Covid vaccine to be tested in people with weak immunity


Patients with certain immunosuppressed conditions, such as cancer, inflammatory arthritis, diseases of the kidney or liver, or who are having a stem cell transplant, may be at increased risk of the more severe complications of Covid-19 infection.

These underlying medical conditions and the treatment the patients receive, may weaken the immune system which could make vaccines particularly essential for such patients.

But researchers have warned that current evidence suggests that people with these medical conditions may not obtain optimal protection from established vaccines.

The new Octave trial will seek to better determine the effectiveness of Covid-19 vaccines in these clinically at-risk patient groups.

The trial, funded by the Medical Research Council (MRC), is a collaborative research project involving groups in the Universities of Glasgow, Birmingham, Oxford, Liverpool, Imperial College London and Leeds Teaching Hospitals NHS Trust.

Professor Iain McInnes, Head of the College of Medical, Veterinary and Life Sciences at the University of Glasgow, who leads the Octave study, said: “We urgently need to understand if patient populations with chronic conditions such as cancer, inflammatory arthritis and kidney and liver disease are likely to be well-protected by current Covid-19 vaccines.

“The Octave study will give us invaluable new data to help us answer questions of this kind from our patients and their families.”

The Octave study will investigate the effectiveness of Covid-19 vaccines being used in the UK in 2021, in up to 5,000 people within these patient populations.

Using a variety of state-of-the-art immune tests performed on blood samples taken before and/or after Covid-19 vaccination, researchers will determine patients’ Covid-19 immune response and therefore the likelihood that vaccines will fully protect these groups from infection.

Researchers have begun recruiting patients at sites across the UK and will compare results from the study group against control groups of healthy people, without these underlying diseases, who also received Covid-19 vaccines.

Scientists do not yet know how long Covid-19 vaccines provide immunity for, and there may be an ongoing need for vaccination against the disease for years to come.

Coronavirus vaccine in numbers: More than 21 million vaccinations administered

Professor Fiona Watt, executive chair of the Medical Research Council, which funded the study, added: “This study is investigating the response to the new Covid-19 vaccines in people whose immune systems make them more vulnerable to Covid-19 and other infections.

“This will help ensure that those more at risk from infection receive the best protection possible.”

The Octave study is sponsored by the University of Birmingham and is being run by the University’s Cancer Research UK Clinical Trials Unit (CRCTU).

University of Birmingham Professor Pam Kearns, Director of the CRCTU, said: “We are pleased to be supporting this important nationally collaborative study that will inform the best use of the Covid-19 vaccines to protect these vulnerable patients.”
