Including Pregnant Women In Clinical Trials Could Be Key To Developing Effective Zika Vaccine

The Hill: To find an effective Zika vaccine, we must include pregnant women in the trials

“…The pursuit of a truly effective Zika virus vaccine … is handicapped by a long-standing clinical practice: the exclusion of pregnant women from drug development and vaccine trials. The main reason for this is ethical: Why expose a growing fetus, or a mother-to-be, to unknown risks in an experimental setting? … As commendable as this practice is, we argue it is more ethical to include pregnant women in certain clinical trials than to exclude them. … When contagions like Zika disproportionately affect pregnant women, excluding moms-to-be may end up harming them and their babies more than it helps. … To decide the most effective Zika virus vaccine based on tests among non-pregnant women with different body chemistry may produce a vaccine not potent enough for expectant mothers. … By contrast, the addition of expectant mothers as subjects in vaccine and drug-development trials holds out an intriguing and desirable possibility: a tailored therapy for different trimesters of pregnancy that caters specifically to the health and well-being of both mother and child” (11/12).
