Talk on vaccination and immunity – July 10, 2021


For a bacterial infection, we take antibiotics that help destroy the bacteria. Why don’t we have a similar antiviral to get rid of a viral infection? Why does vaccination involve getting jabbed two or more times? When our bodies have a built-in natural immune system, why then the struggle against corona virus? For answers to questions such as these, sign up for அறி (aRi) this coming weekend.
