Haven't read the study in depth, but results look promising.
They looked at over 20,000 women who got the pertussis vaccine during pregnancy and found :
"There was no evidence of an increased risk of stillbirth in the 14 days immediately after vaccination (incidence rate ratio 0.69, 95% confidence interval 0.23 to 1.62) or later in pregnancy (0.85, 0.44 to 1.61) compared with historical national rates. Compared with a matched historical cohort of unvaccinated pregnant women, there was no evidence that vaccination accelerated the time to delivery (hazard ratio 1.00, 0.97 to 1.02). Furthermore, there was no evidence of an increased risk of stillbirth, maternal or neonatal death, pre-eclampsia or eclampsia, haemorrhage, fetal distress, uterine rupture, placenta or vasa praevia, caesarean delivery, low birth weight, or neonatal renal failure, all serious events that can occur naturally in pregnancy.
Conclusion: In women given pertussis vaccination in the third trimester, there is no evidence of an increased risk of any of an extensive predefined list of adverse events related to pregnancy. "
And because we all know people are going to accuse the study of being pharma compromised:
"Funding: This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.
All authors have completed the ICMJE uniform disclosure form at http://www.icmje.org/coi_disclosure.pdf
and declare: no support from any organisation for the submitted; no financial relationships with any organisations that might have an interest in the submitted work in the previous three years, no other relationships or activities that could appear to have influenced the submitted work."
So for discussion, what do you think of the study and results?
