Scientists had expected that the vaccines authorized now or in development wouldn't be taken down by single mutations.
Pledging that more brands will be given greenlight "in the coming weeks and months", Von der Leyen said the European Union has so far secured up to 2.3 billion doses from the most promising vaccine candidates for the European Union and its neighborhood.
Dormitzer said it was encouraging that the vaccine appears effective against the mutation, as well as 15 other mutations the company has previously tested against.
He said, as cited in the Mirror Online report: "So we've now tested 16 different mutations, and none of them have really had any significant impact". They have said they expect them to be effective, but the timing of those studies are not known.
A In line with worldwide standards, only Covid-19 vaccines that are at least 50 per cent effective at preventing the disease will be approved. The second dose of Moderna's vaccine is administered 28 days apart from the first, and the Pfizer-BioNTech vaccine's second dose is provided 21 days from the first dose.
The agency also said it also does not recommend Covid-19 vaccination of travelers unless they face high risks or qualify as priority cases.
The Ontario government has said it expects to receive approximately 80,000 doses of the Pfizer vaccine the week of January 11, and another 80,000 doses the week of January 18.
Vaccine manufacturers Pfizer-BioNTech and Moderna have publicly stated that their vaccines are likely to protect against the new strain, and are undertaking studies to formally confirm this.
Quebec has administered almost 40,000 doses of the vaccines.
A mutation found in fast-spreading coronavirus variants does not negate the Covid-19 vaccine from Pfizer and BioNTech, researchers reported late Thursday. UK Prime MinisterBoris Johnson said it will be these vaccines that provide the "means of escape" from lockdown and has pledged daily vaccination updates starting next Monday. "However, it is important to get a more definitive answer with the complete variant containing all 8 mutations".
"We are encouraged" by the early findings, Pfizer Chief Executive Officer Albert Bourla said in a tweet.
Viruses constantly undergo minor changes as they spread from person to person.
