Cancer vaccine trials will start in the UK this year after the Government signed a deal with BioNTech, the company that created the mRNA technology behind the Pfizer Covid jab. The so-called cancer vaccines are not preventative but are therapeutic tools designed to fight established disease and advanced tumours. Britain was the first country to give people the BioNTech vaccine, and the company has now invested an undisclosed amount of money to conduct innovative mRNA vaccine research in the UK.
