What Travel Vaccines are and how do they function?

A vaccine is a certain type of medicine injected in the body that trains the body’s immune system against a disease it has not come into contact with before. Vaccination helps in prevention, rather than treatment of a disease once you have caught it. Travel vaccines are designed to provide immunity against diseases found in other parts of the world.
