Explanation:
<em>You haven't attached the text.</em>
"Vaccines" are developed in order to prevent a person from getting infected with a particular disease, thereby also preventing him to spread that disease to others.
Once the person gets a vaccine, the<em> small strains of pathogen</em> are introduced into the body and it results to an<u> immune response.</u> This will help the body know how to fight off the disease once it encounters such in the future.
