The Malaria Vaccine Implementation Programme study area in Ghana: results of a household survey prior to the introduction of the RTS,S/AS01 vaccine.
Article in Malaria journal, 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
backgroundIn 2019, the RTS,S/AS01
methodsThe baseline household survey was conducted between 25 February and 18 March 2019 in a representative sample of 6778 households across 66 districts (33 in each of the implementing and comparator areas) in Ghana. Caregivers of children aged 5-48 months were interviewed. For each child, vaccination details were transcribed from the maternal and child health record book, and we measured the mid-upper arm circumference and obtained a malaria Rapid Diagnostic Test (RDT). Survey-weighted coverage estimates were obtained using standard survey methods. Survey Poisson regression was used to estimate prevalence ratios.
resultsOverall, 7768 children were included in the study, and 21% (95% CI 18-23) tested positive for malaria parasitemia by RDT. About 87%, 95%CI (85-89) of all households owned at least one ITN, and 62%, 95%CI (59-64) of children aged 5-48 months slept under an insecticide-treated net (ITN) the night before the survey. Additionally, 22%, 95%CI (21-24) of children reported having fever in the two weeks preceding the survey; among those with reported fever, 72%, 95%CI (69-74) sought advice or treatment, 40%, 95%CI (37-44) were tested for malaria, and 42%, 95%CI (39-46) of those with fever took an antimalarial drug. Additionally, 17%, 95%CI (16-19) had a mid-upper arm circumference (MUAC) ≤ 13.5 cm, and 1%, 95%CI (0-1) had a (MUAC) ≤ 11.5 cm. The uptake of vitamin A VAS in the 6 months prior to the survey was 36%, based on routine delivery through EPI, and deworming coverage was 29%. Coverage of EPI vaccines was > 90%. Indicators in comparison and implementation areas were comparable.
conclusionsThe pilot implementation and evaluation of the RTS,S malaria vaccine in Ghana was conducted in an area with substantial malaria transmission and illness, modest health-seeking behaviour and ITN use, and good EPI vaccine coverage. This study has established the baseline comparability between implementation and comparator areas, which serves as the foundation for future feasibility assessments.
