Bangladesh is facing one of its worst measles outbreaks in recent years, with over 100 children reported dead. Health authorities, supported by the World Health Organization (WHO) and UNICEF, have initiated an emergency measles rubella campaign targeting 1.2 million children. This crisis serves as a stark warning for India, where immunization coverage has improved but still falls short of the 95% threshold necessary for herd immunity. As of 2023, coverage stands at 93% for the first dose and 88% for the second dose, leaving nearly one million children unvaccinated, especially in states like Bihar, Uttar Pradesh, and Madhya Pradesh. Despite significant progress through initiatives like Mission Indradhanush, which has vaccinated 5.46 crore children since 2014, delivery challenges persist. These include mobility constraints and inadequate surveillance systems, which hinder timely responses to outbreaks. To prevent a similar crisis, India must focus on closing immunization gaps, improving surveillance, and ensuring rapid response capabilities, especially in hard-to-reach populations.
