Biden Administration Eyes Mid-September for New COVID-19 Booster Shot Rollout_我的网站

A |     8月25日消息，根据B站UP主芝士华莱士的最新实测，国产长鑫存储颗粒已能稳定运行在DDR5-8000频率，且在部分生产力及游戏测试中，其性能表现已与海外主流的海力士新旗舰M-die方案高度接近。     此次测试硬件平台采用英特尔酷睿Ultra 7 270K Plus处理器，搭配微星Z890M GAMING PLUS WIFI主板，显卡选用七彩虹GeForce RTX 5080 Ultra WOC，并由1200W大功率电源驱动。

“Vaccination is going to continue to be key this year because immunity wanes and because the COVID-19 virus continues to change,” an official said on a call with reporters. “For those reasons, vaccines remain the best protection against hospitalization and death.”

It’s the first time that vaccines for all three of the major fall and winter viruses – flu, COVID-19 and respiratory syncytial virus – will be available.

The announcement comes as COVID-19 hospitalizations are increasing and the Biden administration hopes to get ahead of any potential fall or winter coronavirus wave with its vaccine campaign.

Moderna, Pfizer and Novavax have developed updated coronavirus vaccines that will target the XBB.1.5 strain, which was responsible for less than 5% of new infections in recent weeks, according to CDC data.

The dominant strain circulating now is EG.5 – nicknamed “eris” – that is causing over 20% of new cases.

Eris appears more transmissible and better able to evade immunity provided by vaccines and previous infection, according to the World Health Organization, but it hasn’t been associated with more severe disease.

Another variant to watch is BA.2.86, which quickly caught the attention of both WHO and the CDC. The highly mutated strain is likely not responsible for the recent rise in hospitalizations in the U.S., according to the CDC, but it is too soon to know the new strain’s transmissibility or severity.

Officials believe the updated shots will work against these strains.

“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,” one of the officials said.

The CDC’s committee of outside vaccine experts will meet in mid-September to recommend who should get the updated COVID-19 vaccines. The officials noted that for some people, including older or immunocompromised Americans, more than one shot per year may be needed.

。          在频率提升至8000MT/s后，长鑫方案的时序达到了CL40-52-52-128，海力士方案则采用了更紧的CL36-48-48-96。    基准测试显示，长鑫颗粒在8000MT/s下的内存读取带宽约为123.32GB/s，延迟为76.1ns，海力士方案读取带宽约为124.68GB/s，延迟为72.2ns。     两者带宽表现基本处于同一水平，海力士凭借更收紧的时序，在内存延迟方面取得领先。         在Geekbench 6测试中，长鑫8000MT/s方案获得24576分，与海力士同频率方案的24790分相比，差距仅为0.86%左右。     游戏性能上，在1080P分辨率测试中，在《彩虹六号：围攻X》中，两套8000MT/s内存的平均帧数仅相差5帧，差距不到1%。而在《刺客信条：黑旗重制版》中，两者的帧数表现基本处于同一水平线。         除此之外，在《使命召唤21》和《极限竞速：地平线5》等大作中，两套高频方案的帧数表现几乎完全一致，差距不足1FPS。          。
