The US drugs giant has revealed plans to use gene-based technology, harnessed by BioNTech, to tackle other viruses and illnesses beyond Covid.
Pfizer’s boss claimed the firm had learned enough about mRNA vaccines to go solo, adding that it no longer ‘needs to work with BioNTech’ beyond the end of the companies’ flu jab agreement in July.
Albert Bourla, the firm’s chief executive, revealed the company had recruited at least 50 more scientists to work out of its new mRNA-focused lab in New York.
It has also secured specialised raw materials and designed clinical trials so that it can manufacture and study vaccines without splitting profits.
Mr Bourla told the Wall Street Journal: ‘We like working with BioNTech, but we don’t need to work with BioNTech. We have our own expertise developed.’
The German company was the brains behind the Covid jab, which was proven to be 95 per cent effective at blocking Covid symptoms and became the first in the world to get approval in December when Britain gave it the green light.
Pfizer, most famous for inventing Viagra, came on board to manufacture, distribute and commercialise the vaccine.
The two companies are currently splitting profits on the Covid jab evenly, with sales expected to return roughly £13billion this year.
BioNTech seemed unaffected by the news in a statement and said it welcomed the ‘acknowledgement’ of the technology it had developed.

Analysts at JP Morgan forecast more than £8.5bn in sales for the jab next year, which will increase if annual booster shots are needed.
BioNTech is expected to supply one billion doses of the jab this year, a target that increased by a quarter when it got approval for its factory in Marburg, Germany.
And Pfizer is matching this with another billion, bringing the pair’s total to two billion.
A BioNTech spokeswoman told the WSJ: ‘We consider it a great acknowledgment for mRNA technologies that companies such as our partner Pfizer are getting involved into building their own mRNA vaccine strategy.’
The two firms first began to collaborate in 2018 with the aim of making a flu vaccine.
But that original deal expires this July, at which point Pfizer will continue to research, manufacture and sell any jab proven to work.
How do mRNA vaccines work?
MRNA is a next generation technology, or platform, to use vaccine terminology.
Traditional vaccines use one harmless, typically inactivated virus – such as the types that cause common colds – to deliver a tiny, harmless piece of the virus that the shot will provide protection against to the human body.
The piece is enough to ‘teach’ the immune system how to recognize and fend off the invader.
MRNA is easier and faster to make, and much more easily modified than older types of vaccines, and even has the potential to provide protection against multiple viruses in one vaccine.
The coronavirus vaccine is made from volatile genetic material known as mRNA, or messenger RNA, tiny pieces of genetic material that mimic the coronavirus so the immune system can learn to spot and destroy it.
Scientists say mRNA vaccines are cheaper to make and easier to modify in the face of new variants or viruses.
The process of developing mRNA vaccines is also purely synthetic, meaning experts don’t have to rely on living cells from plants or animals.
Making mRNA vaccines requires special equipment and raw materials that weren’t commonly available before Covid hit.
Pfizer/BioNTech’s Covid jab was the first ever mRNA vaccine to get approval for fighting any disease. Rival American firm Moderna has also created an mRNA jab proven to thwart coronavirus.
Pfizer’s boss said it has become self-sufficient after learning how to produce mRNA vaccines itself, without relying on suppliers.
The New York-based firm, which is one of the world’s biggest pharmaceuticals, has declined to say which viruses it will target next with the mRNA technology.
But it’s likely booster coronavirus shots will be needed in the future as new variants emerge. The global flu vaccination market is also valued at about £3bn.
Pfizer’s vaccine portfolio already includes one of the most profitable jabs on the market — the pneumonia vaccine Prevnar 13. It made Pfizer nearly £4.3bn in sales last year.
Single dose of Pfizer/BioNTech jab provokes ‘robust’ immune response in 9/10 people
A study has found a single dose of Pfizer’s jab produces a ‘robust’ immune response in 99 per cent of people.
Experts said levels of protection are even stronger after the top-up jab, underlining the importance of people coming forward for their second shot.
Data showed the jabs offered a ‘breadth’ of immune response, leaving experts confident that the current crop of vaccines should be effective against the South African variant and other mutant strains.
The findings support the UK policy of rapid roll-out of one dose of vaccine to provide cover as quickly as possible for millions of Britons in higher-risk groups, researchers say.
The study was done on 237 health workers in Sheffield, Oxford, Liverpool, Newcastle and Birmingham. Most volunteers were female.
It measured levels of both antibodies and T-cells, which are substances used by the immune system to destroy the coronavirus. Higher levels generally mean stronger immunity.
Scientists found that, after one dose of the vaccine, people who had been infected with Covid in the past had 6.8 times as many antibodies in their blood as those who had not.
They had 2.9 times as many antibodies after one dose as people who had not been infected but who had been given two jabs, the total vaccine course.
But the experts said second doses are still needed for everyone because the booster is thought to make immunity last for longer.
It is also using traditional vaccine technology to develop shots for Lyme disease and colon infections.

The scientist behind Pfizer’s vaccine says the technology could soon be used to fight cancer.
Ozlem Tureci, who co-founded BioNTech with her husband, was working on a way to harness the body’s immune system to tackle tumours when they learned last year of an unknown virus infecting people in China.
And within 11 months, Britain had authorised the use of the mRNA Covid-19 vaccine they developed with US pharmaceutical giant Pfizer, with approval from the US following a week later.
Tens of millions of people worldwide have received the shot since December.
‘It pays off to make bold decisions and to trust that if you have an extraordinary team, you will be able to solve any problem and obstacle which comes your way in real time,’ Tureci said.
Among the biggest challenges for the small, Mainz-based company that had never brought a product to market before was how to conduct large-scale clinical trials across different regions and how to scale up the manufacturing process to meet global demand.
Along with Pfizer, the company enlisted the help of Fosun Pharma in China ‘to get assets, capabilities and geographical footprint on board, which we did not have,’ Tureci said.
Among the lessons she and her husband, BioNTech chief executive Ugur Sahin, learned along with their colleagues was ‘how important cooperation and collaboration is internationally.’
Tureci, who was born in Germany to Turkish immigrants, said the company, which has staff members from 60 countries, reached out to medical oversight bodies from the start, to ensure that the new type of vaccine would pass the rigorous scrutiny of regulators.
‘The process of getting a medicine or a vaccine approved is one where many questions are asked, many experts are involved and there is external peer review of all the data and scientific discourse,’ she said.
Moderna jabs will be rolled-out in 3 weeks to the under-50s as Britain’s vaccine drive shifts up a gear
Britain’s world-beating vaccine rollout will move up another gear in mid-April when the Moderna jab is deployed for the first time, The Mail on Sunday understands.
The imminent arrival of more than 500,000 doses of the new US vaccine – to add to millions of Pfizer and Oxford-AstraZeneca shots – will herald the expansion of the programme to the under-50s.
Doctors are expected to administer the first Moderna jabs within three weeks.
Moderna, which was codenamed ‘Renown’ by the Government during the American company’s development process, is being manufactured by the Swiss-based Lonza biotech company.
Trials found that it was 94.1 per cent effective at preventing symptomatic infection after the second dose.
More than 30 million vaccine first doses have now been administered in the UK.
