Solution

When a weakened or dead pathogen is injected in our body system it causes an immune response accordingly, after which antibodies are formed against such pathogen. When a pathogen attacks the body again, the body produces many antibodies which may vary according to infection, meaning large number of antibodies are produced in severe infection and lower number of antibodies are produced in mild infection.
