美國兒科學會(American Academy of Pediatrics)和兒童醫院協會(Children’s Hospital Association)于9月20日發布的一份報告顯示,隨著更具傳染性的德爾塔變種病毒繼續在返校學生中傳播,感染新冠病毒的兒童數量正在呈“指數級”上升。
美國兒科學會報告說,在截至9月16日的過去一周內,有近226000例新的兒童病例,這是自新冠疫情開始以來一周內第三高的兒童病例數。上周報告的所有病例中,兒童占25.7%,盡管自新冠疫情爆發以來,兒童僅占所有新冠肺炎病例的15.7%,占美國人口的22.2%。
上周報告的兒童病例數較7月15日至22日期間報告的約39000例增加了480%,這進一步表明在夏季的最后幾個月里,新冠疫情的形勢逐漸嚴峻。
美國兒科學會在報告中說:“初夏時期,新冠肺炎病例數下降之后,兒童病例數呈指數級增長,在過去四周內超過92.5萬例。”自從新冠疫情流行以來,總共有550萬名美國兒童的新冠病毒檢測呈陽性。
目前,美國只有12歲及以上的兒童才有資格接種新冠疫苗。不過,因為輝瑞(Pfizer)的疫苗和BioNTech的疫苗預計將為更年幼的兒童申請緊急批準,5歲至11歲的兒童也將擁有接種疫苗的資格。
因為美國各州和學區的關于強制戴口罩的政策各不相同并且德爾塔變種病毒繼續感染人群,衛生官員仍然擔心今年秋天新冠病毒會在教室里的兒童群體中進一步傳播。白宮首席醫療顧問安東尼·福奇博士于一個多星期前在倫敦衛生與熱帶醫學院(London School of Hygiene and Tropical Medicine)主辦的一次演講中表示,他擔心德爾塔變種病毒對未接種疫苗的兒童造成影響。
“我們的醫院幾乎不堪重負。目前有很多孩子在醫院里。”福奇說。“盡管相對而言,與成年人相比,他們的病情沒有那么嚴重,但死于新冠病毒的兒童比死于流感的兒童更多,我們卻只給兒童接種了流感疫苗。”
雖然兒童因為新冠肺炎而住院的比例確實高于初夏時期,但在報告數據的24個州中,兒童病例僅占新冠肺炎患者住院總人數的1.6%至4.2%。
總體而言,0.1%至2%的兒童病例住院,在報告中各州的數據顯示,兒童病例占新冠肺炎死亡病例的比例不超過0.25%。相對而言,該病毒對兒童的長期影響仍然未知。
美國兒科學會在報告中說:“目前,新冠疫情導致的嚴重疾病在兒童中似乎不常見。然而,我們迫切需要收集更多關于新冠疫情對兒童的長期影響的數據,包括對感染新冠病毒的兒童的身體健康以及對兒童情緒和心理健康的影響。”
兒童疫苗的時間表
輝瑞和BioNTech公司正在推動美國和歐盟(European Union)的監管機構迅速批準它們針對5歲及以上兒童的新冠疫苗。BioNTech公司的首席執行官烏古爾·薩欣在一份聲明中說,對這一群體的測試已經得出了與老年群體一致的結果。
正如《財富》雜志的資深撰稿人戴維·梅耶在9月21日的報道中所述,制藥商在對幼兒進行疫苗試驗時,必須考慮幾個因素,其中之一就是接種劑量。以輝瑞和BioNTech公司的疫苗為例,5歲至11歲的兒童將接種10微克的新冠疫苗,這是12歲及以上兒童接種量的三分之一。
這些公司還表示,它們希望“最快在今年第四季度”提供新冠疫苗對2歲至 5歲,以及6個月至2歲人群的安全性和有效性的測試結果。(財富中文網)

COVID cases among children are rising “exponentially,” according to a report released by the American Academy of Pediatrics (AAP) and the Children’s Hospital Association on September 20, as the more contagious Delta variant continues to wreak havoc with students returning to school.
The AAP reported nearly 226,000 new child cases over the past week ending Sept. 16—the third-highest number of child cases in a week since the pandemic began. Children accounted for 25.7% of all cases reported last week, despite representing just 15.7% of all COVID cases since the pandemic began and making up 22.2% of the U.S. population.
Further highlighting how much the situation has worsened over the final months of summer, last week’s pediatric cases mark a 480% increase over the roughly 39,000 new cases among children reported during the week of July 15 to 22.
“After declining in early summer, child cases have increased exponentially, with over 925,000 cases in the past 4 weeks,” the AAP said in the report. In total, 5.5 million U.S. children have tested positive for COVID-19 since the beginning of the pandemic.
Currently, only children ages 12 or older are eligible to receive the COVID vaccine in the United States. However, that eligibility could soon expand to ages 5 to 11, as Pfizer and BioNTech are expected to file for emergency approval for younger children.
Health officials remain concerned over further spread among children in the classroom this fall—with mask mandate policies varying by state and school district—while the Delta variant continues to infect people at high rates. White House chief medical adviser Dr. Anthony Fauci, when speaking at a lecture hosted by the London School of Hygiene and Tropical Medicine a little over a week ago, expressed concern over the impact the virus is having on children who remain unvaccinated.
“We are almost overrun. We have a lot of children in hospitals now,” Fauci said. “So even though relatively speaking, compared to an adult they don’t get as seriously ill, we have lost more children from SARS-CoV-2 than we ever lose for influenza—and we vaccinate children against influenza.”
While child hospitalizations due to COVID are indeed occurring at a higher rate than they did early in the summer, kids have made up only between 1.6% and 4.2% of overall COVID hospitalizations among the 24 states that reported data.
Overall, between 0.1% and 2% of pediatric cases result in hospitalization, and children have accounted for no more than 0.25% of COVID deaths among the states that reported that data. Longer-term effects of the virus on children are still relatively unknown.
“At this time, it appears that severe illness due to COVID-19 is uncommon among children,” the AAP said in the report. “However, there is an urgent need to collect more data on longer-term impacts of the pandemic on children, including ways the virus may harm the long-term physical health of infected children, as well as its emotional and mental health effects.”
Timelines on vaccines for kids
Pfizer and BioNTech are pushing for quick approval from U.S. and European Union regulators of their COVID vaccine for kids age 5 and older. BioNTech CEO Ugur Sahin said in a statement that tests on that group had produced results consistent with those in older populations.
As Fortune senior writer David Meyer reported on September 21, there are several considerations that the drugmakers have had to take into account when trialing the vaccine in younger children, one of which is the amount that is to be administered. In the case of Pfizer and BioNTech’s vaccine, kids between the ages of 5 and 11 will get 10-microgram doses, which is a third of the amount that people age 12 and older get.
The companies said they are also hoping to provide results on COVID vaccine safety and effectiveness for the 2- to 5-year-old and 6-month to 2-year-old cohorts “as soon as the fourth quarter of this year.”
