Coronavirus vaccine: Scientists say it will be effective against all its mutations


Experts from CSIRO confirmed their hypothesis by experimenting on ferrets infected with two different coronavirus mutations, originally the dominant form D and now the predominant G variant. At the disposal of one of the potential vaccines, they have been shown to be equally effective against both the D mutation and the G mutation.

This fact also means that an effective vaccine will not have to be changed and adapted as often, perhaps even at all, as it does with influenza vaccination. The coronavirus has been mutated since it first appeared in Wuhan, China, at the end of the year, and experts feared that vaccines being developed based on information about the original version of the virus would not be effective.

The vaccine will not need to be treated like the flu

At the beginning of the pandemic, a version of covid-19, now known as the D mutation, dominated. This time in one specific location marked with the number 614 mutated to variant G, the amino acid aspartic acid was changed to glycine, hence the designation G. Virus mutations are very common and usually complicate work on the vaccine, as is evident for flu vaccinations, which need to be constantly updated.

Experts therefore feared that the same would be true for coronavirus, that it would prepare a new vaccine for each version of the virus. CSIRO research has reached groundbreaking conclusions and allayed all fears, Form D and G respond equally to treatment, so one vaccine is enough. Option G now accounts for 85 percent of all active cases. At the beginning of a pandemic, it was rare, for example, one US hospital had 99 percent of the D mutation in the spring and only one percent of Form G.

In Indonesia, a coronavirus mutation struck.  It's ten times more contagious, but not so deadly

“This is great news for the hundreds of vaccines that are under development around the world. Our research has shown that vaccines will also be effective on mutations. “ commented research leader Seshadri Vasan. “We also found that there would be no need to adjust the vaccine every year, as is the case with influenza,” he boasted.

SCIRO: We’re one step closer to success again

“A study presented by our specialists has taken the world one step closer to discovering an effective vaccine that will protect people and save countless lives.” SCIRO head Larry Marshall evaluated the work of experts. “The research was possible so quickly only with the collaboration of scientists not only from Australia but from all over the world.” assessed Marshall.

THE mutaci G is said to be although more contagious than version D, but not so deadly however, according to some experts, this is a hypothesis controversial.
