Vaccine effective against all variants of SARS-CoV-2 has been developed in Vienna

Preclinical data on the SARS-CoV-2 vaccine developed at MedUni Vienna show that it is effective against all known variants of SARS-CoV-2, including Omicron - even in individuals who have not yet developed immunity to SARS-CoV-2 as result of vaccination (unresponsive cases). The survey data was recently published in the leading journal Allergy.
