Vaccine response

Vaccine response is the way your immune system reacts to a vaccine. When vaccinated, your body recognizes the vaccine's harmless parts as foreign and triggers an immune response, mainly by producing antibodies and activating immune cells. These defenses "remember" the invader, so if exposed to the actual virus later, your body can quickly respond and protect you from illness. The strength and duration of this response can vary among individuals, but vaccines are designed to stimulate immunity effectively, reducing your risk of severe disease and helping control the spread of infections.
