Sources: 58. Developments: 9. The resurgence of measles in the Balkan region continues to drive public health responses and intense social debates. In Serbia, confirmed cases have reignited polarized discussions on social media regarding misinformation. In Montenegro, the September 1, 2026, law requiring vaccinated children to attend kindergartens has caused administrative friction. Parents have reported confusion over documentation and a lack of appointments, with some facilities reportedly attempting to separate unvaccinated children into different classrooms. While Snežana Mugoša of CInMED affirmed that vaccines are “high-quality, safe, and effective,” the policy has sparked debate. The Constitutional Court has scheduled a hearing for September 15. In Croatia, authorities are pursuing legal action against parents refusing routine vaccinations. The State Inspectorate reported 55 misdemeanor proceedings since 2024, with the Ministry of Justice recording 23 new proceedings since the start of 2025. Regional health risks are escalating. In Bosnia and Herzegovina, the Institute for Public Health of Sarajevo Canton issued a warning to parents regarding the spread of the disease, noting its high contagiousness in environments with low vaccination rates like schools. This warning follows confirmed cases in Croatia, which officials linked to travel from Kosovo, where infection numbers have also increased. Authorities urge parents to ensure the MRP vaccine is administered according to schedule to avoid leaving children unprotected. In Albania, the National Institute of Public Health reported 151 confirmed cases between April 16 and August 30, with over 95% occurring in unvaccinated individuals.
