Is vaccine delivery with “needle-free” as effective as getting it with a needle?

Yes. According to the Advisory Committee on Immunization Practices (ACIP), “Immune responses generated by jet injectors…are usually equivalent to, and occasionally greater than, immune responses induced by needle injections”.1

Additionally, a clinical study demonstrated that delivery of a flu vaccine with the PharmaJet Needle-free Injector compared favorably to traditional needle and syringe delivery.2
