Computer simulated model of COVID-19 spike protein binding to the human ACE2 receptor through which it gains entry into cells lining the human lung. Vaxine’s COVID-19 vaccine is designed to mimic the portion of the spike protein attaching to ACE2, with the aim of inducing human antibodies that will bind to the COVID-19 spike protein thereby blocking it from binding to ACE2 and getting inside human cells thereby preventing infection.
