Then, just after 1:00 p.m., medics were called back to the school for at least one more student who had a bad reaction to the drug.
A school district source tells Action News that a total of four students have been taken to the hospital. It is unknown when the fourth student was transported.
School district officials say all four students are recovering, and are doing fine. The district had no further comment.
