Correction to: Nature Microbiology,, published online 17 February 2020

In the version of the Article originally published, the following text was mistakenly omitted from the end of the abstract: “Trial Registration: Westmead Hospital Human Research Ethics Committee HREC/17/WMEAD/275; NCT03395769; Clinical Trials Notification (Australian Therapeutic Goods Association): CT-2018-CTN-02372-1.” This has now been corrected.
