Vivek Agnihotri, director of 'The Vaccine War,' has announced a 'buy 1 get 1' ticket offer for the movie. The film has been doing well at the box office and Agnihotri wants to show appreciation to the audience. He encourages viewers to bring a friend or give the free ticket to someone in need. This offer is not uncommon, as Shah Rukh Khan recently did the same for the film 'Jawan.' 'The Vaccine War' stars Nana Patekar, Anupam Kher, and others, and is based on the book 'Going Viral: Making of Covaxin.'
