The effectiveness of Covid-19 vaccines to prevent Long Covid symptoms: staggered cohort study of data from the UK, Spain, and Estonia (18 January 2024)

Summary

This cohort study in the Lancet aimed to evaluate the overall effect of vaccination to prevent Long Covid symptoms and assess comparative effectiveness of the most used vaccines (ChAdOx1 and BNT162b2). The results showed that vaccination against Covid-19 consistently reduced the risk of Long Covid symptoms, which highlights the importance of vaccination to prevent persistent Covid-19 symptoms, particularly in adults.
