Building herd immunity may not work in tackling the COVID-19 outbreak since there isn’t yet a vaccine for SARS-CoV-2, according to Giridhar R Babu, professor and head of life course epidemiology, Public Health Foundation of India.
Herd immunity refers to vaccinating a bulk of the population to prevent them from getting infected and therefore, from transmitting the germ responsible for the infection to other people. This way, even those who cannot be vaccinated are protected.
Babu has worked with the World Health Organization for nearly six years, during which his efforts included stopping polio transmission in Karnataka and initiation of measles surveillance. He has also worked as a research associate for Multi Centre AIDS Cohort (MACS).
"Vaccinations are the safest way to practice herd immunity in a population," Babu told Moneycontrol in an interview.
