ABSTRACT:

Background

Individuals may experience persistent symptoms after recovering from coronavirus disease 2019 (COVID-19), a condition referred to as post COVID-19 condition (PCC). Patient-reported outcome measures (PROMs) evaluate a patient's health status and can be used to quantify symptom severity from the patient's perspective. The impact of COVID-19 vaccination and variant of infection on PCC is not well understood. We therefore sought to explore vaccination and variant trends among individuals with PCC and investigate their association with abnormal PROMs.

Methods

Patients seen at Post-COVID-19 Clinics across British Columbia, Canada between March 2020 - Oct 2022 were included in the study. Those who had persistent symptoms, at least one abnormal PROM, and completed a basel
