Cases soar to second-highest in the world as religious fears and social media myths deter parents.
Indonesia is battling a major measles resurgence, fuelled by vaccine hesitancy driven by misinformation and religious concerns, even as the government pushes emergency campaigns to meet now‑unlikely eradication targets.
Record Caseload And Renewed Threat
Measles cases in Indonesia more than doubled from 2024 to over 63,000 in 2025 with 69 deaths, and more than 8,000 suspected cases and 10 deaths were logged in the first quarter of 2026, making Indonesia the world’s second‑worst hit country after Yemen. A January paper in the Indonesian Journal of Internal Medicine warned that measles, once near elimination, has “returned as a significant public health threat.”
Misinformation And Urban Anti-Vax Voices
Stay‑at‑home mother Fitri Fransiskha, who refuses to vaccinate her four children after her firstborn developed a post‑jab fever, typifies parents swayed by online myths that vaccines cause paralysis, behavioural problems or worse. Legislator Putih Sari has flagged that anti‑vaccine sentiment is rising in urban areas, with a Drone Emprit study finding anti‑vax rhetoric across major platforms and data chief Ismail Fahmi noting that a vocal minority of anti‑vaxxers—and influencers selling “herbal” alternatives—drown out pro‑vaccine messages.
Herd Immunity Eroded
AFP fact‑checkers have debunked claims that catching measles offers better protection than vaccines, but epidemiologist Dr Riris Andono Ahmad says such misinformation has “compromised herd immunity.” Only just over three‑quarters of Indonesian children have received both doses of the measles‑rubella (MR) vaccine, far short of the 95 per cent coverage needed to prevent easy spread, leaving many infants and communities exposed.
Religious Concerns And Halal Assurances
In the Muslim‑majority country, some parents reject vaccines over fears of porcine‑derived components; Makassar entrepreneur Yusran, for example, has not vaccinated any of his five children, insisting they are healthy without it. This persists despite a 2018 fatwa from the Indonesian Ulema Council ruling vaccines permissible—even if they contain porcine gelatine—when needed to protect population health, highlighting gaps between official religious guidance and community beliefs.
Government Response And Stalled Eradication Goal
Aiming to eradicate measles and rubella by 2026, the government launched an emergency mass campaign in March across about 100 regencies, including MR boosters for more than 220,000 health workers, and is partnering religious organisations to promote vaccination. Immunisation director Indri Yogyaswari says spread has “dropped a lot” in targeted areas, yet the Health Ministry recorded a 10‑point fall in first‑dose MR coverage in 2025 versus 2024, leaving the eradication goal looking out of reach.
Indonesia’s measles resurgence shows how quickly a once‑controlled disease can roar back when misinformation, fear and religious misunderstanding erode trust in vaccines. For Indonesians and Singaporeans, the lesson is clear: strong, locally trusted communication, religious engagement and easy access to safe vaccines are essential if herd immunity is to be rebuilt and preventable childhood deaths and disabilities are to be averted.
