Final answer:
Cholera is a bacterial infection caused by Vibrio cholerae. Vaccination provides protection by stimulating the immune system. The vaccine contains weakened bacteria that help the body develop immunity.
Step-by-step explanation:
Cholera is a bacterial infection of the small intestine caused by the Vibrio cholerae bacterium. The infection is typically spread through contaminated water or food. Vaccination provides protection against cholera by stimulating the production of antibodies and eliciting an immune response. The cholera vaccine is made up of a weakened form of the bacteria that causes cholera, which helps the body develop immunity to the disease. If a person is re-infected with cholera, their body will produce an even greater attack on the bacteria because of the immune response established by the vaccine.
