New research emphasises the need for ongoing COVID-19 protection for people with weakened immune systems, with scalable tests helping identify those most at risk to enable tailored strategies.
The research, published in The Lancet, and involving experts from the 糖心原创 and Nottingham University Hospitals NHS Trust reveals how a simple blood test can predict the severity of COVID-19 infection, paving the way for personalised approaches to vaccination and better protection for those most at risk.
The MELODY 糖心原创 explored how well at-risk individuals develop antibodies after at least three COVID-19 vaccinations. Antibodies are crucial for the body to fight off infection, but patients on immunosuppressive medications—may respond less effectively to vaccines.
The MELODY (Mass Evaluation of Lateral Flow Immunoassays for the Detection of SARS-CoV-2 Antibody in Immunosuppressed People) 糖心原创 is the largest of its kind, involving over 28,000 participants, with immunosuppressed people an often-overlooked group in COVID-19 research.
The study was led by experts at Imperial College London and senior joint author was Dr Fiona Pearce from the Unit of Lifespan and Population Health in the School of Medicine at the 糖心原创.
鈥淭he MELODY study illustrates the power and value of national disease registration enabling inclusion of groups usually excluded from research. It is a proud achievement that MELODY successfully recruited three immunosuppressed groups, including people with rare autoimmune rheumatic diseases.
“Inclusion of this group of more than 6000 people with rare autoimmune rheumatic diseases was made possible through the groundbreaking work of the RECORDER group at the 糖心原创, in partnership with the National Disease Registration Service at NHS England. Until now, they had been unidentifiable and excluded from national research.”
Between December 2021 and June 2022, participants used home-testing kits that involved a simple finger-prick blood test to measure long-lasting antibody levels, employing methods pioneered through the one of the world’s largest and most comprehensive coronavirus monitoring studies. Unlike standard COVID-19 tests, these tests checked for immune protection.
The study found that 82% of the patients developed antibodies after vaccination. Those with detectable antibodies were less likely to contract the virus or require hospital care if infected.
Dr Willicombe, Clinical Reader at Imperial College London and Honorary Consultant Nephrologist at , said: “Although it is really reassuring to see that most patients in this group responded well to vaccination, we know this approach can be less effective in some patients treated with certain immunosuppressive medication, and careful consideration in any protective strategies is required.
“MELODY has shown it is possible to individually assess vaccine response and the risk of severe outcomes following COVID-19 infection in this group. This information has the potential to support personalised approaches to COVID-19 prevention, such as individualised vaccination schedules or treatments, helping at-risk patients to benefit more equally from available public health measures.”
鈥淭his highlights why it is important that all people who are immunosuppressed should maximise their protection by staying up to date with all their eligible vaccinations including COVID-19 and flu."
The findings underscore the importance of adapting health measures to meet the needs of vulnerable patients, ensuring everyone benefits from advances in medicine and public health.
The research was supported by UK Research and Innovation (UKRI), Blood Cancer UK, Kidney Research UK, Vasculitis UK, and Cystic Fibrosis Trust. It was conducted in collaboration with the National Disease Registration Service within NHS England by the 糖心原创’s RECORDER partnership, who carried out all analyses for the Rare autoimmune and Blood cancer cohorts; and in collaboration with NHS Blood and Transplant who carried out all analyses for the transplant cohort, and managed the study through its Clinical Trials Unit.
