'LITTLE EARLY TO PANIC' — "Any day now." That's when public health officials expect to find the first U.S. case of the Covid-19 Omicron variant. Flights to Europe are still up and running, and Federal Reserve Chairman Jerome Powell signaled today that he's more worried about inflation than an economic slowdown. But what happens when the first case gets here? With the pandemic trajectory riding on whether Omicron turns out to be more transmissible and virulent than Delta, Nightly turned to Akiko Iwasaki, a professor of immunobiology at Yale University to talk through what we know so far about the variant. This conversation has been edited. What worries you about this variant? It's a little early to panic. It does concern me that the Omicron variant has more than 30 mutations in the spike protein, which is the target of vaccines. It is possible to have a virus that is highly transmissible but less virulent. What the virus cares about is the ability to transmit. Whether it leads to a higher disease or not, that's not its concern. Not that it has any brains. But transmissibility also doesn't tell us anything about long Covid consequences, which is huge. Imagine a highly transmissible virus that causes long Covid in 10 percent of the population. That would be terrible. Any data that has been reassuring? There are some reports from the doctors who are taking care of the infected patients saying that it's not causing severe disease yet. That's a little bit reassuring, but the patients are younger. Should people who have gotten the booster shot be worried? In this country, Delta is really the dominant variant. Even with Omicron, you're likely going to be much better off because your level of neutralizing antibodies are so high. The T-cells that are specific to this spike are likely to still detect the antigen from the Omicron variant, which means that they can clear the infected cells and prevent spread throughout the body. What data will you be watching over the next two weeks? Whether it's more transmissible is information that I'm very curious about. Because if it's less transmissible than Delta, then we can really try confining it to where it is currently. The other data that's going to come out fairly quickly is the ability of vaccine-induced antibodies to neutralize the variant. That's an experiment that you can do in the laboratory. I bet that's going to show, probably, significant reduction in neutralization based on what we know already. Should we change our holiday plans? We should have a much better sense of how bad this variant is before the holidays. My plans of visiting Japan are completely off. They have a travel ban now. Never book any tickets that are not refundable. I mean, this is ridiculous, right? It can change every day. Every month since April 2020 our society seems to be ready to declare this thing over. How did we get here? Not being more vigilant about vaccinating the world is really how we get here. There are a lot of issues, not just vaccine unavailability, but also hesitancy around the world. There are countries in which there are plenty of vaccines, but only half the population got vaccinated. We're just not going to be able to control the emergence and the spread of the virus until we get globally vaccinated. Welcome to POLITICO Nightly.
