Here's an idea whose time has come: A flu shot that doesn't require an actual shot.
For the first time, researchers have tested a flu vaccine patch(疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection(注射) with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized(免疫的) against the flu.
Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses "microneedles". These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your finger. Yet they're big enough to hold vaccine for three types of flu.
None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.
The biggest beneficiaries could be people in low and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less, is easier to transport, doesn't require refrigeration, can be self-administered and doesn't cause waste of needles—are even better.
"Microneedle Patches have the potential to become ideal candidates for vaccination programs," wrote Katja Hoschler and Maria Zambon of Public Health England.
