This is encouraging. It appears to work against the omicron variant.<p>We're currently using the first generation of vaccines. Consider those a minimum viable product. They mostly work, need to be stored cold, have short shelf lives, don't cover enough variants, and are injection drugs.<p>The next generation of the technology is in development.
