Estimating the impact of the RTS,S/AS01 malaria vaccine in Benin: A mathematical modelling study.

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
Malaria constitutes a major public health burden in sub-Saharan Africa. It remains a key health concern and the leading cause of death in children under five in Benin. Since October 2021, the World Health Organization has recommended the use of malaria vaccines for the prevention of Plasmodium falciparum malaria in children living in malaria endemic areas, prioritizing areas of moderate and high transmission in sub-Saharan Africa. However, with the exception of Ghana, there is a scarcity of studies modelling the potential impact of the RTS,S/AS01 vaccine in the context of West Africa. A compartmental mathematical model was developed to estimate clinical and severe malaria cases averted in children under five with the primary series of the RTS,S/AS01 malaria vaccine in Benin. Over a period of 10 years, scenarios involving vaccine introduction at different coverage levels alongside the use of long-lasting insecticidal nets were modelled to assess the impact of the RTS,S/AS01 vaccine on malaria transmission. The combination of childhood malaria vaccination at a coverage similar to that of the third dose of diphtheria, tetanus, and pertussis (DTP3) vaccine, along with the current use of nets, is projected to result in a 40% reduction in malaria clinical cases and deaths among children under five years old, compared to using nets alone, from 2025 to 2034. However, if the introduction of a malaria vaccine has the unintended consequence of decreased net use, cumulative benefits may be offset. A 1.5-fold decrease in the use of nets is projected to result in an increase in malaria burden. This modelling exercise concludes that childhood vaccination is expected to avert clinical and severe cases of malaria and is an additional tool to advance malaria control efforts in Benin but potential unintended consequences of a reduction in net usage may reduce these gains.
