COVID-19-related disruptions and measles vaccination uptake among children attending urban health centers in Guelmim, Morocco: a cross-sectional study.
Article in BMC public health, 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
backgroundThe COVID-19 pandemic disrupted routine immunization services and may have widened measles immunity gaps. Morocco has experienced a widespread measles outbreak since late 2023. This study assessed the association between COVID-19-related disruptions and measles vaccination uptake among children in Guelmim, Morocco, and described additional informational and access barriers.
methodsA descriptive cross-sectional study was conducted from March to May 2025 in three urban public health centers in Guelmim. Using an interviewer-administered questionnaire, data were collected from 350 mothers of children aged 0-59 months. Descriptive statistics and Pearson's chi-square tests were used to examine associations between child measles vaccination status and COVID-19-related, informational, and access-related factors.
resultsOnly 44.29% of children were reported as vaccinated against measles. Lower uptake was significantly associated with delaying child vaccination during COVID-19 (27.27% vaccinated vs. 69.61% among those reporting no delay; p < 0.001), missing a measles dose during the pandemic (28.64% vs. 67.96%; p < 0.001), insufficient vaccine information (28.19% vs. 73.98%; p < 0.001), lack of trust in vaccines offered by the public health system (28.29% vs. 68.92%; p < 0.001), difficulty accessing vaccination services (35.88% vs. 69.32%; p < 0.001), and lack of information on post-pandemic vaccination dates (25.00% vs. 68.83%; p < 0.001). Receipt of a measles catch-up dose was strongly associated with vaccination uptake (82.79% among those receiving catch-up; p < 0.001).
conclusionsIn this urban sample, measles vaccination uptake was low and was associated with both COVID-19-related service disruptions and broader informational, trust, and access barriers. Strengthening catch-up activities, service communication, and trust-building strategies may help close immunity gaps in similar settings.
