Securing long-term immunity: The possible necessity of supplementary measles vaccination.
Article in BMC infectious diseases, 2024. 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
backgroundThe global initiative to eliminate measles, spearheaded by the World Health Organization, has yet to achieve its intended goals. In Turkey, despite robust vaccination strategies, recent increases in measles cases have been attributed to vaccine hesitancy and irregular migration. This study evaluates measles serology within a pediatric population to determine the impact of vaccination regimens on immunity.
methodsA retrospective study at Ankara Bilkent City Hospital analyzed serum measles IgG levels in children aged 1-18 years from January 2020 to August 2023. Exclusions were applied for individuals with positive IgM results, incomplete vaccinations, and immunocompromised conditions. Patients were categorized based on their M-M-R
resultsOf the 686 children, 30.2% received a single dose, and 69.8% received two doses of the MMR vaccine. Overall, 70.7% exhibited positive IgG levels. No significant differences were found in IgG levels between those who received one dose and those who received two doses. However, a decline in IgG levels was observed with age, particularly notable in adolescents aged 14-18 years.
conclusionThe study reveals seropositivity rates lower than expected, highlighting challenges in achieving WHO targets. This suggests a potential need for booster doses during adolescence to maintain protective antibody levels. The findings emphasize the importance of continued surveillance and research to adapt vaccination strategies effectively and prevent measles outbreaks, particularly considering the decline in antibody levels and diverse vaccination histories across populations.
