The Omicron Covid variant has a ‘significant’ ability to evade immunity from a previous infection, the first real-world study of the new variant has suggested.

New research claims it can spark a new wave of infections – even in populations with high levels of antibodies.

It remains to be seen how well existing vaccines provide protection against Omicron, the scientists said in the paper, has yet to be reviewed.

They warn: ‘Urgent questions remain regarding whether Omicron can avoid vaccine-induced immunity and the potential effects of reduced immunity to infection. in protecting against serious illness and death.’

It comes after nearly 2.8 million confirmed cases across South Africa were reviewed, starting in March 2020.

The findings suggest that the risk of reinfection is lower in the Beta and Delta waves than in the first strain of the virus, which is believed to have originated in Wuhan, China.

But the risk of reinfection with Omicron is 2.4 times higher than in the first wave, researchers at South Africa’s National Institute of Infectious Diseases (NICD) wrote.

They said: ‘We find evidence of a significant and ongoing increase in the risk of reinfection, which is consistent in time with the emergence of the Omicron variant in South Africa, suggesting Its selective advantage is at least partly driven by its increased ability to infect people who have been previously infected. ‘

However, the new study comes after the South African doctor who discovered Omicron revealed that the patient had experiencing ‘extremely mild’ symptoms in her country.

Dr Angelique Coetzee has suggested that countries may be needlessly panicking about the new strain of Covid.

Barry Schoub, chairman of the South African government’s committee on a coronavirus vaccine, also said early signs were ‘good news’.

He said: ‘Our hospital surveillance is getting a little up, but certainly not as dramatic as we’ve seen in previous waves.’

Meanwhile, the boss behind the Pfizer vaccine insists the people who threw stones at his product were likely to remain protected from serious illness.

Immunologist Dr. Ugur Sahin told The Wall Street Journal: ‘Don’t worry, the plan remains the same: Speed ​​up the execution of the third booster shot.’
