Thousands of NHS cancer patients in England are set to gain access to trials of a groundbreaking new treatment using vaccines to combat their disease.
So far, thirty hospitals have joined the Cancer Vaccine Launch Pad, an initiative designed to connect patients with upcoming trials utilizing mRNA technology, similar to that found in current Covid vaccines.
These vaccines are tailored to prime the immune system to recognize and eliminate any remaining cancer cells, aiming to reduce the risk of cancer recurrence.

Elliot Pfebve, 55, is the first patient in England to receive a personalized vaccine against bowel cancer. Having already undergone surgery and chemotherapy, Elliot received his vaccine at Birmingham’s Queen Elizabeth Hospital.
He expressed his excitement about the trial, noting the potential for a significant medical breakthrough. “If successful, it may help thousands, if not millions of people, giving them hope and possibly preventing them from experiencing what I have gone through,” he said.
Following his initial treatments, tests revealed that Elliot still had fragments of cancerous DNA in his bloodstream, which increases the risk of cancer returning. Consequently, he joined a trial for an experimental vaccine made by German pharmaceutical company BioNTech, employing the same mRNA technology as the Pfizer-BioNTech Covid vaccine.
Cancer vaccines differ from traditional vaccines, which are generally designed to prevent diseases. Instead, cancer vaccines are used as a treatment for patients already diagnosed with cancer. These vaccines prime the immune system to target the specific cancer cells.
In Elliot’s case, a sample of his tumor was sent to BioNTech’s labs in Germany, where up to 20 mutations specific to his cancer were identified. Using this data, a vaccine was created with mRNA that instructs Elliot’s cells to produce mutated proteins unique to his cancer cells.
This vaccine acts like a ‘wanted poster,’ helping the immune system recognize and destroy the cancer cells that might otherwise hide in the body and resurface later.
Dr. Victoria Kunene, the trial’s principal investigator from Queen Elizabeth Hospital Birmingham, expressed optimism about the new treatment.
“I think this is a new era. The science behind this makes sense. My hope is this will become the standard of care, helping patients reduce their risk of cancer recurrence,”
While the potential for mRNA cancer treatment vaccines is promising, they remain experimental and are currently available only through clinical trials. Over 200 patients from the UK, Germany, Belgium, Spain, and Sweden will participate in the trial, receiving up to 15 doses of the personalized vaccine. The study is not expected to be completed until 2027.
One anticipated benefit of these vaccines is fewer side effects compared to conventional chemotherapy. Elliot reported only a mild fever following the injection with no other significant issues.
Amanda Pritchard, NHS England chief executive, described Elliot’s treatment as a landmark moment in the development of more effective cancer treatments. Prof. Peter Johnson, NHS national clinical director for cancer, added that while cancer can sometimes return post-surgery due to residual cells, using a vaccine to target these cells might prevent recurrence.
Last month, a patient in London received a personalized mRNA vaccine against melanoma, the most dangerous form of skin cancer, created by Moderna. Both Moderna and BioNTech are planning or conducting trials for mRNA vaccines targeting various types of tumors, including lung, breast, and bladder cancers.
Bowel cancer symptoms to watch for include changes in bowel habits, such as softer stools, diarrhea, constipation, blood in the stool, bleeding from the rectum, persistent need to defecate, abdominal pain, lumps, bloating, unexplained weight loss, and fatigue. While these symptoms are common and often linked to other conditions, it is crucial to consult a GP for proper diagnosis and treatment.
