30. Explain how vaccination fools our immune system.
Answers
Answer:
Vaccination is a simple, safe, and effective way of protecting people against harmful diseases, before they come into contact with them. It uses your body’s natural defenses to build resistance to specific infections and makes your immune system stronger.
Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.
Most vaccines are given by an injection, but some are given orally (by mouth) or sprayed into the nose.
Explanation:
pls mark me as a brainlist bro
The vaccine is made up of deactivated or dead pathogens, when it enters our body then our immune system thinks that they are living pathogens that will cause diseases. now immune system starts releasing all the material required for fighting from that pathogens.
Hence the immune system gets fooled
It is in very simple language, I hope it helps
