AIIMS director Dr Randeep Guleria speaks to NDTV about the second phase of India's COVID-19 vaccination drive, cost and concerns over spike in cases even as inoculations are going on. "We may have 3-4 vaccines in a few weeks," Dr Guleria said, adding Johnson & Johnson's vaccine approval is good news for the global vaccination campaign. Dr Guleria asked people to come out in large numbers to get vaccinated, not fall for misinformation and beat "vaccine hesitancy".
