You've heard of getting the flu vaccine in a nasal spray, and scientists are now working on a new delivery system. It goes in the nose but in gel form. Delsite Biotechnologies has developed a way to deliver the vaccine using a powder that gels on contact. The powder, that uses an aloe vera molecule, carries the flu vaccine into the nasal passages. Once it makes contact with moisture in the nose and sinus area, the powder gels and adheres to the tissue. Then, the vaccine is slowly delivered into the nasal tissues.
So, why go to a gel when you have the spray? The company says this system does not require refrigeration, so it would be easy to distribute for people to give to themselves in the case of a flu pandemic.
