Rubella titers, which indicate immunity to the rubella virus, can remain detectable in the body for many years after vaccination or infection. However, the exact duration can vary from person to person. Generally, after vaccination, immunity is considered to last for at least 10 to 20 years, but some individuals may retain protective titers for life. Regular testing may be recommended for certain populations, such as pregnant women or healthcare workers, to ensure continued immunity.
