# Global measles resurgence and vaccination gaps > Live situation record from CLSTR: https://clstr.news/situations/global-measles-resurgence-and-vaccination-gaps > Updated: 2026-08-22T10:30:00.000Z. Sources: 8. Developments: 2. Health experts are warning of a significant global resurgence of measles, with projections suggesting approximately 11 million people may contract the disease in 2026. This surge is attributed to declining and uneven vaccination coverage across Africa, Asia, Europe, and the Americas, exacerbated by disruptions to routine immunization programs during the COVID-19 pandemic. In Australia, research indicates that approximately 1.7 million people were susceptible to measles as of 2019, with national immunity levels sitting at the bottom of the World Health Organization’s recommended range. Vulnerability is particularly high among infants, young children, and adults aged 15–35. Australian measles notifications have trended upward, rising from single digits in 2022 to 181 cases in 2025, with 113 cases recorded in early 2026. Globally, while outbreaks are concentrated in low- and middle-income countries, the virus has re-emerged in nations with advanced healthcare systems. The World Health Organization emphasizes that a vaccination coverage rate above 95 percent is required to prevent sustained transmission, yet significant gaps in routine vaccination persist despite large-scale immunization initiatives. ## Timeline ### 2026-08-22: Global measles cases projected to reach 11 million in 2026 Global measles cases are projected to reach 11 million in 2026 due to declining vaccination rates, with significant outbreaks reported across Africa, Asia, Europe, and the Americas. 4 sources. https://clstr.news/cluster/global-measles-cases-projected-to-reach-11-million-in-2026 ### 2026-08-17: Australia measles immunity gaps leave 1.7 million people vulnerable A study reveals 1.7 million Australians lack sufficient measles immunity, placing the nation at risk of outbreaks as global cases rise and domestic immunity sits at the low end of WHO targets. 4 sources. https://clstr.news/cluster/australia-measles-immunity-gaps-leave-17-million-people-vulnerable --- Cite as: Global measles resurgence and vaccination gaps.
