Trypanophobics can rest a little easier today. The Financial Times reports that British scientists have successfully injected an experimental vaccine into mice using a needle-free syringe. “The test is the latest in a series of efforts by drug and medical device companies in recent years to find the holy grail of a needle-free syringe,” writes Andrew Jack.
The research offers hope to the legions of people suffering from trypanophobia, the fear of needles, but, more importantly, could have a significant impact on safety and low-cost distribution of vaccines around the world, he adds. It notably opens up the possibility of delivering live vaccines globally without the need for an uninterrupted cold chain during distribution.
Researchers at Kings College London used a microneedle technology developed by US-based Theraject to immunize mice with a freeze-dried vaccine. The test reportedly shows this vaccine to be as effective as the conventional version injected by a traditional needle.
