raditional vaccines contain weak or inactive forms of viruses or bacteria. They stimulate your body’s immune system to respond to the disease-causing substance, which protects you if you’re exposed to it in the future. More recently, scientists have developed vaccines that instead use genetic material from viruses or bacteria, such as RNA or DNA, to help your body mount this defense.mRNA (messenger RNA) vaccines are already in use against the virus that causes COVID-19. Scientists are now looking to use a DNA vaccine as another option to fight COVID-19 and other infectious diseases.

What Is a DNA Vaccine?

DNA (deoxyribonucleic acid) is genetic material found inside the cells of every living organism. You could think of it as an instruction booklet for how cells reproduce themselves in your body.

Since the 1990s, experts have been researching how they could use DNA to create vaccines. These are called DNA vaccines.

How Does the DNA Vaccine Work?

When you get a DNA vaccine, your cells translate the gene particle from the virus or bacteria into a protein that your body recognizes as a foreign element. Your immune system then creates antibodies that fight these particular proteins, stop them from attaching to your cells, and eventually destroy them. The vaccines teach your body to recognize these proteins to prevent future infections.
