The first two vaccines against the Novell coronavirus could be administered toe Americans before Christmas.

That's according to the U.

S.

Health Secretary Alex.

As our it comes as Madonna has filed for both us and you regulator regulatory approval of its coronavirus vaccine so that it can be recommended for widespread use.

Regulators will look a trial data for the M R N a vaccine and decide if it is safe and effective enough for emergency use authorization.

Clinical studies suggest the jab is more than 94% effective at protecting people from becoming ill with covert 19.

Pfizer, who's vaccine works in a similar way, has already filed for approval from the U.

S.

Food and Drug Administration.

Well, let's go straight, Thio, the BBC's online health reporter, Michelle Roberts.

Michelle, good to see you.

So this is another bit of good news about the vaccine it is.

So we're hearing about these various vaccines that are getting edging closer to this end goal of actually becoming available to more people.

So at the moment they're still just in trials.

This Madonna one, we've got latest data from those trials from 30,000 people, and it appears to be very effective.

94% of those trials also included elderly people, the types of people that you really need to think about protecting eso.

There seems to be good news, but obviously now regulators need to look at that data and check that they're happy that it's safe and effective enough to give it the go ahead.

Alexa's ours talked about rolling it out in the United States by Christmas or before Christmas.

There is a big question about distribution and transportation because there are so many countries in the world with huge amounts of vulnerable people that need to get access to these kinds of vaccines.

I mean, certainly the World Health Organization is concerned that possibly richer nations will be at the front of the queue, leaving developing world and coronations to play catch up with this.

A lot of stocks that are available at the moment have been brought up by the US, the UK, various European countries, Um but some are committed to a kovacs this group, this global group, to get vaccines out to the developing world, so that should hopefully help, obviously developing actual physical stocks of the vaccine takes time.

There are lots of doses that are ready to go in the glass files at the moment, but production will need to ramp up to get to the billions that we need for the world.

Indeed, very much so.

And I suppose there is also this thing around complacency where people think are every week we're hearing that more companies air coming up with these vaccines.

It's important, not Thio.

Relax too much at the moment.

Obviously, we've had Thanksgiving.

We've got Christmas coming up where people might be socializing mawr mixing MAWR.

The virus hasn't gone away, and we don't have these vaccines to actually give to the masses yet.

So the message really from the health experts is just hold your horses.

Be careful.

Keep doing all the social distancing.

But hopefully soon we will have lots of stock to start giving to people.

It's quite extraordinary, Michelle, when you think about this, because actually the pace in which these companies are going and scientists are going to develop these vaccines when actually some of these things can take decades, its breakneck speed.

We've never seen anything like this before on the technologies that they're using is really exciting as well.

So the Madonna and Pfizer jabs use M R N A.

It's a brand new type of technology on bond.

If that does work, it would mean that you could look a using the same type of technology for other diseases that we've not been able to crack in the past.

Eso It is a very exciting time.

Very much so.

Michelle, thanks so much for bringing us up to speed.
