Tamil Nadu administered 22 lakh doses on Sunday as part of its fifth mega vaccination camp. The state's sero prevalence rate has also touched 70 per cent % in a survey done after the second wave around May. This is more than double the 29% SEROPOSITIVITY in April. Calling this a clear indication of a herd immunity build up, the state government however says the time is not right yet to lift restrictions on places of worship during weekends. NDTV's Sam Daniel spoke to Tamil Nadu Health Secretary Dr J Radhakrishnan who says religious gatherings could turn into super spreaders this festive season.
