2019

Authors: O’Brien S, Sharland M, Zaoutis T

Published in: AMR CONTROL 2019-2020; online edition

Abstract It is time to prioritize children’s needs in the context of antimicrobial resistance (AMR). Children, especially babies and young infants, are particularly vulnerable to the rise in drug-resistant infection and need treatments that are adapted to their specific needs. Yet, there are almost no clinical trials looking into children’s antibiotics.
