In the narrow, muddy lanes of Ghorabari, Sindh, Ali Muhammad’s motorbike brings hope and medical science to the most remote communities. Over the last two decades, Ali has been navigating this marginalized landscape, where accessing healthcare can be a daily struggle. Ali is one of over 15 000 skilled vaccinators trained by the World Health Organization (WHO) under the leadership of Pakistan’s Expanded Programme on Immunization.

His mission: to ensure every child completes their full vaccination course, staying protected from vaccine-preventable diseases that could lead to lifelong disability or death.

Day after day, Ali fights a burden of diseases that particularly threatens communities living in makeshift houses far from health facilities.

WHO’s collaboration with Pakistan and partners – supported by donors like Gavi, the Vaccine Alliance – provides the infrastructure, training, and tools needed to record the vaccination status of children and reach those living in the most isolated areas.
