Responding to a fast-spreading measles outbreak, #Bangladesh 🇧🇩 is scaling up an emergency vaccination campaign to protect millions of young lives. By 18 April, over 1.49 million children were vaccinated, with 2.4 million more children to be reached. In a busy vaccination hall, Afrida, 32, holds her children close. “I brought them because I know the vaccine will protect them," she says. WHO and partners are supporting Ministry of Health and Family Welfare to vaccinate and protect every child against the deadly disease. 🔗: who.int/bangladesh/new… #VaccinesWork #Measles #HealthForAll #Immunization

With tighter budgets & growing health challenges, countries must make difficult choices on #vaccines. SAGE stressed need for decisions based on strong evidence from independent national advisory groups & partnership to protect progress. Vaccines are about health not politics.

@ SAGE meeting, experts reviewed state of global immunization. 80% of countries protect people against at least 10 diseases but funding gaps, misinformation & fragile health systems threaten progress. Strong evidence-driven vaccine guidance is essential 🔗shorturl.at/jzITt

Trust is key to strong immunization programmes. @ this week’s SAGE meeting, experts are highlighting the need for reliable information, resilient health systems & confidence in vaccines to ensure every1 benefits from life-saving protection #VaccinesWork 🔗shorturl.at/9iPqB
