- No needle? Really? REALLY! The vaccine is expelled in less than half a second through a tiny hole, creating a fluid stream that does all the work.
- How is this different from a needle? Needle-free is different in many ways. Unlike a needle injection that deposits all of the vaccine in a pool near the tip of the needle deep in the tissue, needle-free leaves a small trail of vaccine in the skin. Subsequently, the itchiness and redness, caused by the body's immune defenses being activated by the vaccine, may be more visible than with needle delivery.
- Will I experience any other side effects? If you take blood thinners or if you bruise easily, needle-free may result in temporary bruising at the injection site.
- Is this pain-free? Patients report a preference for needle-free versus a needle. Many report feeling the pressure of the injection or a short stinging sensation. Many report no pain at all.
- Is vaccine delivered with needle-free as effective as getting the it with a needle? Yes. Hundreds of millions of doses of vaccine have been delivered in the US and around the world using similar technology.
