Question

Why do we take vaccination? How do they work?

Answer 1

Answer:

We're protected from infectious disease by our immune system, which destroys disease-causing germs – also known as pathogens – when they invade the body. If our immune system isn't quick or strong enough to prevent pathogens taking hold, then we get ill.A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.
