  • Vaccinations
    • they involve injecting small amounts of dead or inactive pathogens into the body
    • these pathogens have antigens on their surface
    • the antigens cause your white blood cells to produce antibodies to attack the pathogens
    • if your infected with the same pathogen later, your white blood cells quickly produces lots of antibodies
    • these antibodies kill the pathogen so you dont become ill
