Amid the coronavirus pandemic, there have been talks about herd immunity. While many are unsure what it is all about, experts from the medical fraternity speak to The Free Press Journal's Kanchan Srivastava to tell us more about herd immunity.
Maharashtra medical council president Dr Shivkumar Utture, Dr Kamaxi Bhate from KEM hospital Mumbai and Dr Able Lawrence from SGPGI Lucknow in conversation with Kanchan Srivastava speak explain "What is herd immunity and can we attain herd immunity against COVID-19 by lifting the lockdown?"
For herd immunity, 2/3 populations needs to attain immunity against coronavirus either by vaccination or by infection, say experts.
Medical experts across the world have said that herd immunity occurs when people in a particular area become immune to an infectious disease that it stops it from spreading. This can be done in two ways: many people contract the disease and over time, build an immune response or if they are vaccinated against the disease.
This happens when a large section of the population becomes immune to the disease resulting in the virus spread slowing down or stopping.
In certain diseases, you are required to have a herd immunity of 80 to 95 per cent.
