antibodies

Infection-fighting molecules

Antibodies are proteins produced by the immune system to identify and neutralize foreign substances like bacteria and viruses.

Each antibody targets a specific invader, binding to it and marking it for destruction by other immune cells.

Vaccines work by prompting the body to produce antibodies before actual infection occurs: She tested positive for antibodies after recovering from COVID.
