The so-called Brazil variant may evade up to 61% of the immunity brought about after people overcome older versions of the coronavirus, research suggests.
There are six known cases of the Brazil variant in the UK, one of which health officials are still trying to trace after they left their contact details off their coronavirus test registration card.
The emergence of new variants raises questions as to whether they will spread more readily, cause more serious complications or even evade a former coronavirus patient's natural immunity, as well as that brought about by the long-awaited vaccination programme.
To learn more, scientists from around the world screened virus samples collected in Brazil, with results suggesting its variant may evade between 25% and 61% of the immunity brought about after an individual overcomes a different version of the coronavirus.
While it may sound alarming, Professor Sharon Peacock – director of the COVID-19 Genomics UK Consortium – stressed the results should be interpreted with a "note of caution", with there being limited evidence the Brazil variant will "threaten our vaccine strategy or effectiveness".
The results are preliminary and yet to be published in a peer-reviewed journal.
Viral mutations are entirely expected, with the majority having a neutral effect.
Concerns were raised, however, when coronavirus cases spiked in Manaus – the largest city in the Amazon – despite incidences already being high in that region.
Genetic sequencing of virus samples collected between November 2020 and January 2021 revealed a "variant of concern" had emerged.
Now known as the "Brazil variant", it has 17 mutations, three of which affect the virus' spike protein, potentially aiding entry into cells.
The spike protein binds to a cell's so-called ACE2 receptor, allowing it to invade the body. The protein is also a target for many vaccines.

ACCORDING TO STUDIES:

Using a “dynamic model” made up of genetic and death data, the global scientists estimate the Brazil variant is 1.4 to 2.2 times more transmissible than previously circulating versions of the coronavirus.
The Brazil variant may also be able to evade 25% to 61% of “protective immunity elicited by previous infection” with other versions of the virus, the results suggest.
To put this into context, “if 100 people were infected, 25 to 61 are susceptible” to the Brazil variant, according to study author Dr Nuno Faria, from Imperial College London.

Dr Susan Hopkins, from Public Health England, added: “This variant that emerged in Manaus in Brazil is really quite similar to the [variant] from South Africa and they have a number of mutations that are suggested to increase transmissibility.
“Manaus in particular reported a number of individuals were reinfected with this variant, and therefore that suggests having had prior immunity from primary infection wasn’t enough to reduce infection and transmission, and that may also impact on the vaccine.”
Some believe vaccine effectiveness may be reduced, but is highly unlikely to be eliminated altogether.
Dr Jeffrey Barrett, who genetically sequences coronavirus samples at the Wellcome Sanger Institute, also told the Today programme: “I think there is some laboratory-based evidence it [the Brazil variant] is partially less neutralised by vaccines.
“I don’t think we know how much of a difference that will make in the real world.
“We certainly don’t think it will be completely able to escape vaccination.”
Oh dear! Texas just opened up. Push the triple scary super duper South American variants!!!
Biden needs to get them all up here for further study.
The only thing we have to fear is fear itself.
And the government knows how to frighten sheeple.
Wait. Isn’t it raciss to name a coronahoax-virus after its country of origin?
Yes, sounds like an ideal candidate for Biden to bring in unscreened illegals who might be carrying this variant along with whatever else and then bus them into Texas, Mississippi and where ever else states are opening up.
Come on, man! What’s one more crisis?
RE: Isn’t it raciss to name a coronahoax-virus after its country of origin?
UK Variant - OK
South African Variant - OK
Brazilian variant - OK
Wuhan Virus - racist
Gotta keep the Panic Train moving
I have yet another dumb question: Isn’t this kind of thing why there is no cure for the common cold?
(And no, I’m not saying the China Virus is just a cold)
RE: Isn’t this kind of thing why there is no cure for the common cold?
See here:
https://www.health.com/condition/infectious-diseases/coronavirus/coronavirus-symptoms-vs-cold
Four common human coronaviruses cause 15-30% of common colds (Most often, however, the common cold is caused by rhinoviruses, per the CDC). Their peak season is also winter—aka, the same time as influenza.
However, what we are dealing with currently is a new or novel coronavirus, “meaning that it mutated in some way and became more deadly and more transmissible.
‘Rona will never go away if it’s up to half of society.
Shouldn’t we all just kill ourselves now, just to make sure we don’t get killed by a variant?

Coronavirus PING!
They must give it a different name. It shall therefore be called . . .
BOLSONARO’S FAULT!!!
/sarc
These variants mean that a corona vax will simply become an annual shot like the flu shot: just combine the three variants that you deem are mostly likely to affect people in a particular winter season and start “shooting” ‘em up!
And this is different from other corona viruses in exactly what ways?
Maybe because they were never infected and only presumed to be
The article says that this Brazilian variant is 1.4 to 2.2 times more transmissible than previously circulating versions of the coronavirus. It also evades the immune system of past infected patients, meaning it re-infects those whose immune system recognized the original Covind-19 virus. This also implies that current vaccines available for the Coronavirus could possibly be useless ( we don’t know that for sure ).
