Patterns of utilisation of specialist care after SARS-Cov-2 infection: a retrospective cohort study.

Our findings reflect the burden of post-COVID sequelae, providing some specific insight on their impact on the extra-use of health services according to patients' characteristics and vaccination status. Vaccination is associated with lower cost of care following SARS-CoV-2 infection, highlighting the favourable impact of vaccines on the use of health services even when they do not prevent infection.
