根据实时数据汇编，随着新冠肺炎大流行席卷全球，全球已有超过500万人死于该疾病，其中包括超过75.5万美国人约翰·霍普金斯大学系统科学与工程中心。

根据美国疾病控制和预防中心的数据，只有68.3%的12岁及以上的美国人完全接种了新冠肺炎疫苗美国疾病控制和预防中心。

一位了解情况的政府官员告诉美国广播公司新闻，辉瑞可能最快在本周寻求食品药品监督管理局批准为18岁及以上的人接种冠状病毒疫苗加强剂。

美国疾病控制和预防中心建议某些患者在第二次注射后六个月注射辉瑞强化疫苗。

那些符合条件的患者包括老年人、患有某些疾病的成年人以及在暴露于新冠肺炎风险更大的环境中工作的成年人。

一位了解运输安全管理局计划的人士告诉美国广播公司新闻，尽管由于联邦政府的疫苗授权，成千上万的运输安全管理局工作人员可能会被解雇，但感恩节航班不会受到影响。

联邦工作人员必须在11月22日之前接种疫苗，否则将面临解雇。消息人士称，截止日期后，未完全接种疫苗的美国运输安全管理局员工将被要求与主管进行讨论，并接受接种疫苗的咨询和教育。

消息人士称，如果工人在第一次会议后没有接种疫苗，他们将收到警告。消息人士称，警告发出后，工人将被解雇。

三周前，美国运输安全管理局称其40%的员工没有接种疫苗。该机构尚未提供最新数字。

拜登参观儿童疫苗接种诊所

第一夫人吉尔·拜登和医务总监·维韦克·穆尔西博士参观儿童疫苗接种诊所周一在弗吉尼亚州麦克林的富兰克林·谢尔曼小学，推广儿科疫苗接种。

拜登说:“疫苗是保护你的孩子免受新冠肺炎侵害的最佳方式。“它经过了彻底的审查和严格的测试，它是安全的，是免费的，这个国家的每个5岁及以上的孩子都可以使用。”

富兰克林·谢尔曼小学是1954年第一所接种脊髓灰质炎疫苗的学校。

介绍拜登的六年级学生埃弗雷特·蒙森(Everett Munson)说，“我很兴奋能接种疫苗，因为现在我可以去看望我的堂兄弟和祖父了。...我期待着去一些地方，而不用担心我会得到COVID并把它给我的家人、朋友或老师。”

蒙森还提出了一个受学校历史启发的想法。

“也许我们甚至应该从富兰克林·谢尔曼的脊髓灰质炎疫苗中吸取一个想法:每个人都应该在注射后得到冰淇淋，”蒙森说。

根据美国儿科学会和儿童医院协会的每周报告，美国上周有10.7万例儿科病例，在连续八周下降后有所上升。

但这仍远低于9月初记录的大流行高峰——一周内25.2万例儿童病例。

上周，儿童占病例的24%。儿童占美国人口的22.2%。

大约45.8%的12至17岁青少年已经完全接种疫苗。

这两个组织在报告中写道，新冠肺炎导致的严重疾病在儿童中仍然“不常见”。然而，AAP和CHA继续警告说，迫切需要收集更多关于大流行对儿童的长期后果的数据，“包括病毒可能损害受感染儿童长期身体健康的方式，以及它对情绪和精神健康的影响。”

COVID-19 live updates: Pfizer to seek approval for adult boosters: Source

As the COVID-19 pandemic has swept the globe, more than 5 million people have died from the disease worldwide, including over 755,000 Americans, according to real-time data compiled byJohns Hopkins University's Center for Systems Science and Engineering.

Just 68.3% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from theU.S. Centers for Disease Control and Prevention.

Pfizer is likely to seek authorization from the Food and Drug Administration for a coronavirus vaccine booster shot for people 18 and older as soon as this week, a government official with knowledge of the situation told ABC News.

The U.S. Centers for Disease Control and Prevention recommended the Pfizer booster shot for certain groups of patients six months after their second dose.

Thoseeligible patientsinclude seniors, adults with certain medical conditions and adults who work in environments that put them at greater risk for exposure to COVID-19.

Despite a looming threat that thousands of Transportation Security Administration workers could be terminated over the federal government’s vaccine mandate, Thanksgiving flights won’t be affected, a person with knowledge of the agency’s plans told ABC News.

Federal workers have until Nov. 22 to get vaccinated or face termination. After the deadline, TSA employees who are not fully vaccinated willget called to have a discussion with supervisors and be counseled and educated on getting vaccinated, the source said.

If workers do not get vaccinated following the first meeting, they will receive a warning, according to the source. Following the warning, workers will be subject to termination, the source said.

Three weeks ago, the TSA said 40% of its workforce was unvaccinated. The agency hasn't provided updated numbers.

First lady Jill Biden and Surgeon General Dr. Vivek Murthyvisited a children's vaccination clinicMonday at Franklin Sherman Elementary School in McLean, Virginia, to promote pediatric vaccinations.

"The vaccine is the best way to protect your children against COVID-19," Biden said. "It’s been thoroughly reviewed and rigorously tested, it’s safe, it’s free, and it’s available for every child in this country, 5 and up."

Franklin Sherman Elementary was the first school to administer the polio vaccine in 1954.

Sixth-grader Everett Munson, who introduced Biden, said, "I'm excited to be vaccinated because now I'll be able to visit my cousins and grandfather. ... I'm looking forward to going places without worrying that I could get COVID and give it to my family, friends or teachers."

Munson also pitched an idea inspired by the school's history.

"Maybe we should even take an idea from the polio vaccine at Franklin Sherman: Everyone should get ice cream after their shots," Munson said.

The U.S. saw 107,000 pediatric cases last week, an uptick following eight consecutive weeks of declines, according to a weekly report from the American Academy ofPediatrics and the Children’s Hospital Association.

But this is still much lower than the pandemic peak -- 252,000 child cases within one week – which was recorded in early September.

Last week, children accounted for 24% of the cases. Children make up 22.2% of the U.S. population.

Approximately45.8%ofadolescents ages 12 to 17 have been fully vaccinated.

Severe illness due to COVID-19 remains "uncommon" among children, the two organizations wrote in the report.However, AAP and CHA continue to warn that there is an urgent need to collect more data on the long-term consequencesofthe pandemic on children, "including ways the virus may harm the long-term physical healthofinfected children, as well as its emotional and mental health effects."
