In a world where diseases like polio still threaten children's lives, one country is fighting back with an unlikely weapon: radio waves. Mozambique, a nation grappling with a polio outbreak since 2022, has harnessed the power of community radio to reach its vast and diverse population, ensuring that life-saving vaccination messages resonate even in the most remote villages. But here's where it gets fascinating: how can a medium as traditional as radio compete with modern challenges like vaccine hesitancy, geographical barriers, and cultural diversity?
Imagine a small village in Inhambane province, where the rustling of grass roofs and the laughter of children are accompanied by the faint hum of a radio. This isn’t just background noise—it’s a lifeline. In Mozambique, where television is a luxury for many, radio remains the most accessible and trusted source of information. Nearly 300 miles away, in the bustling capital of Maputo, broadcasters like Stela Mapanga craft programs for 86 community radio stations, each tailored to the unique languages and cultures of Mozambique’s provinces. Shows like Field of Development and Health and Life become platforms for health education, especially during vaccination campaigns.
“Radio is the heartbeat of communication in Mozambique,” explains José Trindade, chief of the technical department at the National Educational Radio and Television of Mozambique’s Institute of Social Communication (ICS). “It’s affordable, uses local languages, and reaches millions—making it the perfect tool to combat polio.” With an estimated 18 million people tuning in, radio isn’t just a medium; it’s a movement.
But here’s where it gets controversial: In a country where polio re-emerged after a 30-year absence, some question whether radio alone can overcome deep-rooted mistrust and logistical hurdles. Mozambique’s battle began in 2022, when a case of wild polio was confirmed in a three-year-old girl in neighboring Malawi. Within months, the virus crossed borders, paralyzing a boy in northern Mozambique. By the end of that year, eight more children were disabled, and the outbreak was traced back to Pakistan, one of the last polio-endemic countries.
Polio, a highly contagious virus spread through contaminated water and food, has no cure. It primarily affects children under five, causing irreversible paralysis. Mozambique’s Ministry of Health, alongside UNICEF, the World Health Organization, and other partners, launched targeted vaccination drives, administering oral polio vaccines to millions. By May 2024, the wild polio outbreak was contained, but the fight against its variants continues with the nOPV2 vaccine.
And this is the part most people miss: Reaching every child in Mozambique is a herculean task. Vaccinators must navigate conflict zones, displaced populations, porous borders, and the ravages of climate change. Cyclones and violence have even damaged radio equipment, disrupting communication in remote areas. Yet, within this chaos, community radio remains a “strategic ally,” says Denizia Pinto, UNICEF’s social behavior change coordinator. “We use a multichannel approach—TV ads, text messages, loudspeakers on motorbikes—but radio stands out as a trusted voice in rural communities.”
Broadcasting in Portuguese and over 40 local languages, ICS presenters like Mapanga tackle health topics, from cholera to healthy eating. Ahead of the 2025 polio vaccination rounds, which achieved 92% coverage, doctors and health directors became radio stars, debunking myths and emphasizing the importance of vaccination. “I produced a program highlighting polio’s consequences and the need for prevention,” Mapanga shares. “Vaccination is our only shield.”
Radio journalists don’t just inform—they engage. Programs like Rádio Comunitária Mocuba feature expert interviews, vaccine access details, and phone-in segments for questions. “We create space for interaction,” Mapanga notes. “Even listeners who call in become part of the conversation.”
But here’s the counterpoint: As vaccination campaigns progress, some parents question the need for repeated doses. Radio hosts address this by explaining how boosters strengthen immunity. Slogans like “Vaccinate and protect. Let’s guarantee a polio-free future” echo across airwaves, alongside ads stressing the vaccine’s safety and accessibility.
Mozambique’s approach goes beyond radio. Social listening exercises identify community concerns, while partnerships with trusted voices tailor messages to local contexts. When the vaccination target shifted from under-5 to under-15, communication strategies adapted, directly engaging older children. This year, inclusivity took center stage, with campaigns targeting fathers as well as mothers. “Vaccination is a collective responsibility,” Pinto emphasizes.
The results speak for themselves. Recent data show that 90% of surveyed individuals learned about polio campaigns through community radio, among other sources. In Inhambane, parents cite radio as a key reason for vaccinating their children.
But here’s the question we leave you with: In an age of digital innovation, can traditional tools like radio remain effective in global health battles? Or do we need to rethink our strategies entirely? Share your thoughts in the comments—let’s spark a conversation that could shape the future of public health.
