NCT ID NCT04588428
First seen Jan 27, 2026 · Last updated Jun 23, 2026 · Updated 21 times
Summary
This Phase 2 trial tested a new DNA vaccine called INO-4700 in 192 healthy adults to see if it is safe and can trigger an immune response against MERS, a serious coronavirus. The vaccine is given as a shot under the skin followed by a quick electric pulse to help cells take up the DNA. The study looked at side effects and measured antibodies and T-cell responses.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
INO-4700 (DNA vaccine given under the skin followed by a mild electric pulse to boost uptake)
What this could lead to
If successful, this could lead to a vaccine that protects people from MERS, a serious respiratory virus.
What could go wrong
This is a Phase 2 trial with only 192 healthy volunteers, so it is still early. The vaccine may not produce strong enough immunity or could cause side effects like injection site reactions.
