What exactly IS a vaccine?

San Francisco CA

Description

In essence, a vaccine is a small dose of the target virus. This small exposure to the target virus gives your body an opportunity to create a defense known as antibodies to the target virus. As this occurs, you body builds a safe and effective defense against the virus dramatically reducing your chance of getting a full blown case of this virus in the future. Pretty clever huh? Vaccines are not new. They have been around for hundreds of years. Vaccines are literally a more efficient way of allowing your body an opportunity to defend itself. Why would anyone not want that??? Why would anyone be afraid of a vaccine???
