True, because your body needs to encounter the pathogen at least once in order to create the antibodies.

Antibodies kill off any antigen that enters the body.

Antibodies are only made when you are given a vaccination for specific antigens.

Antibodies bind to specific antigens to flag for destruction.

Antibodies are part of an external defense mechanism.

Allow B cells to make antibodies for any type of antigen the body comes in contact with.

Triggers the body to make memory cells for specific pathogens.

They are substances prepared from killed or weakened pathogens.

Always allows the body to resist an infectious disease any time it comes into contact with it.

Killer T cells

Supporter T cells

B Cell

The body will not be able to fight off the pathogen quickly, because it knows how to get into the body easier.

The body's immune system will react the same was as it did during the first exposure.

The body can only be exposed to a pathogen a second time if you do not have a vaccine.

The body will know how to fight off the pathogen quickly, because memory cells have been created after the first encounter.

T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.

T cells only make memory cells, and B cells only make antigens

T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.

T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
