[국제]”A’universal vaccine’ that catches all COVID-19 mutations is likely to be released within a year.”

[앵커]

The currently developed COVID-19 vaccine appears to be ineffective against some mutant viruses, so the vaccine is being improved again.

It is predicted that a COVID-19’universal vaccine’ that blocks all mutant viruses will be developed within one year without the need to improve the vaccine whenever a new mutant virus appears.

The Pfizer or AstraZeneca vaccine induces the production of antibodies that target the virus’s dendritic protein called Spike.

However, this dendritic protein is well mutated.

This is why the currently developed vaccine is less effective against some mutant viruses.

Vaccine developers are working on improving vaccines to work well with these mutant viruses.

However, if another mutant virus emerges in the meantime, this vaccine cannot be guaranteed.

Because of this, researchers at the UK-based cancer vaccine company Scancell and the University of Nottingham are working on a more fundamental solution.

It is to develop a’universal vaccine’ that blocks all corona 19 viruses, including mutations.

The researchers are working on a vaccine that targets the protein in the core, not the dendritic protein of the virus.

The central part has much less variation than the dendritic protein.

That’s why we can neutralize the virus more reliably.

The researchers found that their experiments in rats had positive results.

In the second half of this year, we plan to conduct tests on the human body.

Of course, this is not an easy task given that there is not yet a general-purpose vaccine that prevents flu mutations.

However, with positive results so far, the researchers say, if well invested, a generic vaccine could be developed within a year.
