Measles serostatus among health care workers in a university clinic in Hungary in 2024.
Article in Preventive medicine reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Healthcare workers (HCWs) face elevated risk of measles exposure and may facilitate nosocomial spread. Despite early (1969) national vaccine introduction and high (>99%) coverage, sporadic cases and small outbreaks tend to occur in Hungary pointing to possible immunity gaps. We evaluated quantitative measles IgG levels among HCWs in a Hungarian university clinic to assess immunity against measles morbillivirus. Methods: Between July and November 2024, sera from 2541 HCWs were tested by quantitative ELISA. Antibody titres were categorized into four groups, with >200 mIU/mL considered protective immunity. IgG levels were analyzed by age, sex, and vaccination schedules. Results: Overall, 78.83% had protective antibody levels, while 21.17% were below the protective threshold, including 13.81% with IgG <150 mIU/mL. Unvaccinated group (born before 1968) provided the highest antibody titres exceeding vaccinated groups. Significant differences in serum titres detected between individuals received different vaccine regiments by age groups. Newer combinations, such as MMR-II/Priorix, elicited higher antibody levels compared to old combinations. HCWs aged 39-50 years showed the highest (32-38%) susceptibility. Conclusions: A substantial proportion of HCWs have low level of measles antibodies, especially in specific age cohorts. Targeted screening and revaccination are recommended to close immunity gaps and prevent nosocomial transmission.
