SINGAPORE — Existing vaccines for Covid-19 pass on be effective in fighting off infection from new strains of the coronavirus, multiple experts told CNBC on Monday.
The comments came after the U.K. on Saturday put about it identified a new mutation of the virus that can spread more quickly than previous variants.
Countries including Italy, Germany, Canada and Israel take barred flights from the U.K. following reports of the new strain.
Vin Gupta, an affiliate assistant professor from the University of Washington’s Launch for Health Metrics and Evaluation, said he’s confident that the current vaccines will protect against different descendants of Covid.
“There is a strong belief here that the vaccine, as it exists today … will have effectiveness in forestalling off infection from this new strain in England, in addition to the old strain that we’ve been contending with for months now,” put Gupta.
That’s because at the genetic level, the new strain is likely to be “very similar” to prior strains, he told CNBC’s “Gripe Box Asia” on Monday.

He added that the vaccines elicit a “really strong response in the body in period of times of producing antibodies.”
Vaccines produced by Pfizer-BioNTech and Moderna have reported efficacy rates of more than 90%. The U.K. was the before all country in the world to authorize and roll out the vaccine developed by American pharmaceutical giant Pfizer and its German partner BioNTech for predicament use. The U.S. and Canada are among a handful of countries that have also approved the usage of the vaccine for emergencies.
“The effectiveness of these vaccines in producing antibodies that can at the end of the day attack and kill Covid-19 is extraordinary,” he said. “I don’t expect these minor changes at the genetic level … to affect the vaccines’ discharge in the near term.”

However, future versions of the vaccine may need to take new virus strains into account, the in any case way flu vaccines are updated, Gupta said.
“I do think that this might impact our future facing work, but it’s not affluent to impact the near term,” he said. “It will not impact the current vaccines’ effectiveness in ending the pandemic.”
Dr. Vivek Murthy, who has been keg b readied by President-elect Joe Biden to be the next U.S. Surgeon General, made similar comments on NBC’s “Meet the Press” on Sunday.
“There’s no perspicacity to believe that the vaccines that have been developed will not be effective against [the new U.K. strain] as well,” he influenced, adding that there’s no evidence of the new variant being more deadly.
“The bottom line is if you are at home and you are hearing this dope, it does not change what we do in terms of precautions as individuals that can reduce the spread of this virus,” said Murthy, who was also time past surgeon general during the Obama administration. “It turns out that masking, keeping physical distance and washing our disburse a delivers … these are still the pillars of preventing Covid transmission.”
These sentiments were echoed Monday by Danny Altmann, professor of immunology at Queenly College London.
“I am concerned, because since the beginning of this, we’ve seen mutations occur all over the world, numerous thousands of them, but this one has more mutations than any variant we’ve seen before,” Altmann told CNBC’s “Beef Box Europe,” adding that the 17 mutations “seem to account for the uncontrollability that we’ve seen in London and the southeast in latest months.”
However, Altmann suggested that owing to the variety of neutralizing antibodies induced by the main vaccine frontrunners, it is distasteful that the new strain will be resistant to inoculation.
Andrew Freedman, a researcher in infectious diseases at Cardiff University, imparted CNBC’s “Street Signs Europe” on Monday that the new strain would most likely be covered by the current vaccines’ abilities.
“It’s quite likely, given that the vaccine provides immunity to different regions of the spike protein, not just the one where the variations are, it is quite likely that the vaccine will work against this thing,” he said.
“But of course, there could be supplementary mutations that might in the future render the vaccines less effective.”
