Oxford: No evidence that current vaccines have failed against Omicron

Oxford University has claimed there are none prove that current vaccines do not provide some protection against the omicron variant, as scientists rush to evaluate the new Covid-19 mutation.

The university pointed out on Tuesday that despite the emergence of new variants over the past year, the vaccines have continued to provide very high levels of protection against serious diseases, and there are not yet. prove that Omicron is completely different.

Drug manufacturers are rushing to test their vaccines and treatments against the Micron, amid indications that it can spread faster and avoid vaccine protection due to the large number of spiny proteins that appear on it. .

Companies and scientists have said it will take a few weeks for the true impact to be known, with little data yet.

In turn, AstraZeneca, which developed a Covid-19 vaccine with the University of Oxford, is testing its vaccine and is already conducting research. in countries like Botswana.

He added that Oxford had “the tools and processes in act “to quickly modify the vaccine to target omicron if necessary.

For its part, Pfizer said it will know within the next two to three weeks how successful its vaccine will be in resisting the Micron, while executives senior di Moderna confirmed that numerous mutations in the alternative indicate that new vaccines are needed.

The head of the European Medicines Regulatory Authority asked the European Parliament on Tuesday that it was not known whether the amendments would be necessary, but that it would take three to four months to ratify a new version of a developed vaccine.

The omicron variant has alarmed scientists due to the large number of mutations it contains, far more than the highly transmissible delta variant. Most of the changes are due to the virus’s skeletal protein, which it uses to enter cells and which has been the target of current licensed vaccines.
