The first coronavirus vaccine can prevent more than 90% of people from getting Covid-19, a preliminary analysis shows.

The developers - Pfizer and BioNTech - described it as a "great day for science and humanity".

Their vaccine has been tested on 43,500 people in six countries and no safety concerns have been raised.

The companies plan to apply for emergency approval to use the vaccine by the end of the month.

There are around a dozen vaccines that have reached the final stages of testing, but this is the first to show any results.

It uses a completely experimental approach - that involves injecting part of the virus's genetic code - in order to train the immune system.

Two doses are needed, three weeks apart, and the pharmaceutical companies say people are protected a week after the second dose.

It has been trialled in the US, Germany, Brazil, Argentina, South Africa and Turkey.

Pfizer believes it will be able to supply 50 million doses by the end of this year and around 1.3 billion by the end of 2021.

I hope so, even that seems like forever away but an end date is more than welcomed too

I wonder how long it would take to distribute on such a scale that’s it effective for the population, there’s probably an article somewhere but does anybody know?

as per my post above it is suggested all over 50s could be vaccinated by Easter if they want it of course

it will also be made available abroad as it has to be a worldwide programme to be effective

Thought this too. However I’m guessing if enough people are vaccinated herd immunity will do the rest of the work?

Yeah, that’s what I meant you still have to give it a large % of the population for herd immunity so I wonder how long that’d take

Rustic bauble · 09-11-2020, 01:12 PM

Yes...its great news Cherie.

...I was chatting to someone last week who’s working on the vaccine...and the indication given was that it’ll start to be being used before Christmas with a completion of Spring next year...I presume that all means ‘hopefully’...that’s the thought atm....

fast panel made zone

bots · 09-11-2020, 12:05 PM

it really depends if it provides long term protection

The big question mark now of course is how long antibodies ask, and if that's short, does the T-cell response mean it's still effective (covid with us forever but not more worrying than any other mild illness).

But it's impossible to know that for a year+ really. E.g. flu strain immunity often lasts 2 or 3 years in healthy people (which is why you don't get flu every single year).

Did you know that the flu vaccine is much more effective if you have had plenty sleep before you get it? Anti body production is much higher if rested .... crazy little facts

My daughter got the flu vax for the first time in years this year and promptly got sick (minor sniffles and sneezing) 2 days later
