A quantitative map of global measles vaccination coverage is available

between 2010 and 2019, measles vaccination coverage declined in more than half of low- and middle-income countries, according to an epidemiological study published in the British journal Nature. As a result, there were more than 17 million measles cases and 834,000 deaths among children under 5 years of age in 2017.
and effective measles vaccine, which has been recommended worldwide since 1974. However, the number of measles cases and deaths among children reached a new high in 2017. Widespread measles outbreaks are beginning to occur in areas such as the United States and Europe. Some countries have even recorded the highest number of cases since the advent of the measles vaccine, with the United States, Japan, South Korea and other countries that have announced the elimination of measles re-emergence.
, many cases occur in low- and middle-income countries. Figures for 2019 show that the vast majority of measles deaths occur in countries with low per capita income and weak health infrastructure, with the current measles vaccination rate at just 58 per cent in madagascar, where the outbreak is severe. Globally, therefore, annual comparative local estimates of routine first doses of measles-containing vaccine coverage are critical to an accurate understanding of local immunization patterns, progress towards the Goals of the Global Vaccine Action Plan, and high-risk areas where vaccination programmes have been disrupted as a result of neo-corona pneumonia.
, Jonathan Moser of the University of Washington and colleagues here have come up with an annual estimate of measles vaccine coverage for routine children in 101 countries from 2000 to 2019. They quantified geographical inequalities and assessed vaccination status by geographic remoteness. The team showed that after widespread increases in vaccinations between 2000 and 2010, vaccine coverage declined in more than half of the regions between 2010 and 2019, leaving many low- and middle-income countries far from the Global Vaccine Action Plan's goal of reaching 80 percent coverage in all regions by 2019. Vaccination coverage is lower in rural areas than in urban areas, although a larger proportion of unvaccinated children generally live in urban areas. The three areas with the lowest measles vaccine coverage in 2000 were Harirasu in Ethiopia, Gabilasu in Gabilasu and Issa in Nigeria. In 2019, the three lowest coverage areas are located in Afghanistan.
team concluded that their findings could serve as a tool for policy makers to provide equal protection for all children worldwide in immunization programmes.
