Here is a post from Marcus from another BB which helps explain the choice of Pharmajet is much more about simple avoiding needle phobia it is about improving the immune response.
CEO, PharmaJet, commented: " Our Needle-free Systems are proven to improve the immune response for multiple DNA and RNA vaccines as well as being widely used to deliver vaccines for diseases such as influenza, measles and polio."
Our needle-free technology features a precise and consistent method of delivery, which helps to maximize target gene expression in the human body,” said Ron Lowy, Chairman and Chief Executive Officer, PharmaJet Inc. “In addition, it offers benefits over the alternative of electroporation delivery.”
Needle-free injectors are known to augment DNA vaccine response, possibly by increased dispersion of injectate or through tissue disruption that increases immunogenicity. The GMT after split-dose needle-free delivery of VRC5283 was six times higher than that after single -dose delivery via needle and syringe.
the greatest effects seen were with VRC5283 given in split doses via needle-free injection in the VRC 320 trial. One hundred percent (100%) of participants who received the vaccine by needle-free injection in split doses had detectable antibody responses and had neutralizing antibody and T-cell responses of the greatest magnitude.
