Waning levels of measles antibodies with increasing time post-vaccination suggests that measles susceptibility is potentially increasing in Korea. This trend may be related to limitations of vaccine-induced immunity in the absence of natural boosting by the wild virus, compared to naturally acquired immunity triggered by measles infection. This study provides an important view into the current measles herd immunity in Korea.


Measles-specific antibodies wane in the absence of boosting by the wild-type virus.

The number of potential measles-susceptible individuals progressively accumulates.

Vaccine-induced immunity is less effective than naturally acquired immunity.
