President Donald Trump’s coronavirus vaccine tsar said Monday he expected Pfizer and Moderna’s Covid-19 shots to be effective against a new mutation of the virus found in the UK

The comment came after the UK identified a new mutation of the virus on Saturday that can spread faster than previous variants. Countries like Italy, Germany, Canada and Israel have suspended flights from the UK after reports of the new strain.

The mutations involve changes in the spike protein that the virus uses to infect human cells. The vaccines induce an immune response against multiple structures around the spike protein, a multifunctional mechanism that allows the virus to invade the host, said Dr. Moncef Slaoui, scientific advisor to Trump’s Operation Warp Speed ​​vaccination program, told reporters during a press conference. The likelihood that a set of mutations will completely change these structures “is extremely small,” he added.

Both Pfizer and Moderna’s vaccine use messenger RNA or mRNA technology. It’s a new approach to vaccines that uses genetic material – in this case a harmless piece of spike protein – to trigger an immune response against the virus.

Slaoui said he spoke to UK health officials about the new strain on Monday. To date, he said there is no “hard evidence” that the virus is more easily transmitted than the original strain of the disease.

“There is strong evidence that there is more of this in the population,” he said, adding that the emergence of the new strain is also due to the fact that scientists are now able to track variants of the virus more quickly. Before British scientists may not have looked for this variant and infections appeared in the “shadows”, he said.

A safe and effective vaccine is viewed by investors and policymakers as a solution to getting the global economy back on track after the pandemic wreaked havoc in almost every country in the world and in emerging businesses.

Americans are expected to receive some of the first shots of Moderna’s vaccine on Monday after the Food and Drug Administration approved the vaccine for emergency use on Friday. The US will distribute 5.9 million doses of the vaccine across the country this week, as well as 2 million doses of the Pfizer vaccine, which was approved for emergency use on Dec. 11, health officials said Monday.
