Vaccines take advantage of your body’s natural ability to learn how to combat many disease-causing germs, or microbes, that attack it. Vaccines provide safe, cost-effective, and efficient means of preventing illness, disability, and death from infectious diseases.
Why Is Vaccine Research a Priority for NIAID?
Once your immune system is trained to resist a disease, you are said to be immune to it. Before vaccines, the only way to become immune to a disease was to actually get it and, with luck, survive it. This is called naturally acquired immunity. Vaccines, which provide artificially acquired immunity, are an easier and less risky way for a body to develop immunity to many diseases. Vaccines can prevent a disease from occurring in the first place, rather than attempt to cure it after the fact. Learn more about the benefits of vaccines and vaccine research.
How Is NIAID Addressing This Important Area of Study?
NIAID conducts and supports basic research in areas such as infectious diseases, microbiology, and immunology to generate the knowledge essential for developing safe and effective vaccines. NIAID also supports clinical research on vaccines against bacterial, viral, and parasitic microbes in people of all ages and risk categories. Vaccine safety is an integral component of all NIAID vaccine research and development. Read more about the NIAID role in vaccine research.
