Recently Sundaram Finance Group launched a COVID-19 vaccination awareness drive targeting rural areas of Tamil Nadu, and as a part of this campaign a track titled Oosingo was unveiled. Composed by Anirudh and penned by rapper Arivu, Oosingo became a listener's favourite in no time. 

The song's music video shows Anirudh and Arivu as super-hero versions of Covishield (AstraZeneca-Oxford) and Covaxin (Bharat Biotech), the two vaccines that are widely used in India and singing out the do and don'ts of vaccination beliefs. Director Ajay Gnanamuthu has directed this video, which Sundaram Finance Executive Vice Chairman Harsha Viji believes could help them aim for a 100% vaccination in the state. 

Managing Director of Sundaram Finance Rajiv Lochan has added, "As the number of first doses are seemingly decreasing (in Tamil Nadu), we feel that this is the opportune time to double down and motivate people to get vaccinated. ‘Oosingo’ is our way of driving the community to think about getting the jab.”
