Scientists involved in potentially game changing research into a COVID-19 vaccine out of the Faculty of Medicine at Macau University
of Science and Technology (MUST) have outlined the key findings of their work, suggesting mass production of the vaccine could be feasible in the near future.

As previously reported by Inside Asian Gaming, the team from MUST, working in collaboration with scientists from mainland China and Hong Kong, found that a vaccine developed using certain residues found in the Spike protein receptor-binding domain (S-RBD) – which is what the virus uses to engage with the cells of the host and cause infection – induced a "potent functional antibody response" in immunized mice, rabbits and monkeys.

These antibodies effectively blocked S-RBD from binding with the host cell receptor as it does in cases of infection, therefore neutralizing the virus during laboratory studies.

The peer-reviewed results from the team's research were published in the leading British science journal Nature last Wednesday 29 July.
