About Vaccines

What are vaccines and how do they work?

Vaccines, vaccinations, immunizations, or shots; no matter what you may call them, they are a critical part of your travel preparations and health wellness.

Your immune system keeps you healthy and fights off infectious diseases. Antibodies are an important part of the immune system. They recognize and help destroy invaders, such as viruses or bacteria. If you have antibodies for an infectious disease, it means your body can often defend itself against that disease or infection.

Antibodies are produced in two ways: by being exposed to the disease itself, or by getting a vaccine. A vaccine triggers the immune system to make antibodies to help protect against disease. Vaccinating against certain diseases helps protect more than just yourself. It is important to note that some adults are not fully vaccinated. Also the protection provided by some childhood vaccines fades over time.  (Resource ACP)
