ColdZyme also blocks omicron variants BA.4 and BA.5
A new study by the Medical University of Innsbruck (MUI) shows that ColdZyme protects airway epithelia from infection with the widespread omicron variants BA.4 and BA.5. This builds upon previous research by the same research group, showing that ColdZyme blocks the original omicron BA.1 variant, which was communicated by Enzymatica in June 2022. The new study is due for publication within the coming months. ColdZyme has now been shown to block 11 respiratory tract viruses and viral sub-variants, including three omicron variants and other coronaviruses. The research group in Innsbruck
