Vaccines and Disease

What is a Vaccine?

"Vaccination is a simple, safe, and effective way of protecting you against harmful diseases, before you come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger. Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease."

Some US government health websites and data are not currently available or the information may be contested by the professional medical community. There is no perfect alternative to government databases, but some non-governmental organizations have their own datasets, which can be useful. This article contains a list of alternative sources of health data.
