Cancer vaccine could be available by 2030, say scientists behind Covid jab

German couple Professors Ugur Sahin and Ozlem Tureci said they are hesitant to say they can find a cure for cancer, but that they have had "breakthroughs" they will keep working on.

They said the development and success of the Pfizer/BioNTech vaccine against Covid-19 which became widely rolled out in the pandemic "gives back to our cancer work".

The couple - interviewed on BBC's Sunday with Laura Kuenssberg programme - co-founded BioNTech in Mainz, Germany, in 2008, and worked to pioneer cancer immunotherapies tailored to individual patients.

Their use of mRNA technology came into its own in the pandemic, and the couple said that experience has helped to spur on their work.

While conventional vaccines are produced using weakened forms of a virus, mRNAs use only a virus's genetic code.

An mRNA vaccine is injected into the body, where it enters cells and tells them to create antigens which are then recognised by the immune system and prepare it to fight the disease.

Asked when cancer vaccines might be accessed by many patients around the world, Prof Sahin said it could happen "before 2030".

Prof Tureci told Kuenssberg: "What we have developed over decades for cancer vaccine development has been the tailwind for developing the Covid-19 vaccine, and now the Covid-19 vaccine and our experience in developing it gives back to our cancer work.

"We have learned how to better, faster manufacture vaccines. We have learned in a large number of people how the immune system reacts towards mRNA."

She said the developments have also helped regulators learn about mRNA vaccines and how to deal with them.

She added: "This will definitely accelerate also our cancer vaccine."

Taking a positive yet cautious approach, Prof Tureci said: "As scientists we are always hesitant to say we will have a cure for cancer.

"We have a number of breakthroughs and we will continue to work on them."

There is no doubt though that Covid mRNA vaccines have been highly successful and made billions for BioNTech, Pfizer and Moderna.

But a huge legal tussle is under way surrounding the innovation behind mRNA vaccines.

US firm Moderna has started legal action against Pfizer and BioNTech for patent infringement - in essence claiming key elements of their mRNA technology were copied.

Prof Sahin, BioNTech's chief executive officer, says the company will vigorously defend against the allegations.

"Our innovations are original," he said.

"We have spent 20 years of research in developing these type of treatments and of course we will fight for this, for our intellectual property."
