Two researchers at Karolinska Institutet have been awarded grants from the PolyBio Research Foundation totalling USD 1.85 million dollars (SEK 19 million) for research into long COVID. It is hoped that the studies will provide valuable insights that can promote the development of more efficacious treatments for long COVID, which is still a puzzling condition. Since the outbreak of the pandemic, Marcus Buggert and his group at Karolinska Institutet have studied the COVID-19 virus SARS-CoV-2 in order to identify the underlying causes of long COVID.
