Even as the government plans to roll out the Covid vaccination drive with Oxford-AstraZeneca’s Covishield and Bharat Biotech’s Covaxin, recipients may not have an option to choose which one they want to be inoculated with. Hinting that this might be the case in India too, health secretary Rajesh Bhushan said many countries across the world are using more than one vaccine and there is no such option available to any of the beneficiaries in these countries. Covid vaccination in the country is voluntary though whether healthcare and frontline workers have such an option could be a matter of rules.
