Flu kills around 3,000 Australians over 50 every year, yet only 41 per cent of us were vaccinated last year. Now US researchers have developed a painless patch that has shown to be a safe and effective as a regular flu vaccination – without the painful prick.
How does it work?
The patches use around 100 microneedles to deliver the vaccine. These are pressed into the skin on the wrist until a snapping sound is heard and then left for 20 minutes during which the microneedles containing the vaccine dissolve into the skin.
And the results are promising.
Taking the sting out of vaccination
In the trial of 100 people, 96 per cent of participants who used the patches reported no pain – compared to just 82 per cent of those who had a needle – with 70 per cent saying they would prefer to use the patches over a shot in the future.
Unlike regular vaccines, the patches don’t need to be refrigerated and can be easily thrown away like a Band-Aid when you’re done – unlike a needle.
While the patches still need to go through larger clinical trials, we think it’s a smart idea.
Users can apply the patch themselves, saving on a trip to the doctor or pharmacy – ideal for the frail and elderly.
It’s welcome news too for those of us with a fear of needles. Every year, I think I should get a flu shot – and decide not to so I can avoid the jab. Bring on the Band-Aids.
