Effect of early life antibiotic use on serologic responses to oral rotavirus vaccine in the MAL-ED birth cohort study.
Article in Vaccine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundOral rotavirus vaccine efficacy is lower in low- and middle-income countries (LMICs) than in high-income countries. The degree to which antibiotic use impacts rotavirus vaccine immunogenicity in LMICs is unknown. Using data from a multisite prospective birth cohort study of malnutrition and enteric disease, MAL-ED, we examined the effect of early life antibiotic use on the immune response to rotavirus vaccine.
methodsWe assessed whether antibiotic use from birth up to 7 days following rotavirus vaccine series completion was associated with rotavirus seropositivity at 7 months of age in Brazil, Peru, and South Africa using a modified Poisson regression. We then used parametric g-computation to estimate the impact of hypothetical interventions that treated all children and alternatively prevented inappropriate antibiotic treatments on seropositivity.
resultsOf 537 children, 178 (33%) received at least one antibiotic course during the exposure window. Probability of seropositivity was 40% higher among children who had at least one course of antibiotics compared with those with no antibiotic exposure (PR: 1.40, 95% CI: 1.04, 1.89). There was no significant difference by the number of antibiotic courses received or total duration of antibiotics. Treating all children with antibiotics would be associated with a 19% (95% CI: 18%, 21%) absolute increase in seropositivity at 7 months. In contrast, removing inappropriate antibiotics would result in a 4% absolute reduction (95% CI: -5%, -2%) in seropositivity.
conclusionsEarly life antibiotic use was associated with increased seropositivity. However, a hypothetical intervention to remove inappropriate antibiotics would have little effect on overall seropositivity. Further investigation into the underlying mechanisms of antibiotic use on the infant gut microbiome and immune response are needed.
