What do vaccines do?

Vaccine imitate germs

Vaccines imitate germs and in doing so, train your body to recognise and fight real germs if and when you are exposed to them.

Immune response is triggered

Your immune system is triggered to respond, helping you build immunity against the disease.

Extra training needed

Sometimes, the immune system needs more than one training session to learn how to fight the disease effectively. In these cases, a few doses of the vaccine may be necessary over a period of time. To ensure that you are protected, it is important to get vaccinated as per the recommended timings and not delay it
