bivalent
Having two valences
Bivalent means having two values, valences, or components.
In chemistry, a bivalent atom can form two chemical bonds.
In genetics, bivalent describes a pair of homologous chromosomes joined during cell division.
The term gained wider use during COVID-19 vaccination campaigns, where bivalent boosters targeted two viral strains: The bivalent vaccine covers both the original and Omicron variants.
