bstractWe determined anti-rubella and anti-measles immunoglobulin G (IgG) in 7- to 19-year-old children and adolescents with vaccine only-induced immunity of Córdoba, Argentina, during a 6-month period over 2021?2022. Of the 180 individuals studied, 92.2% and 88.3% were positive for anti-measles and anti-rubella IgG, respectively. No significant differences were found comparing anti-rubella IgG concentrations (p = 0.144) and anti-measles IgG concentrations (p = 0.105) of individuals classified by age, but anti-measles IgG and anti-rubella IgG levels were significantly higher among female individuals compared with males (p = 0.031 and p = 0.036, respectively). Female subjects in the younger age group had higher concentrations of anti-rubella IgG as well (p = 0.020), even when anti-measles IgG concentrations did not differ among female age-subgroups (p = 0.187). In contrast, age subgroups of male individuals did not
