NEET BIOLOGY

Detailed explanation-1: -Once the antigen-specific antibodies are produced, they work with the rest of the immune system to destroy the pathogen and stop the disease.

Detailed explanation-2: -How do vaccines work? Vaccines help your immune system fight infections faster and more effectively. When you get a vaccine, it sparks your immune response, helping your body fight off and remember the germ so it can attack it if the germ ever invades again.

Detailed explanation-3: -Vaccines introduce your body to one or more proteins from a virus. This prompts it to make B cells, which produce antibodies against a specific virus. Vaccines are a safe and effective way to protect yourself from infectious diseases.

Detailed explanation-4: -An antigen specifically induces the production of antibodies which can bind to it and neutralise it. While most vaccines work by inducing B lymphocytes to produce antibodies (see below), activation of T-cells-another type of immune system cell that helps protect against disease-is also important for some vaccines.

Detailed explanation-5: -To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, mRNA vaccines use mRNA created in a laboratory to teach our cells how to make a protein-or even just a piece of a protein-that triggers an immune response inside our bodies.
