Prime Minister Narendra Modi on Saturday launched India's Covid-19 vaccination drive and asserted that the made-in-India vaccines being rolled out will ensure a "decisive victory" for the country over the coronavirus pandemic. Addressing the nation ahead of the launch, Modi reminded people that two doses of vaccine are very important and asked them to maintain wearing masks and social distancing even after receiving the jabs. "Dawai bhi, kadai bhi," he said.
