Covid-19 antibodies have been detected in 67% of the population of India, according to a new survey, indicating how widely the virus spread through communities during the second wave.
India’s fourth national sero-survey, which examines the prevalence of Covid-19 antibodies either through infection or vaccination, found that 67.6% of the population of more than 1.3 billion has coronavirus antibodies.
The survey also demonstrated the slow pace of India’s vaccination programme. Of those surveyed, 62.2% had not been vaccinated, 24.8% had taken one dose and 13% were fully vaccinated.
The survey result marks a significant rise from the last such survey which was conducted in December and January and found that just 24% of the population had antibodies. This recent survey was carried out in the final weeks of June and beginning of July, just as the second wave had abated, interviewing almost 29,000 people across India.
“The findings clearly show that there is a ray of hope but there is no room for complacency,” said Balram Bhargava, director general of the Indian Council for Medical Research.
