ST. LOUIS - A breakthrough against Zika could come from St. Louis University, but first, researchers need volunteers.
St. Louis University is getting ready to test a Zika vaccine and it needs about 90 volunteers.
To take part, you must be between the ages of 18 and 49.
The volunteers get an inactivated virus, so they won't contract Zika.
Researchers will follow them for a year, watching to see if they develop antibodies that can fight the mosquito-born virus.
