Will there be any side effects after receiving a flu shot with the PharmaJet “needle-free” Injector?

Vaccines are capable of causing side effects regardless of the method of delivery, needle or needle-free.3

In a clinical study, the PharmaJet Needle-free injections had slightly higher local reactions e.g. soreness and bruising, than needle and syringe, but these were mild to moderate in intensity, well-tolerated and mostly resolved within three days. This did not impact the patient’s choice for needle-free as evidenced by 93% indicating they would choose to receive a needle-free flu shot again4 Check the vaccine labeling for a description of possible local reactions.
