Valneva Vaccines Cancelled By UK Just TWO MONTHS Ago Could Be Key To Beating Omicron Strain


Ministers and scientists expressed concern final week that the brand new Botswana Covid variant not solely had the potential to be extra infectious than earlier variants, however that present vaccines is likely to be much less efficient at combating it off.

Final Friday, drug agency Pfizer mentioned it was investigating the mutation – labelled Omicron by the World Health Organisation – to evaluate whether or not an ‘adjustment’ was wanted to its jab.

The American agency mentioned it might develop new doses in six weeks and start delivery in simply over three months.

But consultants informed The Mail on Sunday that there’s one jab able to go that may already be extremely efficient in opposition to this model of the virus: the one developed by French agency Valneva and ordered by the UK Authorities – however then cancelled.

It might have a bonus over present jabs as a result of the best way it’s been made differs.

It incorporates what is called a totally inactivated virus – a complete Covid virus that has been neutralised. 

Although it will possibly’t trigger sickness, the immune system reacts by recognising the menace and creating antibodies and different fighter cells, enabling the physique to battle off the true virus if it turns into contaminated.

Different photographs comparable to Pfizer and AstraZeneca use genetic fragments from one a part of the Covid virus, known as the spike protein – the part that permits it to bind with wholesome cells.

It’s this half that’s vulnerable to mutations: the 32 mutations seen within the Botswana variant are all discovered on the spike protein, which will increase the possibilities that the antibodies developed in response to the above vaccines might not ‘recognise’ it, permitting the virus to slide previous.

For the reason that Valneva jab has extra components of the virus for the immune system to study from, consultants imagine it might be extra ‘variant-proof’ than the others.

Professor Adam Finn, paediatrician and member of the Joint Committee on Vaccination and Immunisation, the Authorities’s advisory group, says there’s a ‘robust theoretical argument’ that the Valneva jab might present safety in opposition to the Botswana variant.

‘That is doubtlessly a extra resilient vaccine,’ he mentioned. 

‘Clearly we’d want to take a look at the way it reacts to this specific variant however I feel there’s a robust argument for doing that proper now.’

Trial outcomes printed final month discovered two doses of Valneva had been 95 per cent efficient at stopping an infection. The trial of 4,000 members additionally reported no instances of extreme sickness.

In December 2020, the UK purchased 100 million doses of Valneva on the recommendation of former vaccine tsar Dame Kate Bingham, who recognized it having a ‘broader immune response’ in opposition to variants. 

Talking in February, she mentioned: ‘That vaccine [Valneva] I think about might get used for pre-winter booster injections that may tackle variants.’

Nonetheless, the UK cancelled its order with Valneva in September, with the Authorities stating the agency had breached the phrases of its provide settlement. Valneva denies this.

Earlier this week, earlier than the invention of the brand new variant, Bingham criticised the cancellation of the contract as ‘inexplicable’. 

Prof Finn, who was chief investigator for the Valneva trials, mentioned the Authorities ought to now rethink Valneva.

‘We have now been very targeted on a number of vaccines on this nation and it’s by no
means a good suggestion to financial institution on one choice. 

‘You want a couple of choice with an unpredictable, harmful variant like this.’

Professor Penny Ward, a pharmaceutical knowledgeable at King’s Faculty London, says if research present vital ‘immune-escape’, then it’s doubtless the UK must run one other booster marketing campaign.

In keeping with Professor Wendy Barclay, a virologist at Imperial Faculty London, it should take a number of months earlier than scientists know the affect of the brand new variant on the vaccines.

She added: ‘We imagine the present vaccines will nonetheless present safety, however it’s potential that for some individuals this safety is likely to be much less.

‘The query is how low will this safety fall to?’
