Despite high awareness around seasonal flu, vaccination uptake in India remains low — largely due to complacency and the familiar 'ho jayega' mindset. With the launch of Vaxiflu-4, India's first quadrivalent flu vaccine, Zydus set out to normalise flu vaccination as a yearly health habit, not a crisis-driven decision.
Instead of fear-based medical messaging, the campaign introduced a culturally intuitive nudge: 'Flu Vaccine Liya Kya?' — a line that sounds like everyday small talk, yet carries real preventive intent. By reframing vaccination as a simple social check-in — much like asking about food, travel, or health — the campaign transformed a medical action into a conversational habit.
Radio became the lead medium for this behavioural shift. Through slice-of-life storytelling, routine daily questions were replaced with one that truly mattered, cutting through clutter with warmth, familiarity, and repetition. Partnering with Radio Mirchi, multilingual, high-frequency spots were rolled out across prime cities and time bands to drive recall at scale.
The conversation was extended beyond airwaves through RJ-led social content, where trusted radio voices carried the message into digital spaces with credibility and relatability. By making prevention sound human, familiar, and timely, the campaign successfully turned flu vaccination into an everyday conversation.
