The Biden administration is eyeing mid-September for the rollout of updated COVID-19 vaccines, according to Food and Drug Administration and Centers for Disease Control and Prevention officials.
“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.
C | 在这位老杭州人的心中，西湖的山水是童年一份特殊的印记，“我们小时候到湖里抓鱼、摸虾，退休了之后没事儿就过来转转，对这里特别有感情。”洪先生说，自打西湖莲蓬义卖的第一年以来，自己就参与了，此后年年到场，“尝过之后就会知道，西湖长出的莲子和莲蓬味道和其他地方的不一样，荷叶还可以用来泡茶，香气扑鼻。
D | ”昨天的1号小票，被准高三学生操睿收入囊中，小姑娘骑了1小时的车，凌晨4点多到达现场，“去年我也来了，今年比预想中的人少一点，没想到真的拿到1号，希望能借着好运给接下来的高三生活开一个好头。”早上8点30分，义卖活动准时开启，市民们按照号码牌有序排队，“爱心莲莲”套餐还是老规矩：10元钱能够买到3个莲蓬和5张荷叶，每人限购一份，售完即止。领到爱心套餐的市民都迫不及待地打开袋子，满眼欣喜地展示“战利品”：有人第一时间拍照分享，有人直接剥开莲蓬品尝果实的清甜，还有小朋友顽皮地举起荷叶，当成帽子……每个人的脸上都洋溢着由衷的快乐。西湖景区水域管理处水生植物养护班班长俞阳洋说，这些带着“鲜气儿”的爱心套餐都是西湖养荷人凌晨4点采摘下来的，“为了确保荷花健康和美态，养荷人会一根根疏理，然后将这些带着露水与清香第一时间送到微笑亭。”俞阳洋透露，荷花喜欢阳光，由于台风刚过以及近期阴雨影响，部分荷叶叶面上可能有斑点等，样子没那么完美。同时西湖荷花属于观赏性“花莲”，莲蓬产量等都比不了专供食用的“子莲”。所以每天义卖数量将根据天气和荷花生长情况而定，还请大家理解。今年的爱心义卖从昨天开始将持续至8月下旬。其间，每周一到周五上午7时，在柳浪闻莺微笑亭发放当日号码牌；8点30分至9点凭号码牌当场购买，过时号码作废；请自备零钱，或使用支付宝支付。如遇雨天或双休日，义卖活动暂停，所有的义卖善款将全部捐给慈善机构。需要再次提醒市民朋友，天气炎热，请大家注意防暑，根据自身状况前往，文明有序购买。
