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

> 1.2 million people die from TB every year. New vaccines are within reach & could help tackle the epidemic. TB Vaccine Accelerator is aligning R&D, policy, financing & country preparedness to ensure faster access to future vaccines, especially in high TB burden settings. #EndTB

Today, on #WorldTBDay, the message is clear: Yes! We can end TB. With strong country leadership, investment, innovation, and collaboration, it is possible to turn the tide on the #TB epidemic—even in a challenging global context. Ending TB is achievable. 🔗shorturl.at/jZHyZ

From #typhoid and COVID-19 to #polio, SAGE experts reviewed the evidence on how #vaccines can best protect people in today’s complex world. Reaching zero-dose children, strengthening routine #immunization, and maintaining public trust remain at the core. #VaccinesWork

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

As we look toward @Gavi 6.0, strong global guidance from SAGE remains essential to help countries prioritize vaccines, strengthen programmes, and reach zero-dose children. Partnership and science must guide the path forward. #VaccinesWork 🔗 bit.ly/40T7bPh

The world’s leading vaccine experts are meeting this week @ SAGE to review the latest evidence & guide global immunization policy. Evidence-based recommendations are essential to protect people of all ages from vaccine-preventable diseases. #vaccineswork🔗bit.ly/4rkkPpo

As countries work toward the goals of #IA2030, staying informed on the latest evidence and progress is key. The latest Global Immunization Newsletter brings together updates from across the global immunization community. Read it here: bit.ly/40lPXtK #vaccineswork

#Measles outbreaks are rising, even as #vaccination rates have improved in some countries. @MeaslesRubella’s Midterm Review calls on leaders to strengthen immunization efforts, close equity gaps & invest in outbreak preparedness. 🔗bit.ly/3OW4iuh

New real-world evidence reaffirms RTS,S #malaria vaccine is safe and effective and informs global guidance for how to deliver it to vulnerable children. 🔗bit.ly/3Oy594d

When crises strike, fast access to medicines is vital. @WHO supported @WTO and @WCO to update customs systems so vaccines and essential drugs reach people sooner. #vaccineswork

Fast access to medicines is crucial in times of crisis. @WHO has supported @WTO and @WCO to update the global customs system that classifies vaccines and other health products. This speeds up customs procedures so essential drugs can reach health facilities and people in need during emergencies.
