That’s different from the Covid-19 vaccines made using messenger RNA carried in fatty particles called lipids. “Then that is given to people, and they make an immune response that’s very much focused just on the spike – and I would say, the hallmark of our vaccine is it gives a very strong immune response with very few side effects, and the dose is very small and the vaccine can be stored with normal refrigerated temperatures.” We never touch the coronavirus itself,” he added. We put it in a particle – basically, like a soap bubble – and it’s the size of the virus,” Glenn said. “The whole idea of the vaccine is to show the immune system something that looks, tastes and acts like a virus, with the exception that it doesn’t make you sick.

Syringes wand vials of the Pfizer-BioNTech Covid-19 vaccine are prepared to be administered to front-line health care workers under an emergency use authorization at a drive up vaccination site from Renown Health in Reno, Nevada on December 17, 2020. Yet the way various coronavirus vaccines do that can vary. Getting the immune system to recognize and “remember” those spike proteins is key in how a vaccine helps protect against Covid-19. These knob-shaped structures are what the virus uses to connect to human cells, causing infection. These spikes form large protrusions, giving coronaviruses the appearance of wearing crowns. When the sequence published online, scientists around the world quickly identified the SARS-CoV-2 virus, which causes Covid-19, as a coronavirus because it has what are called “spike proteins” on its surface. How Novavax’s vaccine works – using moth cells “The sequence was published on the Internet, the genetic sequence for the virus – and we could see it was a coronavirus. “It occurred to us that this just might be ‘SARS 2,’ ” Glenn said. They wondered whether that outbreak could be due to another version or recurrence of the coronavirus that causes severe acute respiratory syndrome or SARS. In January of last year, Glenn and his colleagues were closely watching an unusual cluster of pneumonia reported in China. Novavax CEO: 'Burden's on us' to convince FDA on UK data
