• An experimental vaccine can help a person’s body fight an aggressive form of brain tumor
  
  
• The vaccine is made personally for each patient, using genetic material drawn from their own tumor
  
  
• It activated the immune system against brain tumors in human, dog and mouse studies
  

One of the most impressive results was how quickly the injectable vaccine turns the immune system against a brain tumor, said senior researcher Dr. Elias Sayour, a pediatric oncologist with University of Florida Health who pioneered the new vaccine.

In a first-ever human clinical trial with four adult patients, the vaccine prompted a quick and apparently effective immune attack on cancer.

“In less than 48 hours, we could see these tumors shifting from what we refer to as ‘cold’ -- immune cold, very few immune cells, very silenced immune response -- to ‘hot,’ very active immune response,” Sayour said in a university news release.
