Washington University develops COVID-19 saliva test

Washington University School of Medicine in St. Louis has developed a saliva-based test for COVID-19 that is faster and easier than the swab tests currently in use. The test could help simplify and expand the availability of COVID-19 diagnostic testing across broad populations.

Nasal vaccine against COVID-19 prevents infection in mice

Washington University School of Medicine scientists have developed a vaccine that targets the SARS-CoV-2 virus, can be given in one dose via the nose and is effective in preventing infection in mice susceptible to the novel coronavirus.

Experimental COVID-19 vaccine prevents severe disease in mice

Researchers at Washington University School of Medicine in St. Louis have created a COVID-19 vaccine candidate from a replicating virus. This experimental vaccine has proven effective at preventing pneumonia in mice.

Lab-made virus mimics COVID-19 virus

To help efforts to find drugs and vaccines for COVID-19, researchers at Washington University School of Medicine developed a hybrid virus that will enable more scientists to enter the fight against the pandemic. The researchers genetically modified a mild virus.
