What are Vaccines
When are they employed
Objective of mass utilization
A vaccine is designed to provide you immunity to a disease. It is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from a weakened or killed form of the microbe, and its toxins. They are made in the laboratory utilising (viruses) killed or weakened versions of the disease-causing germ (antigens). They are usually made annually to adapt to the new versions and are easy to replicate.
A vaccine stimulates your immune system to produce antibodies, exactly like it would if your body was exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first, unless you have already been exposed.
