NEW DELHI: President-elect Joe Biden said on Friday he would not make the vaccines for Covid-19 mandatory but hoped the public would develop confidence in them over time. “I wouldn’t demand it to be mandatory, but I would do everything in my power just like I don’t think masks have to be made mandatory nationwide,” Biden said. He is expected to name Jeff Zients, a co-chair of his transition and a former Obama economic aide, as his coronavirus “czar” , according to a source. He also said plans for his inauguration next month were being developed with safety in mind. He doesn’t expect the traditional parade or crowds, he said, although there might be a public swearing-in along with more virtual activity. On Friday, US set single-day record with 2,35,272 infections, over onethird of all global cases.
