In the months of April and May, India grappled with the devastating second wave of Covid-19. Now, with the speculations about the inevitability of the third wave of Covid-19, the central government has revised the Covid-19 vaccination guidelines in the country. Under the new centralised vaccine policy, India on June 21 (Monday) administered more than 80 lakh vaccine doses, the highest in a single day. However, Delhi, which was one of the worst-hit states by the second wave of the coronavirus outbreak, remained to be one of the worst performers in the country-wide inoculation drive.
