‘We Cannot Continue With Christmas’: U.K. Tightens Rules As Virus Variant Spreads

It will take about two weeks to get the data about whether the vaccine is effective against the variant, which he said would be published.

Sahin was pressed on how quickly the company could ramp up production of a new vaccine, should a significant mutation of the coronavirus emerge.

«We can directly start to engineer a vaccine which completely mimics this new mutation and we could be able to provide a new vaccine, technically within six weeks, Sahin added.

But he added that an important factor to consider is how quickly various regulators, like the U.S. Food and Drug Administration and European Medicines Agency, would authorize the use of a hypothetical new vaccine.

It is important to note, as NPR’s global health correspondent Michaeleen Doucleff reported on Tuesday, that the coronavirus that causes COVID-19 «has been mutating the whole time during the pandemic, averaging one to two mutations a month.

What makes the U.K. variant so noteworthy is that it has 17 mutations, she reported.

«And many of those mutations are in what’s called the spike protein. This is part of the virus that reaches out and binds to human cells, which then leads to infection, Doucleff said.

Scientists discovered one of the mutations in the U.K. variant enables the virus to bind more tightly to human cells, Doucleff added. Overall, she said scientists think these changes are «helping it to adapt to humans and possibly spread more easily.

In response to the variant, nations in Europe and across the globe have barred travelers from the U.K.

More than 40 countries have imposed travel restrictions, the BBC reported, causing delays at ports and long lines at tunnels leading out of the U.K.
