Following the national findings, states have also been releasing their serosurvey results which again brings the issue of 'herd immunity' to the fore, as states like Bihar, Odisha have claimed that their serosurvey results indicate that they have nearly achieved herd immunity. What is herd immunity? AIIMS, New Delhi doctor Yudhyavir Singh has said Delhi might have achieved herd immunity, considering the extent of the second wave of the pandemic, PTI reported.
