According to indications from other nationwide sero surveillance conducted by the Indian Council of Medical Research (ICMR), the Indian population is still far from developing herd immunity against Sars-CoV-2. Union Health Minister Dr. Harsh Vardhan gave this information on Sunday. The report of the first serosurvey released in May showed the spread of coronavirus in only 0.73% of the population across the country.
The second report of the serosurvey will come soon
Responding to questions from social media users, the Health Minister said, "The second report of the soon-to-be-released CERO survey has indicated that we are still far away from developing herd immunity. Therefore, instead of being lethargic, we all should follow the rules related to Kovid-19 seriously.
What is herd immunity?
Herd immunity is indirectly a defense for a large population, causing people to develop immunity through natural or vaccine. But this is possible only when a large part of the population develops immunity or gets vaccinated after getting infected. In this program named 'Sunday Dialogue', Harsh Vardhan replied to the questions of social media users on Twitter. He said that the report of the second serosurvey will be made public soon.
Antibodies necessary for herd immunity in 60–7% of people
Harsh Vardhan said, 'ICMR's sero survey report should not create a sense of fearlessness in people, because herd immunity is usually achieved only when about 60-70 percent of the population of a country develops antibodies against the virus. Should be Since it is not yet for us. So we should know that a large population in India is very susceptible to getting infected. We need to understand the behavior of Kovid-19 right now.
What is a serosurvey?
Blood samples for serosurveys are tested for LGM (Immunoglobulin G) antibodies to determine if the infection was caused by a virus. From the end of August to the beginning of September, about 24,000 sample tests have been conducted in 70 districts of 21 states. The serosurvey is also important to know whether the disease has reached the community transmission stage.
How far away from herd immunity?
ICMR officials said that the second phase sero survey is a follow-up to the first one. The same process is repeated here which took place in May. Explain that the National Institute of Epidemiology based in Chennai, ICMR is examining the samples and supervising the results under this survey. Epidemiology experts also say that Indians are still far away from developing herd immunity.
Do not hurry for herd immunity: expert
According to Dr. Giridhar Babu, Professor at the Indian Institute of Public Health, 'As far as herd immunity is concerned, we are far from its mark. But there should be no hurry to get it. Rather, it should be done systematically so that our health care system can be prepared for the patients reached in critical condition. Like Sweden, taking no measures to reduce the transmission rate, we do not have such an option.
