccine into the national immunization schedule. The single measles vaccine will be replaced by the combined measles-rubella (MR) vaccine in routine immunization, while the catch-up campaign will help close immunity gaps among children and adolescents for both diseases.
