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…
Study published in Heliyon Journal shows superiority of needle-free injection over needle and syringe for poliovirus vaccine fIPV campaigns
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.
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.
ONdrug DELIVERY publishes PharmaJet Study that links Needle-free Injection to Increasing Workplace Flu Shot Compliance
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.
Clinical Study published in Vaccine supports reduced dose vaccination with the PharmaJet Tropis Needle-free Injection System
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.
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.
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.
