Vaccines have been around for hundreds of years, with the first vaccine trials dating back to the 1930’s. A vaccine is used to stimulate the body’s immune response against diseases and is typically administered through injections. The aim of a vaccine is to immunize the vaccinated individual from a specific disease should they come in contact with it. Basically, it makes your body familiar with a disease before you get it, that way it is better prepared to fight that disease if it enters your body.
Vaccines can all be administered at different life stages and in different doses. In most cases, it is still possible to get sick with what you are vaccinated against; however, you will likely not experience the seriousness of the disease. For certain deadly diseases, vaccines can prevent them completely, saving millions of lives over the years.
There are certain vaccines which protect against harmful or deadly diseases, that are highly recommended by the Centers for Disease Control and Prevention (CDC) to receive. Most vaccines are required for school, jobs or other programs, to keep large populations safe and prevent widespread disease. Vaccines are usually required when traveling outside of the U.S. as well, so be sure to check guidelines before you travel.
