Prime Minister Narendra Modi addressed the nation through his monthly radio programme on March 28. During the 75th episode for 'Mann Ki Baat', PM said, "The world's biggest vaccination program is underway in India, today. In UP's Jaunpur, a 109-yr-old woman got herself vaccinated. Similarly, a 107-yr-old man in Delhi got himself vaccinated. We have to make people committed towards the mantra of 'Dawai bhi, Kadai bhi'.
