O The antigens produced by a vaccine only fight specific antibodies.

Answer 1

The antibodies produced by a vaccine only fight specific antigens.

Step-by-step explanation:

Antibodies only bind to specific antigen during an immune reaction. The introduction of foreign substance in the body stimulate the B-cells to produce antibodies that fight against infections. Only specific antibodies are produced following antigen presenting cells that bind to antigens. They capture and display the antigens to the antibodies.
