Solution

Vaccine is nothing but dead or weakened form of organism that can act as a pathogen for a particular disease. Thus, it is introduced inn the body in the form of an antigen and antibodies are produced against it in the body. The body's immune system remembers these antibodies and they form again to fight the infection once the pathogen attacks the body again.
For example, there are vaccines against hepatitis A, measles etc.
