Schumer says a Zika vaccine has been developed, but it needs to go through expensive clinical trials to ensure there are no side effects before distributing to the public. 

“But unfortunately because Congress hasn’t allocated the money, the trial on this vaccine is going to come to a screeching halt and we won’t have a vaccine,” Schumer said.

Schumer says he made his request in a letter to House and Senate leadership.
