Needle-free Injection – Eradicating Diseases to Improve Global Health

Needle-free Injection technology has evolved significantly over the last 50 years and is now accepted in many routine immunization settings as a safe and effective vaccine delivery method. Disposable syringe jet injectors are now being used for the delivery of vaccines to eradicate polio, MMR, and influenza, and are showing promising results in vaccine clinical…

Clinical Study published in The Lancet shows significantly higher immune response with Needle-free injection

The Lancet recently published a study that demonstrates that the delivery of a Zika virus vaccine with the PharmaJet Stratis Needle-free Jet injector resulted in a higher immune response as compared with administration via needle and syringe. Needle-free injectors are known to augment DNA vaccine response, possibly by increased dispersion of injectate or through tissue…

Clinical study published in Vaccine cites superiority of two fractional doses administered intradermally to one full intramuscular dose. Expands use of PharmaJet Tropis Needle-free Injector

The polio eradication endgame strategic plan calls for the sequential removal of Sabin poliovirus serotypes from the trivalent oral poliovirus vaccine (tOPV), starting with type 2, and the introduction of ≥1 dose of inactivated poliovirus vaccine (IPV), to maintain an immunity base against poliovirus type 2.

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. This is the first definitive non-inferiority study to measure the immune responses to all three influenza viruses induced after administration of a seasonal flu vaccine by a jet injection device as compared to a needle and syringe.

Survey of Satisfaction with Needle-Free Administration of Afluria®, Influenza Vaccine (AMCP poster)

In the fall of 2014, nearly 400 individuals were surveyed about their experience receiving a PharmaJet Stratis® Needle-Free flu shot during the University of Tennessee Flu Shot day. Subjects were overwhelmingly accepting and the data suggests that needle-free vaccination through jet injection may be widely accepted in the general adult population and expand vaccination rates.
