It carries a mutation that might make the virus get previous immunity developed from earlier model of the bug.

Researchers from the Oswaldo Cruz Basis, a science institute in Rio de Janeiro, have warned that mutations on the brand new variant may enhance the danger of reinfection.

The researchers wrote that “viral evolutions might favour reinfections”.

They claimed that recenlty noticed variants “have raised concern on their potential influence in infectivity and immune escape”.

In Brazil, an unnamed 45-year-old nurse got here down with the brand new variant in October – 5 months after she recovered from an older pressure of Covid-19.

Nonetheless, her signs had been worse the second time she caught the virus.

At present, ministers positioned a flight ban on ALL planes coming in from Portugal and all of South America.

The flight ban will come into impact from tomorrow morning, that means anybody can be unable to fly direct from the dozen nations to the UK – however the USA can be spared.

The pressure from Brazil is the third new variant to emerge up to now two months, including to at least one recognized within the UK, and one other in South Africa.

Britain now has three vaccines authorised towards the coronavirus, from drug giants Pfizer, AstraZeneca (Oxford’s) and Moderna.

There are fears the brand new mutations will be capable of dodge the immune system, even after vaccination or earlier an infection.

Professor Sharon Peacock, who’s main analysis into new variants within the UK, stated some mutations are of “adequate” concern to wish in-depth analysis within the laboratory.

And the UK’s Chief Scientific Adviser Sir Patrick Vallance admitted “we don’t know for positive” if the vaccines being rolled out on the NHS will work on the strains from Brazil and South Africa.

He advised ITV’s Peston: “There’s a bit extra of a threat that this would possibly make a change to the best way the immune system acknowledges it however we don’t know.

“These experiments are underway,” Sir Patrick stated.
