While vaccines have proved effective to prevent severe COVID-19, their impact to prevent long-term symptoms have not yet been fully understood. But a research team at the University of Oxford's Nuffield Department of Orthopaedics, Rheumatology, and Musculoskeletal Sciences (NDORMS) has found that vaccination against COVID-19 consistently reduced the risk of long COVID symptoms. These vaccines proved to be highly effective in preventing severe COVID-19 but it’s known that around 1 in 10 people suffer from persistent symptoms, what we call long COVID. Dr Annika Jodicke, Senior Pharmacoepidemiologist and study co-lead, said: ‘We were able to demonstrate how both vaccines prevented the development of persistent COVID symptoms. The study, 'The effectiveness of COVID-19 vaccines to prevent long COVID symptoms: staggered cohort study of data from the UK, Spain, and Estonia', is published in The Lancet Respiratory Medicine.
