Zika Vaccines And Pregnant Women: Here’s What Ethics Experts Say

Avril Lavigne once sang, “Tell me, why’d you have to go and make things so complicated?” Since that was from her 2002 album Let Go, chances are she was not singing to the Zika virus…unless she knew something that we didn’t at the time. But nowadays her Complicated song could certainly apply to nearly everything about the Zika virus…including the Zika vaccines that are currently under development.

I’ve previously written about how the Zika virus has turned out to be a trickier than initially thought. But what’s so complicated about Zika vaccines besides the fact that vaccine development in general is complicated? Well, the biggest risk of Zika infection is to pregnant women, because the virus can cause devastating birth defects in the fetus. Therefore, pregnant women could certainly use a Zika vaccine for protection, but….  Don’t we usually avoid testing vaccines or other medications on pregnant women, because of potential risk to the fetus and the woman and the many changes a body undergoes while pregnant? A pregnant woman is not the same as a non-pregnant woman in many ways physiologically. A two-weeks pregnant woman is not the same as 2-months pregnant woman. One pregnant woman is not the same as another pregnant woman. These physiologic changes and ethical issues make Zika vaccine development and testing more…complicated, as Lavigne sang, “Uh huh, uh huh. That’s the way it is.” Time to call in the ethics experts.

That’s what the Wellcome Trust did in supporting the formation of the “Ethics Working Group on Zika Virus Research & Pregnancy.”
