Vaccination Faq.


  Why do we 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 unimmunized individuals (Table 1). Prior to the development of vaccines, these diseases disabled or killed millions of children. Many people living in developed countries today do not appreciate the value of vaccines 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 immunized.

Are there different types of vaccines?

There are two major categories of vaccines.

The first category of vaccine is made from live viruses that have been "attenuated" or weakened so that they usually do not cause the disease (Table 2). In some cases, the vaccine itself does cause the disease. Usually, the disease caused by the vaccine is milder than the natural disease.

The second category of vaccine, inactivated vaccine, is produced by growing the bacterium or virus in culture and then inactivating it (killing it) by using heat or chemicals (Table 3). These vaccines cannot cause the disease but allow the body to develop immunity. While these vaccines are safer, they do not produce protection as good as that from the live vaccines. These vaccines require multiple doses and often require periodic supplementation. PLSEASE VISIT THIS WEBSITE OF MEDICINE.NET.COM
