More than 80 lakh vaccine doses, the highest in a single day, were administered across the country on Monday as the revised guidelines for Covid-19 vaccination came into effect, the Union Health Ministry said. India’s cumulative Covid-19 vaccination coverage has reached 28.33 crore since January 16, it said. The previous single-day record was of over 48 lakh on April 1. In June so far, India saw an average vaccination of around 31 lakh per day. The average single-day vaccinations fell to as low as around 16 lakh in the first week of May when the country was at the peak of the second wave.
