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…

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…

Administration of intradermal fractional dose of inactivated poliovirus vaccine (fIPV) has proven to be safe and immunogenic; however, intradermal injection using needle and syringe is technically difficult and requires trained personnel.
Details
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.

ONdrugDELIVERY publishes PharmaJet Study
Offering needle-free technology in a workplace influenza immunization program has the potential to help address an unmet need for increasing workplace health immunization rates.
A randomized controlled trial was conducted in Cuba to determine immune responses after one fractional dose (0.1mL or 1/5 the dose size) of inactivated poliovirus vaccine using the PharmaJet Tropis jet Injector, as compared to a full dose (0.5mL) with traditional needle and syringe intradermal technique.
Details
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.

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.
DetailsAfluria is an inactivated (virus is not alive) influenza vaccine used for immunization against influenza disease caused by influenza virus subtypes A and B present in the vaccine.
