Impact of different MMR vaccination strategies on mumps incidence in Jiangsu, China: A 20-year interrupted time series analysis based on 180,000 cases.

BACKGROUND Although China upgraded its mumps vaccine schedule to two doses, quantitative evaluations of real-world, population-level effects remain limited. This study systematically evaluated the immediate and long-term impacts of 1-dose and 2-dose measles-mumps-rubella (MMR) vaccination strategies on mumps incidence...

Maternal rubella immunity gaps in the vaccine era: a seroepidemiological study of pregnant women in Jiangsu, China

Background Rubella elimination has substantially reduced virus circulation in China, but the changing pattern of immunity among women entering reproductive age remains unclear. We assessed the contemporary rubella immunity profile among pregnant women in Jiangsu Province. Methods We conducted a cross-sectional serologi...

Waning of vaccine-induced measles antibodies and population immunity gaps in the post-elimination era: a multicenter seroepidemiological study in China

High MCV coverage does not necessarily ensure sustained population immunity in the post-elimination era, and waning humoral immunity, delayed vaccination, and heterogeneous vaccination histories contribute to residual susceptibility, highlighting the need for immunity-based surveillance and targeted interventions.
