Answer 2

A vaccine is a type of medicine that prepares the immune system of the body to battle a disease that it has never seen before.

Explanation:

• To understand how vaccinations function, people must first understand how the immune system operates. Antigens are substances found on harmful viruses and bacteria's surfaces.
• Antigens induce antibodies, which are proteins, to be produced by the immune system. Antibodies bind to antigens, causing the infection to die or become incapacitated.
• Antigens are found on the surfaces of pathogens. Only an antibody that can bind to the pathogen's antigens will be able to destroy or disable it. Only if the immune system has already encountered the antigen will antibodies form.
• Vaccines safely expose the body to viruses, allowing the immune system to create antibodies that bind to their antigens. If the immune system comes into contact with a disease-causing pathogen again in the future, it will be able to fight it.
