Correct answer: B). The flu vaccine
The flu vaccine is a type of vaccine that protects the body against the flu. It develops antibodies after two weeks of vaccination. These antibodies provide protection against influenza viruses. The flu vaccine reduces the risk of flu illnesses, hospitalization, and flu-related death. It only protects the body against influenza, not any other illnesses.
