Dear moms-to-be, don’t fear Zika virus. A new vaccine can protect your unborn child

The Zika virus causes a mild, flu-like illness in most people but it’s especially dangerous for pregnant women.

The Zika virus has got a lot of people worried. Many efforts are being made by researchers to minimise the transmission and effects of the virus. Pregnant women need to be especially careful as their healths and habits affect the child. Now, researchers have found that immunising women with a Zika vaccine during pregnancy can protect the transmission of virus from mother to her baby in utero. Researchers from the University of Texas’s medical branch at Galveston in the US found that the Zika vaccine can protect unborn child against infection and birth defects.

Zika virus causes a mild, flu-like illness in most people, but to pregnant women the dangers are potentially much worse. The virus can reduce fetal growth, cause microcephaly, an abnormally small head associated with brain damage, and even trigger a miscarriage. According to new research, immunising female mice with a Zika vaccine can protect their developing fetus from infection and birth defects during pregnancy.

Senior study author Pei-Yong Shi said that his team was the first to show that two different potential vaccines given to a mother and prevent the Zika virus from infecting the fetus during pregnancy in a mouse model. Based on these data, we believe that evaluating the vaccines’ ability to prevent birth defects in humans are warranted, Shi added. Female mice were vaccinated against Zika with one of the two developing vaccines prior to becoming pregnant and then exposed to the virus during their pregnancies.
