Vaccine technology

Vaccine technology involves teaching your immune system how to recognize and fight harmful germs like viruses or bacteria. Modern vaccines often use tiny parts of the germ, such as proteins or genetic material, to stimulate an immune response without causing illness. For example, mRNA vaccines deliver instructions to produce a specific viral protein, prompting immunity. Traditional vaccines may contain weakened or inactivated germs. Once vaccinated, your immune system remembers these invaders, so if exposed later, it can quickly respond and prevent illness. This technology has been crucial in controlling many infectious diseases and continues to evolve rapidly.
