A special protein your body makes when something foreign gets in — a virus, a bacterium, or another bit that should not be there. Antibodies stick to that thing and help your immune system find it and break it down. After an illness or a vaccine, some of those antibodies stay, which is why you may fight the same more easily later. A blood test can look for them to see if you have met a disease before. Though actually, the “body” here is not your arms and legs; English copied German Antikörper, where “body” means a substance. People mix this with antibiotic: one you make inside you; the other is a drug you take.
From the word’s history
From anti- + body, a calque of German Antikörper.
anti- 加 body，仿譯德文 Antikörper。
組成From anti- (against) + body, a calque of German Antikörper. Here body means a substance, not your physical body.
