doctor stephen griffin has spent his career studying viruses and how to fight them.oes the coronavirus infect us? the virus is present in droplets, and then that gets into the airway in your mouth and in your nose, and infects cells in our bodies. then as the infection gets more progressively expanded within your body, it will start to spread further down. it gets in, hijacks the cells because the virus can not replicate on its own. the whole point of a parasite like a virus is to get in, get out and spread. the best way to beat a virus is to stop it spreading from person to person. and the best way to do that is with a vaccine. a vaccine should make us immune. if we vaccinate people enough, then the virus just doesn't have any where else to go, and so therefore you can eventually eliminate it. around the world, more than 100 teams are racing against the clock to create a vaccine. one of the most promising is being developed here in oxford. the process normally takes years. the team he hopes to produce a vaccine in super quick time. we need to go really, really fast.
