Vaccinated individuals infected with Omicron less likely to experience long COVID symptoms Coronavirus Disease COVID Omicron Vaccine LongCOVID UZH_en USI_university medrxivpreprint
By Pooja Toshniwal PahariaOct 2 2022Reviewed by Benedette Cuffari, M.Sc. In a recent study published on the medRxiv* preprint server, researchers in Switzerland investigated the association between post-coronavirus disease 2019 condition six months after infection with the severe acute respiratory syndrome coronavirus 2 Delta or Omicron variant of concern and prior COVID-19 vaccination as compared to infection with the SARS-CoV-2 wildtype strain in non-vaccinated individuals.
Data were obtained prospectively through online questionnaires from two cohorts diagnosed with COVID-19 between August 5, 2020, and February 25, 2022. In addition, the Zurich SARS-CoV-2 and Corona Immunitas seroprevalence study cohorts were included. In the sensitivity analyses, patients were categorized with mild, moderate, or severe COVID-19 based on the EuroQoL visual analog scale . All Zurich SARS-CoV-2 cohort participants were categorized as WT-infected.
Multivariable and multinomial logistic regression models were used for estimating PCC risk reductions and severity, respectively, and the odds ratios were calculated. In addition, exploratory hierarchical cluster analyses were performed to identify clusters of individuals with similar symptoms and evaluating differences in PCC presentation across VOCs.
Omicron-infected and vaccinated individuals had lower PCC risks than WT-infected and unvaccinated individuals, with an OR 0.4, irrespective of COVID-19 severity. No significant differences were observed in the prevalence of PCC concerning vaccination doses received or the timing of the most recent vaccination, with sensitivity analyses showing similar results.
