South African coronavirus mutation may BEAT current vaccines


Coronavirus vaccines could be ineffective against the highly-infectious South African mutation, a scientist who helped develop the Oxford jab has warned.

Sir John Bell, regius professor of medicine at Oxford, said the African strain is more concerning than the Kent one.

Vaccines are believed to be effective against the highly-infectious UK variant VUI-202012/01 currently causing a massive spike in cases across the country.

But he said the South African variant 501.V2 – detected in two locations in Britain – has ‘really pretty substantial changes in the structure of the protein’ meaning vaccines could be ineffective.

The Covid vaccine protects against the disease by teaching the immune system how to fight off the pathogen.

It creates antibodies – disease-fighting proteins made and stored to fight off invaders in the future by latching onto their spike proteins. 

But if they are unable to recognise proteins because they have mutated, it means the body may struggle to attack a virus the second time and lead to a second infection.

Sir John told Times Radio: ‘The mutations associated with the  South African form are really pretty substantial changes in the structure of the protein.

 ‘My gut feeling is the vaccine will be still effective against the Kent strain

‘I don’t know about the South African strain – there’s a big question mark about that.’ 

Britain first sounded the alarm about the variant VUI-202012/01 in December after an explosion of cases were linked to the strain.

Top virologists in the US since admitted the strain – which was first seen in a patient in September – could have emerged there and went undetected because America’s genomics scheme is ‘sporadic’. 

Australia, Italy, Iceland, Spain and the Netherlands are among the countries who have since reported cases of the UK variant. 

Other Covid strains with near-identical genetic make up have also been reported in South Africa – with strain 501.V2 – and Nigeria – who detected strain P681H. 

South Africa detected 501.V2, which is feared to be more extreme than the UK’s VUI-202012/01. 

Several countries have banned travellers from South Africa to try and contain the spread of the new strain, including the UK, Germany, Saudi Arabia and Turkey. 

But the variant has already been detected in two locations in Britain in contacts of people who had recently visited the African nation. 

On Christmas Eve, another new variant called P681H was detected in Nigeria. 

Scientists say it is different to the other two but they do not currently believe the Nigerian strain is more infectious than previous strains.  

Concerns about vaccine ineffectiveness comes ahead of a major rollout of the Oxford coronavirus vaccine on Monday. 

In the biggest UK mass vaccination drive ever, half a million doses will be made available for vulnerable people this week with ‘tens of millions’ promised by April.

Health Secretary Matt Hancock hailed ‘a historic day and a day of celebration’ over the jab created by Oxford University and at drug giant AstraZeneca.

He said: ‘This is a pivotal moment in our fight against this awful virus and I hope it provides renewed hope to everybody that the end of this pandemic is in sight.’ 

WHERE ARE THE UK’S MASS VACCINATION CENTRES

The UK has approved 40 large-scale vaccination centres. Here is a list of those whose locations have been finalised: 

1. Edinburgh International Conference Centre

2. Newcastle, Centre for Life Science Park

3. Southern Trust – South Lake Leisure Centre, Craigavon

4. Northern Trust – Seven Towers Leisure Centre, Ballymena

5. Western Trust – Foyle Arena, Londonderry

6. Omagh Leisure Complex, Omagh

7. Lakeside Leisure Forum, Enniskillen

8. St Helens, Totally Wicked Stadium

9. Manchester Tennis & Football Centre

10. Derby Arena

11. Birmingham – Millennium Point and Black Country Living Museum, Dudley

12. Leicester Racecourse

13. Stevenage, Robertson House Conference Centre

14. London Nightingale Hospital at the ExCel Centre

15. Epsom Racecourse, Surrey 16. Bristol, Ashton Gate football stadium

17. Exeter, Sandy Park rugby stadium 

Elderly and infirm people in Oxford, London, Brighton, Morecambe in Lancashire and Nuneaton in Warwickshire are due to be first to receive the jab. 

A total of 530,000 doses will be made available at 540 GP vaccination sites and 101 hospitals this week. 

The NHS has ordered 100million doses which it is hoped will free the country from Covid-19. 

An army of current and former NHS staff have applied to give the jabs, with tens of thousands having already completed their training.

The vaccine is the second to be made available after a million Britons received the Pfizer-BioNTech jab. The Oxford vaccine is easier to use, as it does not require storage at extremely low temperatures.

Yesterday Boris Johnson hailed the UK’s vaccine progress. He told the BBC’s Andrew Marr Show: ‘The UK remains the first country to get a stage three approved vaccine into people’s arms. Vaccinating a million people, as we have already, we exceed the whole of the rest of Europe put together.’

A total of 524,439 people already vaccinated are aged 80 and over – around one in five of that age group. 

Supermarket giant Tesco and chemist Boots have offered to help with the rollout of the vaccines. 

Boots is opening three Covid-19 vaccination sites in Halifax, Huddersfield and Gloucester while Tesco will help distribute the Oxford vaccine. 

The Ministry of Defence has deployed 10 military planners to assist the Government’s Vaccine Taskforce, with over 150 personnel working across the UK.

Rollout of the Pfizer/BioNTech jab began almost a month ago. 

But both jabs require second doses which will now take place within 12 weeks rather than 21 days as initially planned to ‘protect the greatest number of people in the shortest time’, health chiefs said.

The Government was yesterday forced to deny claims there was a ‘postcode lottery’ as GPs in some areas have not agreed to deliver the vaccine.
