Vaccination FAQs

Why do people need vaccines? What is immunization? What is immunity?

Vaccines are medications that boost our ability to fight off certain diseases. Many of the vaccine-preventable diseases are highly contagious and even fatal in non-immunized individuals (Table 1). Prior to the development of vaccines, these diseases disabled or killed millions of people. Many people living in developed countries today do not appreciate the value of immunizations because the successful use of vaccines has almost eradicated many of these diseases. These diseases are still dangerous and can kill people who are not adequately protected from them.
