Now, the bad news: Most Americans can’t get vaccinated until next year. In the meantime, new infections, hospitalizations and deaths keep soaring, prompting health officials to urge the public to stay home this Christmas week.
Now travelers risk getting infected with a new variant of coronavirus that may be even more contagious.
What we know about the new variant
A variant of the virus is spreading rapidly in the UK, prompting dozens of new travel bans and raising concerns about what this means for the world.
England’s Chief Medical Officer Chris Whitty warned Saturday that the new variant “can spread more quickly” and was responsible for 60% of new infections in London.
So far, there’s no evidence to suggest the new variant is more lethal, or that current vaccines wouldn’t work against it, Whitty said.
But a virus that spreads more easily could result in more infections, which in turn might lead to more hospitalizations and deaths.
Backward tracing using genetic evidence suggests the new UK variant emerged in September and then circulated at very low levels in the population until mid-November, according to Public Health England.
As of Monday morning, there are no plans to enact a US travel ban against the UK, US Assistant Secretary for Health Adm. Brett Giroir said.
Gounder said a new travel ban might not do much good now. “We have seen this virus circulating within the UK for at least a few months now,” Gounder said.
“Because this virus has been circulating for some period of time in the UK already, the cat’s out of the bag. It has spread elsewhere, including the United States.”
Travel bans can also backfire, Gounder said.
“As we saw when there were efforts to ban travel from China before, people rushed to travel. So the likelihood (is) that that could backfire — that people will actually travel more, all of a sudden, in advance of impending bans.”
How Moderna’s vaccine will be distributed
More than 556,000 people — largely health care workers and nursing home residents — have received their first doses of the Pfizer-BioNTech vaccine.
Now the first public doses of the Moderna vaccine are expected to be given Monday, Operation Warp Speed chief Moncef Slaoui said.
Recipients of the Moderna vaccine should get their second dose 28 days after their first dose.
With the Pfizer-BioNTech vaccine, the two doses should be spaced 21 days apart.
Will the vaccines work against the new variant?
Both the Pfizer/BioNTech vaccine and the Moderna vaccine have shown efficacy rates of around 95% in clinical trials. But many are questioning whether the vaccines would work on new variants of the virus — like one that is spreading in the UK.
“Up to now, I don’t think there has been a single variant that would be resistant to the vaccine,” Slaoui sad. “We can’t exclude it, but it’s not there now.”
He said the novel coronavirus may be prone to variance. But critical aspects of the virus, such as the spike protein involved in a vaccine, are very specific to the novel coronavirus and unlikely to mutate much.
“Because the vaccines are using antibodies against many different parts of the spike protein, the chances that all of them change, I think, are low,” Slaoui said.
Scientists at the Walter Reed Army Institute of Research are examining the variant and expect to know in the next few days if they think vaccines might not work against it.
But most Americans can’t get vaccinated for months.
“So I think what we really need to be doing is focusing on the things we know will prevent spread of this new variant — which is the same thing that works against spread of the coronavirus in general,” Gounder said.
“That is masks, social distancing. If you’re going to be around other people, do it outdoors. And with the holidays coming up, this is really not the time to be traveling.”
Correction: An earlier version of this story and headline incorrectly described Assistant Secretary for Health Admiral Brett Giroir’s comments on vaccine distribution. Health officials are working to have enough doses for 20 million people distributed by the first week of January. He did not promise that 20 million people would be inoculated by that time.
