It's not a new virus. Just changed a bit as all virus do change time to time but the good news is the vaccine still protects according to the scientists. Fingers crossed |

The vaccines have been double blind tested on volunteers in several countries - each vaccine varies a little on the countries where testing occurred. Typically the USA, UK, Brazil and others were included this year. A small number of those vaccinated became infected but nobody was purposefully given any specific variant to infect them, all of the volunteers just went about their normal lives, where they may have come into contact with the virus, just as we randomly may do in our lives.
Much of the trial for the current approved vaccine happened outside of the UK and it completed some weeks ago.
It's possible that this new variant existed then here and in places where it was trialled but this variant is fairly new as a known problem. It's probably better to assume it's not been under trial whilst the new form was around, being cautious.
Greater analysis of the new form will better evaluate how well the vaccines should provide immunity against it. Unless there is substantial change to the specific area of the virus that is targeted by our immune response gained from the vaccine, it should retain its efficacy level.

"Does the vacine works on this new virus?they say it does but did they ever tested the vacine on people infected with the new virus?
Yes it does according to the briefing today. "
yeah I seen the briefing today but they didn't sayd they tested the vacine with people with the new string.

It's not a new virus, We are not even certain if it's a new strain.
There is a variant which seems to have the same symptoms however just seems to be more infectious. |

They say the vaccine should work on the new strain, but medics/scientists are very worried about further mutations of the virus. That is when you can run into problems with the vaccine |

I am reading a book called "One hot summer / the big stink".
This book was wrote about three of the most inspirational minds of the 19th Century. I think the title "The big stink" should have been written about 2020. I am hearing lots of statements like "more contagious strain" but by what measure? Totally fed up with this draconian / cotton wool, half in /half out approach. Tbh it's the uncertainty that winds me up. Give us the facts and let us vote! |

The definition of "more contagious" is either:
a) Can attach to and enter cells more efficiently
b) The number of viral particles required to cause disease is lower
c) Results in one individual infecting, on average, a larger number of people, compared to other variants
Or (more likely), a combination of all three.
Also factors like the ability of the virus to evade or subdue the immune system (a common virulence factor) and all sorts of other factors impact on the severity of disease. All theses factors are difficult to quantify separately because they are intertwined, hence the difficulty in saying conclusively whether the new variant is, for certain, more infectious, or whether we're observing the result of, for example, increased contact between people in schools, colleges, workplaces, shops etc and this is likely to be indoors (therefore immediately higher risk).
There's plenty of literature out there about it, mainly in specialist publications written in complex scientific language. |
