Ethnic bioweapon

An ethnic bioweapon, also known as a race-specific bioweapon, is a type of bioweapon that is designed to harm people of specific races or ethnicities, while leaving other people unharmed.

Such weapons usually work by targeting specific segments of DNA or protein that are present only in people of a specific ethnicity, and attacking their cells whilst leaving those without such specific segments unharmed. Therefore, the weapon is only effective if the targets and attackers are of different ethnic or racial makeup. For such a situation, ethnic bioweapons negate the disadvantage of most bioweapons (the fact that they kill their own creators just as they kill their enemies) by making their creators immune to the weapon.
