  • a vaccine has been shown to be more than 90% effective in preventing covert 19.

  • That's good news, right?

  • But it's sadly, doesn't mean we can get the vaccine tomorrow.

  • This is a preliminary analysis from a Phase three trial on more evidence is needed about how safe and effective this vaccine is on.

  • Then regulators need to be convinced that it could meet quality standards before it can be given to more people before we get too carried away.

  • We really have to be careful about safety and scale around the vaccine.

  • So whilst we could go with confidence, I don't think we're seeing any return to normal by Christmas.

  • But the companies behind the vaccine that's fighter and Bio n tek.

  • They're going to apply for emergency approval to use the vaccine by the end of November.

  • We'll do our best.

  • We've been working day and night.

  • The clock never stops in our labs or offices, so we'll keep on with that momentum.

  • This vaccine will need to be given in two doses around three weeks apart, but storing it is going to be a big challenge.

  • It needs to be kept in ultra cold conditions at around minus 80 degrees Celsius.

  • That's a big challenge, but the companies believe they can supply 50 million doses by the end of this year on around 1.3 billion by the end of 2021.

  • It's important to say this is not the only covert 19 vaccine currently in development there, around a dozen at the same stage of testing on we could have others soon.

  • There's a kind of tendency that, well, when we get excited about these vaccines, is to think about vaccines as a sort of silver bullet on this cannot replace just the time and tested methods off track and trace monitoring the outbreak, changing our behavior so extremely exciting, very hopeful.

  • But let's not take our eye off the ball of the very basics of how we respond to health crisis.
