Circular RNA vaccine shows neutralizing activity against B.1.351 variant

New preclinical research led by Wensheng Wei from Peking University in China has proposed the development of a circular RNA vaccine. Their findings showed the circular RNA vaccine creates neutralizing antibodies and strong T-cell responses against the receptor-binding domain of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein.
