Experimental flu vaccine bypasses needles

An experimental flu vaccine that blasts tiny particles into the skin instead of using a needle appears to be safe in people, biotech firm PowderMed Ltd. said on Wednesday.


The British-based company said it would move into bigger tests of its vaccine, which uses DNA from the flu virus to stimulate immunity.

Writing in the journal Vaccine, PowderMed scientists said the vaccine stimulated an immune response in all 36 volunteers.
