A brand new start-up firm will collaborate with the pharmaceutical trade to check and market the “Bubble Gun” know-how, he mentioned.

Common phobia

It may nonetheless take 1-3 years for the strategy to be out there to most of the people, relying on the progress of analysis and regulatory points.

Roughly one in 5 Dutch individuals are afraid of needles, mentioned Henk Schenk, who presents remedy to assist these struggling acutely. “Phobia of needles is more common than you might think. People are ashamed to admit it.”
