In a recent study published on the medRxiv* preprint server, researchers in Switzerland investigated the association between post-coronavirus disease 2019 (COVID-19) condition (PCC) six months after infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta or Omicron variant of concern (VOC) and prior COVID-19 vaccination as compared to infection with the SARS-CoV-2 wildtype (WT) strain in non-vaccinated individuals.

PCC, often referred to as ‘long COVID,’ is a critical COVID-19 complication that has significantly impacted human lives globally.
