Tests for antibodies to spread, more and more

the government should have no Problem with so-called "immunity passes" or "risk-free certificates" as a way of easing the lock, The World Health Organization (WHO) says.

He Said there was "no evidence" that people developed antibodies protected after recovering from The Virus were resistant to a second infection.

a move can, in fact, The Virus transmission increase warned.

people who could be accepted were immune to, the taking of precautionary measures, it Said .

Some governments will have to travel as allows people who have recovered, or to return to work.

- restrictions for the movement to stop the spread of viruses, crippled economies around The World .

More Than 2. 8m cases of The Virus confirmed in The World , and almost 200,000 people died.

What that has to say WHO?

"There is currently no evidence that people who have recovered from Covid-19 and have antibodies shown are protected from a second infection,"

Most of the studies So Far that people who recovered from the infection had antibodies in their Blood , But some of these people had very bodies, small amounts of anti.

This suggests that another part of The Body 's own immune response - T cells eliminate Virus -infected cells, is also "critical" for the recovery.

as of Friday, no study had examined whether The Presence of antibodies transferred against The Virus immunity against subsequent infection by The Virus in people, The Who says.

"At this point in the pandemic, to guarantee there is enough evidence about the effectiveness of the anti-body-mediated immunity, the accuracy of the 'immunity Pass' or 'risk-free" certificate," it Said .

The organization also laboratory tests for the detection of antibodies needs further validation to determine their accuracy and to distinguish necessary between previous infection with the SARS-CoV-2-Virus - Said has caused that pandemic - and the six other known corona viruses in circulation.

passports, too risky - for now

The Who guidelines are based on findings of researchers from all over The World . But it could well change, as we quickly learn more about this Virus .

There is not currently any evidence to suggest that The Virus protects once they time and again. So the idea of an "immunity passport", so that people who test positive for antibodies have less restrictions, would be very risky.

in Many countries are beginning to test samples from their populations for antibodies. In the UK, 25,000 people each month are tested for The Next few years - both for antibodies, and to check whether you are currently infected with The Virus .

This could be more information about whether (and how long) the disease confers immunity for those who have recovered. And that gives us a clearer idea of whether the test individuals, and bestows on them a kind of immunity status could be an option in The Future .

Where are thinking 'immunity passes'?

last week, Chile Said it would have the exhibition "health passports" to the people recovered from the disease.

Once checked, The Presence of antibodies against The Virus immune, you could have Said the labour officials.

In Sweden , has decided to keep large sections of the society open, some scientists believe that people can live in the end with much higher immunity levels in comparison with those under more stringent rules.

Sweden has avoided imposing harsh lockdown measures

told Otherwise wall most of the Swedish Public Health Agency The Bbc that not enough was yet known about immunity.

"We'll know more as more people are tested for antibodies, But also the more time passes, and if there are multiple accounts of re-infection, etc. be reported," He Said .

" In Belgium has one of the highest rates per head of the population, But plans to gradually relax the lockdown restrictions 11. In May , a government adviser told The Bbc he is strongly against the idea of the immunity passes.

"I like the fact that we told people to give passes, a green or a red, depending on the serology status", the virologist Professor Marc Van Ranst, a member of the Belgian government, the risk assessment of the group and of the Scientific Committee on the Coronavirus is hate.

"is That the forgeries will lead people on intentionally infecting themselves with The Virus . This is not just a good idea. It is an extremely bad idea. "

earlier This Week , Professor Mala Maini, University College London reliable antibody detection were urgently needed to determine how long antibodies persist, and whether they confer protection.

"We're still not sure, whether these antibodies have a protective immunity against SARS-CoV-2, But preliminary data suggest that they can be Said to be a reasonable proxy for these - they are so examined, inform, share lockdown, etc," She Said .
