Azithromycin for Child Survival in Niger: Mortality and Resistance Trial

The MORDOR trial found that biannual distribution of azithromycin to children 1-59 months old reduced child mortality. The World Health Organization (WHO) released conditional guidelines for this intervention, which include targeting azithromycin distributions to children 1-11 months of age in high mortality settings.Targeting treatment to children 1-11 months old could reduce antimicrobial resistance by limiting antibiotic distributions while treating children at the highest mortality risk. However, this targeted intervention has not yet been tested. The AVENIR mortality/resistance trial aims to assess the efficacy of age-based targeting of biannual azithromycin distribution on mortality as well as determine the impact of age-based targeting on antimicrobial resistance.
