MEASLES VACCINATION HAS SAVED AN ESTIMATED 17.1 MILLION LIVES SINCE 2000

Success of immunization campaigns

In 2014, mass vaccination campaigns led by country governments with support from the Measles & Rubella Initiative and Gavi, the Vaccine Alliance, reached approximately 221 million children. Twenty-nine countries supplemented their routine vaccination programmes with mass immunization campaigns, helping to reduce measles incidence in 4 out of 6 WHO regions last year. Overall, since 2000, these campaigns have enabled 2 billion children to receive a supplemental dose of measles vaccine.

In the African Region, cases dropped from over 171 000 in 2013 to under 74 000 in 2014, likely due to campaigns in Democratic Republic of the Congo (DRC) and Nigeria. WHO’s Eastern Mediterranean, European and the South-East Asia regions also saw decreases in measles incidence in 2014.

Large-scale campaigns in 2014 included:

• Bangladesh - more than 53.6 million children vaccinated

• DRC - more than 18.5 million children vaccinated

• Pakistan - more than 25 million children vaccinated

• United Republic of Tanzania - more than 20.5 million children vaccinated

• Yemen - more than 11.3 million children vaccinated

• Viet Nam - more than 15.1 children vaccinated

“Last year, the Measles and Rubella Initiative supported campaigns in 29 high-risk countries to stop measles, including in Liberia where a serious outbreak occurred following the Ebola epidemic. Funding for many of the largest campaigns came from Gavi, the Vaccine Alliance. Gavi’s support for measles campaigns in large countries like DRC and Pakistan, and measles-rubella vaccine introduction through campaigns targeting children under 15 years of age, is providing a strong boost to measles control and elimination in those countries, “ says Dr Robert Linkins, Chief, Accelerated Disease Control and Surveillance Branch at the U.S. Centers for Disease Control and Prevention.

“Despite our success in these countries, globally over 100 000 children needlessly died from measles last year. That’s a tragedy which can be easily prevented if we intensify our measles surveillance and vaccination efforts,” Linkins concluded.

Measles outbreaks remain an issue

Measles outbreaks, which happen when there are gaps in vaccination programmes, continue to pose a serious challenge to meeting global targets. The Americas and Western Pacific regions saw increased numbers of cases in 2014, mostly due to large outbreaks in China, the Philippines, and Viet Nam. In other regions, although the overall number of cases fell, some individual countries still had large outbreaks, including Angola, Ethiopia, India, the Russian Federation and Somalia.

Accelerating progress

Measles is highly infectious and strong, sustained efforts are needed to maintain the current level of control. Together with changes in policies and practices in high-burden countries, vaccination and surveillance efforts need to be funded, maintained and strengthened, WHO and its partners say.

“Despite the welcome reduction in measles deaths, this highly-infectious disease continues to take a terrible toll on the lives of children around the world,” said Dr Seth Berkley, CEO of Gavi, the Vaccine Alliance. “A coordinated approach that puts stronger routine immunization at its core will be central to getting measles under control and securing further reductions in mortality from this vaccine-preventable disease.”
