COVID-19
Drug repurposing for the battle against COVID-19 The race has been on since the start of the pandemic to develop vaccines and drugs to fight against the SARS-CoV-2 virus. Vaccine development has proven successful, with vaccine roll-out underway in many countries, but the need remains to identify drugs that can treat the disease for those who have not been vaccinated, or for those where the vaccine is not effective enough to prevent disease. Researchers at the Fraunhofer Institute for Translational Medicine and Pharmacology (ITMP) in Hamburg, Germany, have been using high throughput drug approaches to screen compound libraries for candidate antiviral drugs. The SARS-CoV-2 virus was identified,
