Vaccines
Biology · Secondary 3 · Medium · Vaccines
A person is injected with an inactivated form of a bacterial pathogen as a vaccine. How does this vaccination make the person immune to future infections by the same pathogen?
- The inactivated pathogen stays in the blood and directly kills future pathogens.
- The vaccine teaches red blood cells to engulf and digest the pathogen.
- The vaccine causes white blood cells to form memory cells that respond quickly on reinfection.
- The vaccine permanently removes all pathogens from the body.
