“…Thank you for giving us the opportunity to comment on the letter by Farah Seedat and John Marshall 1 from the National Screening Committee Evidence Team, in response to our mini commentary 2 . We can confirm that in our GBS3 trial (ISRCTN49639731) for hospitals allocated to the intervention arm (universal group B streptococcus [GBS] testing in late pregnancy or in labour), the protocol recommends that women with certain risk factors for GBS such as a preterm birth or a previous baby with early‐onset GBS (RCOG 2017 guideline 3 ) are offered either intrapartum antibiotic prophylaxis (IAP) or testing for GBS, with the offer of IAP if the test result is positive.…”
