Easier to produce COVID vaccine shows promise in trials; nasal spray vaccine booster works in mice

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. New COVID-19 vaccine could be manufactured like flu shots. A COVID-19 vaccine that can be produced locally in low- and middle-income countries is yielding promising results in early clinical trials, researchers say. The NDV-HXP-S vaccine, developed at Icahn School of Medicine at Mount Sinai in New York City, uses an engineered version of the harmless Newcastle disease virus studded with coronavirus spike proteins to teach the immune system to recognize and attack the virus that causes COVID.
