    A coronavirus disease 2019 (COVID-19) vaccine can prevent you from getting COVID-19 or from becoming seriously ill or dying due to COVID-19. Different types of vaccines work by causing the immune system to create antibodies to fight COVID-19.

    The mRNA vaccine gives your cells instructions for how to make the S protein found on the surface of the virus, which causes your body to create antibodies that will fight the virus if you later become infected with it. Both Pfizer and Moderna use this type of vaccine.

    In a vector vaccine, material from the virus is placed in a modified version of another virus, giving your cells instructions to make copies of S proteins; once displayed on cell surfaces, your immune system creates antibodies and defensive white blood cells that will fight off infection if exposed later. Janssen/Johnson & Johnson uses this type of...

    This type contains only parts that best stimulate immunity; harmless S proteins are included so when recognized by immune system it creates antibodies and defensive white blood cells that will fight off infection if exposed later.
