DNA vaccines

DNA vaccines use a small piece of genetically engineered DNA to teach the immune system how to recognize and fight a specific virus. When injected, the DNA enters the body's cells, which then produce a protein similar to the virus. This triggers the immune system to develop antibodies and memory cells without causing illness. If exposed to the actual virus later, the body can respond quickly and effectively. DNA vaccines are considered safe, stable, and efficient, offering a promising approach for disease prevention and rapid development against emerging pathogens.
