Faster vaccination of the population, with more vaccines from wider manufacturers approved with due process, is one clear way of making sure that people are safe from COVID-19, according a senior official of the Tata group. The group is in the process of airlifting 60 cryogenic containers from overseas and building around 400 oxygen generating units that can be used by hospitals in smaller towns to aid combat the devastating second wave of the pandemic. It is also preparing cold chains in case a vaccine requiring low temperature for transportation is approved. "I would say the faster and sooner we are able to get our people vaccinated, the better it would be because it is one clear way of making sure that our people are safe," Tata Sons President (Infrastructure, Defence, Aerospace and Global Corporate Affairs) Banmali Agrawala told PTI.
