The Director of the Allergy, Immunology and Cell Biology Unit of Sri Jayewardenepura University, Dr. Chandima Jeewandara has published a note on how Sri Lanka’s could achieve herd immunity
“WHO supports achieving ‘herd immunity’ through vaccination, not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.”
“Attempts to reach ‘herd immunity’ through exposing people to a virus are scientifically problematic and unethical.”
“The proportion of the population that must be vaccinated against COVID-19 to begin inducing herd immunity is not known.In SL the proportion who are fully immune is below 25 %” He said.
Herd immunity’, also known as ‘population immunity’, is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection. (NewsWire)
