Question

how is vaccine is different from a medicine?

Answer 1

Vaccination is when a vaccine is administered to you (usually by injection). Immunisation is what happens in your body after you have the vaccination. The vaccinestimulates your immune system so that it can recognise the disease and protect you from future infection (i.e. you become immune to the infection).

Answer 2

vaccine helps in forming antibodies against a pathogen before getting infected while medicines are used to kill the pathogen when we are in infected state
