Health workers of Assam have been taking risky boat rides down the flooded Brahmaputra to remote riverine islands to vaccinate people against COVID-19. It is part of the the state's major vaccination push to provide shots to every resident. NDTV's Ratnadip Choudhury and Sanjay Chakraborty travelled with one such vaccination team on the Brahmaputra and its tributary to see how the workers are pulling off this feat.
