PARIS: Vaccines delivered via a painless, throw-away ***** could one day eliminate the need for needle-and-syringe flu injections, researchers said Wednesday after completing a preliminary trial.
Equipped with micro-needles, the *****es vaccinated against influenza just as effectively as a standard flu jab, they reported in the medical journal The Lancet.
"This bandage-strip sized ***** of dissolvable needles can transform how we get vaccinated," said Roderic Pettigrew, director of the US National Institute of Biomedical Imaging and Bioengineering, which funded the study.
The new tech**logy can be self-administered and stored without refrigeration, making it significantly cheaper that traditional vaccines. "It holds the promise for delivering other vaccines in the future," Pettigrew added.
A hundred tiny needles -- just long e**ugh to penetrate the skin -- embedded in each ***** dissolve within minutes when exposed to moisture from the body. Adhesive holds the ***** close the skin while the vaccine is released, and can be peeled away after 20 minutes and discarded.
In phase I clinical trials, researchers from Emory University in Georgia and the Georgia Institute of Tech**logy randomly divided 100 adults into four groups.
Three received the micro-needle *****es: one delivered by a healthcare provider; one self-administered; and the third -- delivered by a nurse -- a placebo without any active ingredients.
The fourth group received a classic flu jab with a syringe. All the active flu vaccines worked equally well for at least six months, regardless of whether they were delivered by professionals or the patient, or whether they were administered by a syringe or a micro-needle.
The manufacturing cost for the *****es is expected to be about the same as for pre-filled syringes. But the ***** is expected to be cheaper because it can be sent through the mail and self-administered.
In addition, it is stable for a year at 40 degrees Celsius (104 degrees Fahrenheit), and does **t require refrigeration, the researchers said. "These advantages could reduce the cost of the flu vaccine and potentially increase coverage," said lead author Nadine Rouphael, an associate professor at Emory. "Our findings **w need confirming in larger trials."
