A new study in mice shows that females vaccinated before pregnancy and infected with Zika virus while pregnant bear pups who show no trace of the virus. The findings offer evidence that an effective vaccine administered prior to pregnancy can protect vulnerable fetuses from Zika infection and resulting injury.

Summary:

Zika virus can cause severe brain damage in people infected before birth. A new study in mice shows that females vaccinated before pregnancy and infected with Zika virus while pregnant bear pups who show no trace of the virus. The findings offer the first evidence that an effective vaccine administered prior to pregnancy can protect vulnerable fetuses from Zika infection and resulting injury.
