Cross-sectional study evaluates measles antibody levels in adults, suggesting gaps in immunity and need for public health measures.

To evaluate antibody levels specific to measles in Mexican adults and identify trends related to vaccination and infection history.
Conducted a cross-sectional seroepidemiological study with 302 blood donors aged 18–70 years.
Collected demographic, clinical, and vaccination data through structured interviews.
Measured serum anti-measles-virus IgG levels using ELISA and analyzed based on age, sex, and vaccination history.
Applied multivariate linear models to identify factors associated with antibody levels.
67.2% of participants were seropositive for anti-measles IgG with a geometric mean concentration of 270.43 mIU/mL.
A positive correlation was found between age and antibody levels (rs = 0.161, p = 0.005).
Older individuals (pre-1970) had higher GMCs (1096.63 mIU/mL) compared to younger cohorts.
Natural infection history was linked to higher antibody levels (GMC: 428.38 vs. 257.24 mIU/mL; p = 0.051).
Historical vaccination strategy was identified as the primary factor influencing antibody levels.

Muñóz-Valle et al. (2026) studied this question.
