Antitoxins and antivenoms are agents that can neutralize the effects of toxins or venoms.
Antitoxins can be made by the same species or other organisms. Their blood is then extracted, purified and injected into affected humans or animals. Antitoxins are used to treat or prevent diseases such as tetanus, which is caused by biological toxins.
Antivenom is produced by injecting a small (safe) amount of that particular venom into an animal and once that animal makes antibodies against the venom, the blood is drawn, purified and used to treat bites, etc. by the venomous organism (for example snake bites).
