But questions remain about how protected the public will be in coming months, as cases of new variants inch upward. One in particular, BA.2.86, is raising alarms since the U.S. Centers for Disease Control and Prevention (CDC)[ ](https://www.cdc.gov/respiratory-viruses/whats-new/covid-19-variant.html)[warned](https://www.cdc.gov/respiratory-viruses/whats-new/covid-19-variant.html) that it “may be more capable of causing infection in people who have previously had COVID-19 or who have received COVID-19 vaccines.” The growing number of BA.2.86 cases not just in the U.S. but around the world prompted the World Health Organization to [classify](https://www.who.int/activities/tracking-SARS-CoV-2-variants) it as a “variant under monitoring” as scientists continue to study how well the virus can spread and whether it can cause more serious disease than previous variants. The biggest question is [how well new vaccines](https://time.com/6308418/ba-2-86-covid-19-variant-vaccine/) that U.S. health officials recommended earlier this summer will protect against BA.2.86\. That recommendation came well before BA.2.86 appeared, and vaccine makers have already been producing those versions of the shot in preparation for the fall and winter. In a press release issued on Sept. 6, one of those manufacturers, Moderna, reported that its latest vaccine generates a strong immune response against BA.2.86, helping the immune system to produce 8.7- to 11-fold more antibodies capable of neutralizing the variant compared to before vaccination. The updated vaccine also generated neutralizing antibodies[ ](https://time.com/6308418/ba-2-86-covid-19-variant-vaccine/)[against other new variants EG.5 and FL.1.5.1](https://time.com/6308418/ba-2-86-covid-19-variant-vaccine/). The data came from studies involving immune cells from a group of 50 people who had been up to date with their vaccines, with a most recent booster shot targeting BA.4/5. ### More From TIME The results are encouraging, since this updated vaccine was not developed specifically to target BA.2.86, but XBB.1.5, the variant that was causing most infections earlier in the summer when the Food and Drug Administration’s (FDA) vaccine committee met. The FDA’s panel of independent vaccine experts[ ](https://time.com/6287732/new-covid-19-vaccine-strains/)[suggested](https://time.com/6287732/new-covid-19-vaccine-strains/) targeting a member of the XBB variant family, and[ ](https://www.fda.gov/vaccines-blood-biologics/updated-covid-19-vaccines-use-united-states-beginning-fall-2023)expressed a [preference](https://www.fda.gov/vaccines-blood-biologics/updated-covid-19-vaccines-use-united-states-beginning-fall-2023) for targeting XBB.1.5, which Moderna and other manufacturers did. The results are reassuring, says Jackie Miller, senior vice president of infectious disease at Moderna, because “there was certainly a question about whether there would be cross-neutralizing protection observed or not because of the differences between the lineages \[of XBB and BA.2.86\].” She says that BA.2.86 binds to human cells in a different way than previous variants have, which raised concerns that it could cause more severe disease. But that difference in how it infects cells is counterbalanced by the fact that the attachment is less efficient, so “what emerging data are showing is that this binding does represent a bit of a disadvantage for the virus,” she says. “We’re going to have to wait and see what this structural change in the way it binds will eventually mean.” But the fact that the vaccine still stimulates a good antibody response is encouraging that it will protect against BA.2.86 as well. The FDA is expected to make a decision in September about which strain the updated COVID-19 vaccine should target, although it’s widely expected that the shot will focus on XBB.1.5\. And so far, Moderna at least is “reassured in terms of the ability of \[that\] vaccine to improve protection against even BA.2.86,” says Miller. ## Transcript What I can say is that we are prepared for the fall. We believe that we're prepared for the fall, we believe that we are in a better position than we've ever been to come back home at 19th. And that's because of the work that the president has done. You heard from FDA, you heard from CD, scdc, pardon me, who said that there's going to be a new vaccine is going to be available in mid-september and look because of the work that this Administration has done with the leadership. With this President, we have been able to put together a comprehensive way to deal with this pandemic to deal with covid-19 and we have put forth multiple tools to do that and vaccine. Clearly is one of that when it comes to informing the American people about these vaccines about the different tools at this press, this is President and his administration has put forward, we have really put informing Americans up as a priority and so will continue to do that. We know that that covid-19 vaccine nations are the safest to protect to protection for avoiding hospitalization long-term health. And death. And that is why we are going to continue to encourage Americans to stay up-to-date on their vaccines. We believe we are in the strongest position yet in the strongest position. Yet to deal with covid-19 multiple times at this at this point and, you know, any any anything that we might see in the fall or in the winter. That's because safe and updated vaccines that will be available in mid-september Wylie available at home. Covid test, right? I talked about the different tool that the Administration has been able to to put forward a widely available effective treatments what which can reduce the risk of severe illness hospitalizations and deaths. And we are also going to encourage, we are going to encourage Americans to get their updated covid-19 vaccine in addition to their annual flu shot. Let's not forget that is important for Americans to get and an RSV immunization for people over 60. And for infants, that is something that we're going to continue to make fairy Are two Americans across across the country as it relates to, any uptick nashly, while the CDC is reporting an increase in infections and hospital and hospital is at the hospital admissions over remains low. But again, we believe that we are in a good position on the strongest position that we have been in the past 3 years or so, not to deal to deal with covid-19. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6311210/moderna-covid-vaccine-ba286-variant/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6311210/moderna-covid-vaccine-ba286-variant/"},"headline":"Moderna Says Its New COVID-19 Vaccine Protects Against the BA.2.86 Variant","datePublished":"2023-09-06T16:09:53.000Z","dateModified":"2026-08-04T07:50:56.435Z","description":"The vaccine wasn’t designed to target this latest variant, but still prompts a strong immune response, the company reports.","url":"https://time.com/6311210/moderna-covid-vaccine-ba286-variant/","keywords":["COVID-19"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5da9b9afeb8adb10/698a4012011682004998364d/GettyImages-1348139157.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt5da9b9afeb8adb10/698a4012011682004998364d/GettyImages-1348139157.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Hand in blue medical gloves holding a syringe and vaccine vial with Covid 19 Vaccine Booster text, for Coronavirus booster shot.","caption":"Hand in blue medical gloves holding a syringe and vaccine vial with Covid 19 Vaccine Booster text, for Coronavirus booster shot.","creditText":"iStockphoto—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/covid-19/","name":"COVID-19"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/6311210/moderna-covid-vaccine-ba286-variant/","name":"Moderna Says Its New COVID-19 Vaccine Protects Against the BA.2.86 Variant"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"White House Says the Administration is \"Prepared for the Fall\" When it Comes to Combatting COVID","description":"White House Press Secretary Karine Jean-Pierre said on Monday that the administration is \"prepared for the Fall\" when it comes to dealing with a rise in COVID-19 infections.","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/A4u2hWYq/poster.jpg?width=720","uploadDate":"2023-08-29T17:26:59.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/A4u2hWYq.m3u8","embedUrl":"https://time.com/6311210/moderna-covid-vaccine-ba286-variant/","duration":"PT2M25S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/6311210/moderna-covid-vaccine-ba286-variant/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
