American scientists successfully developed a new technology in immunization and they have developed the microneedles to delver painless immunization.

Sean Sullivan and other experts from Emory University conducted experiments on mice and have proved that instead of a shot, people in future could be immunized through a “stick-on” skin patch containing tiny microneedles.

The microneedle developed was less than 1 mm in length. It dissolves into the skin and is small enough that they don’t draw blood or cause pain. If the patches are found ok, the immunization in humans will become easier by putting the patch on the skin.

Sullivan told that so many annoyances with the standard vaccination process that could go away.
Because the patch appeared to work using less vaccine than in a typical shot, the discovery has the potential to reduce the amount of vaccine that needs to be produced, which could alleviate shortages in case of pandemic flu, other experts said.
