Adherence to infection prevention measures and vaccine uptake among pregnant women and new mothers in Sweden during the COVID-19 pandemic.
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 was a global public health crisis that affected everyone, including pregnant women and new mothers. Previous research suggests this population adhered well to infection prevention measures, though vaccine uptake was limited due to safety concerns. Sweden’s largely voluntary and less restrictive pandemic response provided a unique context to study adherence and vaccination patterns. This study aimed to examine adherence to infection prevention measures and COVID-19 vaccination among pregnant women, new mothers, and their families.
methodsWe conducted a longitudinal study using data from the prospective population-based NorthPop Birth Cohort Study in Sweden. Repeated questionnaires were distributed between June 2020 and December 2021, enabling assessment of self-reported adherence to infection prevention measures and COVID-19 vaccination uptake. Descriptive statistics were applied, and differences were analysed using Pearson’s chi-square test and independent-samples t-tests. Sensitivity analyses were performed to examine differences in adherence between participants who were pregnant during the pandemic and postpartum participants, and associations with vaccination were examined using univariable logistic regression.
resultsPregnant women and new mothers reported high adherence to infection prevention measures, peaking in December 2020 and declining thereafter for most behaviours. Compared with postpartum participants, women who were pregnant during the pandemic were less likely to limit social contacts (OR = 0.69, 95% CI: 0.49–0.97) and to stay home when experiencing cold symptoms (OR = 0.68, 95% CI: 0.49–0.93). Vaccine uptake was high (94.7%) among all participants. Participants with at least a university degree were more likely to be vaccinated than those with lower educational level (OR = 3.04, 95% CI: 1.87–4.92), and the likelihood of vaccination increased by 9% with each additional year of age (OR = 1.09, 95% CI: 1.03–1.15).
conclusionsTrust in public authorities and the healthcare system, together with a strong sense of collective responsibility, may partly explain the high adherence to recommendations and COVID-19 vaccine uptake among pregnant women and new mothers during the COVID-19 pandemic in Sweden. Sociodemographic differences in vaccine uptake highlight the need for targeted communication and support. These findings provide insights relevant for future pandemic preparedness and maternal health policy across Europe.
