Door-to-Door Polio Vaccination in Mozambique: How Heroes Save Lives One Drop at a Time (2026)

A Life-Changing Journey: Mozambique's Doorstep Polio Vaccination Campaign

In the remote villages of Mozambique, a remarkable story unfolds. It's not just about delivering a vaccine; it's about saving lives and creating a brighter future. Imagine a team of dedicated healthcare workers, armed with more than just a vaccine - they carry the power to protect and the gift of a name.

In a heartwarming encounter, a newborn, just a week old, was given a name by the very people who came to vaccinate him. Little Evanildo, as he was named, became one of the millions of children in Mozambique's national polio campaigns, a campaign that went the extra mile to reach every child.

But here's where it gets controversial: for many, this was a booster dose, but for others, it was their first-ever vaccine. How is that possible? Jan-Marcus Hellström, UNICEF's polio team lead, sheds light on this. "It's not about vaccine hesitancy," he explains, "but about convenience." And this is where the campaign's unique approach shines - by going directly to the children, they make immunization accessible.

Mozambique's struggle with under-immunization is a complex issue. Disruptions caused by COVID-19, natural disasters, and disease outbreaks have led to a rise in unimmunized children. From 97,000 in 2019 to a staggering 750,000 by late 2023, the numbers are a stark reminder of the challenges faced.

"Zero-dose kids" - a term used to describe children who have never received a vaccine - are a vulnerable group. Hellström emphasizes, "They've been left out, and they are more susceptible to diseases."

During outbreak campaigns, these children are prioritized for full immunization. "They could be the key to an outbreak's spread," Hellström adds, highlighting the importance of finding and vaccinating these children.

Community health workers, like Maria Mario, are the backbone of Mozambique's immunization mission. With a passion for health and a heart for children, Mario administers vaccines with a sense of relief and joy. "I do it from the heart," she says, "because these immunizations strengthen us."

During the national polio campaigns, Mario's dedication was evident as she tirelessly tracked down children who needed the vaccine. Her work extended beyond polio, discussing routine immunization schedules with families and ensuring access to other healthcare services.

The impact of these campaigns goes beyond polio. In regions like Madagascar, outbreak responses have been tailored to address regional health issues. The Global Polio Eradication Initiative's strategy includes co-delivery of vaccinations and coordination with agencies like GAVI to strengthen routine immunization.

For Maria Mario, vaccines are a life-saving measure. "The polio vaccine prevents infantile paralysis. It's that simple," she says. And while targeted responses are necessary during outbreaks, routine immunization is the key to a polio-free world.

"An unvaccinated child anywhere is a threat to children everywhere," Hellström emphasizes. This powerful statement underscores the global impact of local efforts.

This story is a testament to the dedication and hard work of healthcare workers like Maria Mario, who go above and beyond to ensure a healthier future for Mozambique's children. It's a reminder that sometimes, it takes more than just a vaccine - it takes a community, a passion, and a commitment to change.
