Answer 2

Vaccines are made up of weak microorganisms.

• As per the definition,' A vaccine 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 weakened or killed forms of the microbe, its toxins, or one of its surface proteins.
• When a disease-causing foreign agent enters our body our immune system remembers it and takes necessary actions against it.
• Vaccination is the safest and most common way to gain immunity against a bacteria or virus that your body has yet to encounter.
