What to Know About the New COVID-19 Booster Shots Planned for Next Month_我的网站

Coronavirus is on the rise in the U.S., prompting questions about when Americans can roll up their sleeves for the next COVID-19 vaccine.

COVID-19 hospitalizations have been increasing for six straight weeks. While levels remain far below previous coronavirus waves in the U.S., it’s still the first increase since winter, and it has even prompted the return of mask mandates for a handful of businesses and schools.

The Biden administration estimates that 97% of Americans ages 16 and over have some level of COVID-19 immunity through vaccination, previous infection or both. The number may sound promising – so why do people need another round of shots? Because that protection can fade in a matter of months, leaving individuals vulnerable to COVID-19 once again.

“Immunity is stronger today than at any other point in the outbreak,” Mandy Cohen, the director of the Centers for Disease Control and Prevention, said in a recent video statement. “That means we're moving towards COVID-19 being a more manageable illness with less severe illness. Having antibodies is like a shield, but we still need to be cautious because that protection does decrease over time.”

When Will the Shots Be Available?

Rollout of the shots is expected in mid-September, according to officials with the CDC and the Food and Drug Administration.

The shots from Moderna, Pfizer and Novavax first need authorization from the FDA. After that, the CDC’s committee of outside vaccine experts will gather to recommend who should be eligible for the shots. That meeting is scheduled for Sept. 12. Then, the CDC director must sign off on the recommendations before shots can be administered.

For undervaccinated or unvaccinated Americans – especially those who are at high risk for severe disease – Cohen says it might be best for them to roll up their sleeves now for the shots that are currently available.

“Those who have never been vaccinated and then some people who are older and at higher risk for a COVID infection might be best to get the existing COVID shot now and not wait,” Cohen said, noting that individuals should talk to their doctor first.

But Cohen added that “if you do get the current COVID-19 vaccine now or in early September, it could delay your ability to get this updated vaccine that's coming out in the middle of September.”

Will the Updated Boosters Work on New Coronavirus Variants?

The updated shots target XBB.1.5, which was responsible for less than 5% of new coronavirus infections in recent weeks.

The variant scene has changed significantly since the Biden administration advised vaccine makers to target the XBB strain in June. Now, EG.5, or “eris,” is the dominant strain circulating, causing over 20% of new cases.

But all the strains circulating are still descendants of omicron, so experts believe the shots will still protect against severe COVID-19 from the variants.

A Biden administration official told reporters last week, “FDA expects that once available, the updated vaccines will similarly provide protection against the most serious outcomes of the disease that may result from currently circulating variants.”

Additionally, experts are keeping a close eye on how BA.2.86, a new strain that is highly mutated, could affect the shots.

“The CDC is closely tracking a new variant which does have a number of changes or mutations that do make it distinct and different from the older versions of the virus,” Cohen said. “So we're working as fast as we can to understand this new variant and what impact it might have on how severe the COVID disease will get or how well our vaccines work against it.”

Will the New COVID-19 Shot Be Free?

Most Americans will receive the shot cost-free through their insurance. For uninsured Americans, the Biden administration is working on a program that will offer free shots at pharmacies. That program might not be available on the same day the shots are authorized but is expected to be up and running within a couple of weeks of the date.

Uninsured Americans will have immediate access to the shots for free at community health centers and individual providers as soon as they roll out.

How Many People Will Get a Booster Shot?

Historically, vaccine uptake decreases each time a new coronavirus shot is offered.

Just 17% of Americans as of May rolled up their sleeves for the latest round of shots offered. That’s a steep drop from the first shot, which saw 81% of the population roll up their sleeves.

But there are reasons to be hopeful that uptake of the shots could be higher this time around. A survey from KFF found that more than half of adults said they are likely to get another COVID-19 booster shot if it’s offered annually like the flu shot.

B | 8月26日讯在切尔西3-2战胜富勒姆后，英媒伦敦足球网撰文分析了蓝军的赛季首战。上赛季，除了一场比赛，切尔西在所有英超赛事中，跑动距离都不及对手，最终在场均跑动距离榜上排名垫底，然而，在新赛季的首轮比赛中，他们展现出了惊人的活力，跑动总距离超过了英格兰顶级联赛中的任何其他球队。周一晚，若昂·佩德罗在克拉文农场球场助蓝军击败富勒姆，并打入了英超历史上首轮比赛中最快的进球。随后，乔希·金在近角攻破罗伯特·桑切斯把守的大门，将比分扳平，不过，摩根·罗杰斯很快再次为切尔西确立了领先优势。下半场伊始，帕尔默将球从莱诺两腿之间送入网窝，在记分牌上留下了自己的名字。尽管随后贡萨洛·加西亚为阿韦洛亚执教的球队扳回一城，但蓝军顶住了压力，守住了胜果，拿下了宝贵的三分。切尔西渴望在四年内首次赢得英超新赛季揭幕战，而他们在跑动距离上的表现令人印象深刻，超过了英格兰顶级联赛的其他所有球队。蓝军全队跑动距离达到123.2公里，而富勒姆则为123.1公里，仅比对手少100米。周五晚，阿森纳在酋长球场迎战考文垂城时也展现了极高的跑动强度，全队跑动距离为119.8公里；赫尔城在MKM球场对阵曼联时，跑动距离也达到了118.5公里。伯恩茅斯同样不甘示弱，在阿提哈德球场挑战曼城的比赛中，全队跑动距离为117.9公里。首轮战罢，哈维·阿隆索麾下的这支球队在场均跑动距离榜上高居英超榜首——考虑到此前在马雷斯卡和罗塞尼尔执教时球队那种迟缓的表现，这无疑是一个巨大的进步。上赛季，蓝军在英格兰顶级联赛中几乎场场跑动距离都不如对手，直到2026年5月在安菲尔德球场对阵利物浦时，这一尴尬局面才得以改变。在那场比赛中，切尔西与红军战成1-1平，全队跑动距离为103.6公里，而红军则为102.9公里。然而，这种在体能投入上的改观并未持续太久，在赛季最后两场比赛中，蓝军在跑动距离上再次落后于托特纳姆热刺和桑德兰。

C | 尽管样本量还很小，且尚需时间验证这是否属于既定战术的一部分，但阿隆索显然在有意识地要求切尔西球员增加跑动距离。虽然跑动距离未必是衡量表现的绝对指标，但这位西班牙教头的前任们确实未能解决蓝军身体对抗能力不足的问题。2025年12月，马雷斯卡在接受记者采访时试图为球队跑动不足的情况进行辩解。在切尔西于埃兰路球场以1-3惨败给利兹联、且跑动总距离反而比对手少7公里的尴尬一幕发生前，这位意大利教练曾表示：“这可能也与对手针对我们的防守策略有关。

D | ”“具体来说，当对手采取高位逼抢时，意味着我们拥有更多空间，可以进行更多跑动，因为进攻空间更大了；而当对手选择退守时，就没有足够的空间供我们进行前插跑动。所以我个人认为，这取决于对手的战术表现。我认为这就是原因所在。

E | ”随后在2025年5月，马雷斯卡指出跑动不足是球队阵容构建的问题。他声称切尔西缺乏能够适应频繁攻守转换高强度身体要求的球员，因此当时球队才采取了节奏较慢、以控球为主的战术风格。

F | 这位前蓝军主帅说道：“我们并不擅长打攻守转换节奏的比赛。如果你回顾我们本赛季表现最差或陷入苦战的时刻，会发现这些比赛往往都演变成了频繁的攻守转换战。

G | ”罗塞尼尔也没能解决球队身体对抗能力不足的问题。

H | 在他被解雇前不久，这位前切尔西主帅曾指责球员缺乏“渴望、斗志和勇气”，暗示这是一个心理层面的问题。2026年4月，在阿梅克斯球场以0-3不敌布莱顿之后，罗塞尼尔对记者表示：“这关乎责任感。

I | 在合适的时候，我会维护球员，但我无法为那场比赛的表现辩护。”“那样的表现不代表这家足球俱乐部，也不符合我对球队的要求，这种情况必须改变。我感到麻木，同时也非常愤怒。我向来直言不讳，而那样的表现是不可接受的。我们丢掉的那些球是不可接受的，这一点我必须承担责任，”罗塞尼尔补充道。“我会审视全队及每位球员的表现，寻找一支我能信赖、能做好足球基本功的队伍。
