Indians will no longer be greeted by a caller tune that began with a coughing sound, followed by a cautionary note on Covid-appropriate behaviour by actor Amitabh Bachchan. Now, as the country gears up to launch its massive vaccination drive on Saturday, the mandatory caller tune is being replaced with a one that seeks to educate people about vaccination. The new caller tune stresses on the importance of vaccines and urges people not to believe on rumours related to them. The new year has brought a new ray of hope in the form of vaccines’, the voice says. The caller tune then adds that vaccines developed in India are safe and effective against the viral disease.
