IgG antibodies are core components that combat infection.

Vaccines induce the production of antibodies, and IgG antibodies are a key to achieving long-term immunity. Antibodies are not only endogenous pathogen-fighting proteins, but these are also used therapeutically to treat many diseases and conditions.
