How does the Covid vaccine work? After how many days from vaccination does the immunity level increase?
05 Jun, 2021 | 07:29A vaccine is a dead or alive attenuated virus, which when given in a required dose, produces a mild infection, triggering the body to produce antibodies. When a person is infected with corona virus, the antibodies produced will neutralise the virus. It will take 6-8 weeks from the second dose for immunity levels to increase.
