 The mass vaccination campaign against COVID-19 has been a major challenge due to the spread of misinformation and vaccine hesitancy. In order to address this issue, it is essential to work closely with faith-based organizations, FBOs. This paper discusses the experience of working with 18 FBOs and over 400 religious institutions to promote vaccinations and build trust in the vaccination program. Through this collaboration, a sustainable network of sensitized FBOs from different faiths was established. These FBOs were able to reach out to their respective communities and provide them with information about the vaccines and dispel any myths associated with it. As a result, they were able to successfully vaccinate 0.41 million people. This article was authored by Gopal Krishna Soni, Anu Mekha Bhatnagar, Anil Gupta, and others.
