The global COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading over the world. However, not much is known about how the adaptive immune response kicks in following the viral challenge. This knowledge is crucial to predicting the efficacy of a vaccine and estimating the chances of reinfection.

Ever since the beginning of the international spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease, researchers have been trying to identify the risk factors that increase the chances of infection. Now, a new study published on the preprint server medRxiv in May 2020 discusses various potential factors and reports the observed associations.

Researchers at the URV have used computer techniques to analyse whether 6,466 drugs authorized by various drug agencies for both human and veterinary use could be used to inhibit the M-pro enzyme. The study demonstrates that a human and a veterinary anti-inflammatory drug - Carprofen and Celecoxib - inhibit a key enzyme in the replication and transcription of the virus responsible for COVID-19. The results of the work have been validated by the initiative COVIDMoonshot.
