'Promising' coronavirus vaccine found to prevent severe disease in mice
With coronavirus cases around the world now at over 20 million, scientists have been working around the clock to develop a vaccine.
Now, researchers from Washington University School of Medicine have tested an experimental coronavirus vaccine in mice, with promising results.
The tests revealed that the vaccine was able to prevent severe Covid-19 in the mice after just two doses.
The vaccine is made from a mild virus genetically modified to carry a gene from the Covid-19 virus.
Dr Michael Diamond, co-senior author of the study, said: “Unlike many of the other vaccines under development, this vaccine is made from a virus that is capable of spreading in a limited fashion inside the human body, which means it is likely to generate a strong immune response.
“Since the virus is capable of replicating, it can be grown to high levels in the lab, so it’s easy to scale up and should be more cost-effective than some of the other vaccine candidates. So while what we have shown is just the proof of concept, I think it’s very promising.
