Scientists at the University of Pennsylvania and the biotech firm Regeneron are investigating whether technology developed for gene therapy can be used to make a nasal spray that will prevent infection with the new coronavirus.
The idea is to use a weakened virus as a delivery truck to carry genetic instructions to cells within the nose and the throat, which will in turn create powerful antibodies to stop SARS-CoV-2 from invading our bodies.
“The advantage of our approach is that you don’t need a competent immune system for this to be effective,” James Wilson, a professor of medicine at Penn who is leading the project, told AFP.
The technology is currently being tested in an…
