UK measles and rubella elimination

Measles and rubella can be eliminated and congenital rubella infections prevented by achieving high uptake of the combined measles, mumps and rubella (MMR) vaccine in national childhood immunisation programmes. All Member States of the World Health Organization (WHO) European Region have a longstanding commitment to eliminating measles and rubella and this is a core goal of the European Vaccine Action Plan 2015 to 2020. In the UK the MMR vaccine is offered to all children at 1 year of age, with a second dose given at 3 years and 4 months.

UK Health Security Agency is responsible for collating and submitting evidence every year, on behalf of the devolved administrations (England, Wales, Scotland and Northern Ireland), to the UK national verification committee (NVC) and the WHO Regional Verification Commission for Measles and Rubella Elimination (RVC) for review and evaluation on an annual basis.

The elimination verification process is based on evidence documented by each Member State to show whether interruption of endemic transmission of measles and/or rubella at national level has been achieved and, if not, that a national plan has been developed to address this.

The following essential criteria are required to verify elimination of measles and rubella in the UK:

  • the absence of endemic measles and rubella cases for a period of at least 12 months from the last known case, due to complete interruption of endemic virus transmission
  • the presence of a high-quality surveillance system that is sensitive and specific enough to detect, confirm and classify all suspected cases
  • genotyping evidence that supports the interruption of endemic transmission

The WHO confirmed that the UK achieved elimination status for rubella in 2016. After briefly achieving measles elimination in 2016 and 2017, since 2018 the UK has re-established transmission of measles virus. See Tables 1 and 2.

This measles blog by Dr. Vanessa Saliba explains why are we still seeing measles cases in the UK. Measles elimination can only be achieved and maintained by reaching 95% coverage with 2 doses of the MMR vaccine in children and by using all opportunities to catch up older children and adults who missed out when they were younger.
