In Pakistan, a silent and dangerous pandemic is spreading not transmitted through the air, but through WhatsApp and rumours in the community. It is a pandemic of false information that undermines trust in one of the most powerful tools of modern medicine and leaves the nation vulnerable to preventable diseases. From the ongoing war against polio to the recent rollout of the Covid-19 vaccine, fake news has proven to be just as strong a opponent as any virus. It has directly cost lives and pushed public health efforts back by decades.
The human cost is devastatingly real. Pakistan is one of the last two countries where the wild polio virus is still present, and this is unresolvable linked to profound vaccine hesitancy. A major turning point came in April 2019, when a viral video falsely showed children collapsing after receiving polio drops. This digital lie fueled real-world violence, including an attack on a hospital in Peshawar, and vaccine refusals exploded from 256 in one district in March to 88,000 in April. The campaign was suspended nationwide, and millions of children were left unprotected in its wake.

This incident dramatically highlights how a single piece of misinformation can destroy a decades-long eradication effort. Similarly, during the Covid-19 pandemic, conspiracy theories such as the virus being a foreign bio weapon, or the vaccine containing microchips or causing infertility created widespread reluctance in the public. Surveys showed that about two out of five Pakistanis were hesitant to get the Covid-19 vaccine, compromising the national effort to achieve herd immunity and reduce the pandemic’s toll.
The roots of this distrust are complex and historical. With increasing internet penetration, platforms such as WhatsApp and Facebook have become major vectors for misinformation, where emotionally charged falsehoods about ingredients, side effects, and conspiracies spread rapidly and more widely than factual corrections. These narratives are often tailored to local religious and cultural sensitivities for example, false claims about forbidden animal derivatives in vaccines making them especially potent and difficult to dismiss.
Combating this crisis requires a strategic and multi-pronged approach, with trust not just facts at the center. First, engagement must come from credible local voices. The support of religious leaders has played a key role in declaring polio vaccination permissible (halal) and a moral obligation. When a federal health minister publicly vaccinated his own daughter against HPV in response to early rumours, it demonstrated powerful leadership. Second, the digital battlefield cannot be abandoned. Public health authorities must be proactive and strategic in using the same social media platforms to spread clear and compelling content, preemptively debunking common myths using local languages and cultural references. Third, the vaccination system itself must operate with unimpeachable integrity. Reports of logistical failures such as improper vaccine storage or falsified records can destroy community trust as effectively as any external rumour. Ensuring transparency, professional excellence, and accountability within the health system is the essential foundation for all communication.
Ultimately, for Pakistan, the battle against vaccine misinformation is a battle for the country’s health security. It is a complex struggle shaped by historical grievances, digital manipulation, and genuine fear. It will not be one campaign that creates change, but long-term, honest, and collaborative efforts that place community trust at the forefront. By empowering local leaders, innovating digital communication, and guaranteeing complete transparency in health services, Pakistan can protect its population not just from disease, but from the dangerous contagion of misinformation. The health of future generations depends on this critical endeavour.
