Evaluating a Group B Streptococcus (GBS) vaccine in pregnancy

Volunteers wanted

We are inviting pregnant women/birthing people to participate in the BEATRIX study evaluating a Group B Streptococcus (GBS) vaccine in pregnancy.

GBS is a common type of bacteria carried by 1 in 5 pregnant women/birthing people.

GBS can cause complications during pregnancy and serious illness in babies. This maternal vaccine study could help protect babies around the world from GBS.

This study is enrolling healthy, pregnant women/birthing people who are expecting a single healthy baby. If you join the study, you will receive 1 dose of the study vaccine or a placebo when you are between 24- and 36-weeks pregnancy.

A placebo looks like the study vaccine but has no active ingredients.

If you decide to take part

  • Your health and the health of your baby will be closely monitored during the study
  • Study visits will occur throughout pregnancy and up to one year after delivery
  • Some of these visits may occur by phone or at your home
  • There is no cost to be in this study and you will be compensated for your time and travel
