In India, a study found that the rate of antibodies to the novel coronavirus infection (Corona 19) among residents of the Delhi National Capital Territory (NCT, Delhi) exceeded 56%. Even before the massive COVID-19 vaccination was carried out, the antibody retention rate was close to 60-70%, the level of collective immunity.

India’s second largest cumulative number of confirmed cases in the world
Group immunity was investigated before vaccination
According to local media such as The Hindu and NDTV, Delhi performed serum tests on 28,000 Delhi residents from the 15th to the 23rd of last month. Delhi state health authorities surveyed 11 districts, including the capital city of New Delhi, for different age groups and found that the average antibody retention rate was 56.13%.
In addition, the district with the lowest antibody retention rate of residents recorded 49.09% and the district with the highest recorded 62.18%, showing no significant gap between regions.
The cumulative number of confirmed cases officially counted by Delhi state authorities is 635,000, and the cumulative death toll is about 1,900. Delhi has a population of more than 20 million, and according to the test results, the actual number of infected people is about 11 million, which is 18 times the number of official confirmed cases.
Delhi has conducted a total of 5 serum tests since July of last year. Antibody retention rose from 23% in July to 29.1% in August, then 25.1% in September and 25.5% in October.
Delhi Minister of Health Satiendar Jain said on the 2nd (local time), “Deli, with 20 million people, is heading for collective immunity considering the last results. ”
New daily confirmed cases, from 8,000 in November last year, to a recent drop of 100
In fact, the number of new confirmed cases in Delhi, where there were 8,000 new confirmed cases a day in November of last year, fell to 1,000 from the end of last year. In recent years, it has decreased significantly to 100 people a day.
Indian local media also cited experts and reported that the Indian capital is moving toward mass immunity. However, an official from Indian health authorities told India Express, “Corona 19 is a new disease. We must not change our quarantine strategy based on collective immunity,” he stressed the need for quarantine, such as vaccination and social distancing.
India started vaccinating against Corona 19 on the 16th of last month. According to Bloomberg Vaccine Tracker, the number of vaccinations in India is about 3.95 million every three days.
