this seems like it might work.

These special llama antibodies, called “nanobodies,” are much smaller than human antibodies and many times more effective at neutralizing the SARS-CoV-2 virus. They’re also much more stable….

“Nature is our best inventor,” said senior author Yi Shi, Ph.D., assistant professor of cell biology at Pitt.Shi’s nanobodies can sit at room temperature for six weeks and tolerate being fashioned into an inhalable mist to deliver antiviral therapy directly into the lungs where they’re most needed. Since SARS-CoV-2 is a respiratory virus, the nanobodies could find and latch onto it in the respiratory system, before it even has a chance to do damage.
