Inhalable 'aerogel' triggers immunity to COVID-19 in mice, may block transmission

An inhalable "aerogel" loaded with DNA that encodes for the SARS-CoV-2 spike protein successfully induces an immune response against COVID-19 in the lungs of mice, according to new research conducted at Pennsylvania State University. The research team said its aerogel could be used to create an inhalable vaccine that blocks SARS-CoV-2 transmission by preventing the virus from establishing an infection in the lungs.
