Effects of climate change on vaccine storage and cold chain logistics: a qualitative study in Ogun State, Nigeria.
Article in BMJ global health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionClimate change remains a global challenge posing a significant risk to the vaccine cold chain system logistics. It threatens vaccine potency due to inadequate storage facilities and ineffective vaccine distribution mechanisms, which are mostly affected by unpredictable environmental conditions. In Nigeria, this situation is worsened by unreliable electric power supply, frequently interrupted alternative power sources, poorly trained cold chain personnel, and inefficient management procedures. These factors contribute to low immunisation coverage rates and high disease burdens. Hence, there is a need to assess the effect of climate change on cold chain system logistics.
methodParticipants were cold chain officers across vaccine cold stores in Ogun State, Southwestern Nigeria. Data were collected via a 35-item semistructured in-depth interview guide. The effect of climate change on vaccine storage and cold chain logistics efficiency in Ogun State, Nigeria, was assessed. Data were manually and thematically analysed using the constructivist variants of the grounded theory methodology. Ethical approval and participants' informed consent were obtained.
resultParticipants perceived that increasing ambient temperature variability constrained cold chain performance, resulting in equipment deterioration or damage. The vaccine distribution mechanism is mostly interrupted by difficult transportation systems caused by unpredictable weather changes. Policies are required around prompt replacement of damaged resources, equipment, continuous training of skilled workers, monitoring and surveillance system improvement.
conclusionClimate change significantly affected the efficiency of the cold chain system. Relevant policy implementation was highlighted as an essential step towards alleviating its effects.
