Clinical Study Published in The Lancet Supports Flu Shots Administered with PharmaJet’s Needle-Free Injector

The Lancet recently published a study that demonstrates that the delivery of an influenza vaccine with the PharmaJet Needle-Free Jet injector compares favorably to a traditional needle and syringe delivery.
