Why B is correct Can you explain with lots of detail Vacci

Vaccination can protect from a pathogen by increasing the number of a. different types of receptors that recognize the pathogen b. cells with receptors specific for the pathogen c antigens present on immune cells d. phagocytic cells that can destroy the pathogen Explain your answer here:

Solution

Answer: B. cells with receptors specific for the pathogen

Explanation:

Vaccine contains harmless version of pathogen(inactive). When a vaccine is injected, white blood cells (receptor cells) are stimulated to produce antiobodies. These antibodies bind to pathogens and kill them. As the vaccine is inactive, the receptor cells will not react with inactive form of pathogen present in the vaccine.The receptor cell left over and will be ready to fight the pathogen when the respective pathogen entered the body in future.

eople can be immunised against a pathogen through vaccination. Different vaccines are needed for different pathogens
