What is rubella immunity?

Rubella immunity refers to the body's ability to resist infection from the rubella virus, which causes the illness known as German measles. This immunity can be acquired through vaccination, typically the MMR (measles, mumps, and rubella) vaccine, or through previous infection with the virus. Individuals with rubella immunity are protected from contracting the disease and are less likely to transmit it, which is particularly important for protecting vulnerable populations, such as pregnant women, who are at risk for severe complications. Testing for rubella immunity is often done in prenatal care to ensure the health of both the mother and the developing fetus.
