美國(guó)前衛(wèi)生總監(jiān):新冠疫情在2022年之前不會(huì)結(jié)束

Maria Aspan 2020-08-05
需要至少70%的人口接種才能達(dá)到針對(duì)新冠病毒的“群體免疫”,。

美國(guó)前衛(wèi)生總監(jiān)于本周二發(fā)出警告,即便新型冠狀病毒肺炎的疫苗研發(fā)競(jìng)賽很快會(huì)決出勝者,,我們也不能指望這場(chǎng)大流行病會(huì)在2022年之前結(jié)束,。

“我認(rèn)為我們?cè)?021年還無(wú)法在表面上恢復(fù)到疫情之前的狀態(tài),” 維維克·默西在參加一場(chǎng)由美國(guó)嘉年華郵輪集團(tuán)和世界旅游及旅行業(yè)理事會(huì)聯(lián)合舉辦的線上虛擬大會(huì)中說(shuō)道,,他曾在美國(guó)前總統(tǒng)奧巴馬的任期內(nèi)擔(dān)任衛(wèi)生總監(jiān),。

世界衛(wèi)生組織的數(shù)據(jù)顯示,目前有超過(guò)160種針對(duì)新冠肺炎的疫苗正在研發(fā),,其中約有25種正在進(jìn)行人體臨床試驗(yàn),。少數(shù)疫苗已經(jīng)進(jìn)入三期臨床試驗(yàn),已有數(shù)千人接種,,這些疫苗有的由牛津大學(xué)與阿斯利康制藥公司共同研發(fā),,有的是莫德納生物科技公司與美國(guó)國(guó)立衛(wèi)生研究院的合作成果,還有的來(lái)自數(shù)家中國(guó)機(jī)構(gòu),。

不過(guò),,此前領(lǐng)導(dǎo)美國(guó)抗擊埃博拉和寨卡疫情的默西警告稱:“即使是在樂觀情況下,我們也可能要到2021年中才會(huì)看到疫苗大規(guī)模推廣,?!?/p>

疫苗的推廣本身也面臨著挑戰(zhàn),近些年來(lái)美國(guó)的反疫苗情緒日益增長(zhǎng),,他們對(duì)新研發(fā)的新冠肺炎疫苗也抱著懷疑態(tài)度,,這些困難都需要克服。所以,,即便最后面世的疫苗百分百有效,,默西稱“這種可能性極低”,也需要至少70%的人口接種才能達(dá)到針對(duì)新冠病毒的“群體免疫”,。

“我們有可能在2021年底做到這些,,為70%的人口接種疫苗嗎?那我們大概要完成歷史上最為成功的疫苗接種工作才行,,”默西說(shuō)道,。“這能做到嗎,?怎么說(shuō)呢,,凡事都有第一次,。”

與其他公共衛(wèi)生專家的說(shuō)法相比,,他更為直接地指出了形勢(shì)的嚴(yán)峻,。盡管美國(guó)一些城市和州重新展開了疫情防控工作,但新冠肺炎感染人數(shù)仍在激增,。美國(guó)國(guó)家過(guò)敏癥和傳染病研究所所長(zhǎng)福奇上周承認(rèn),,疫情“目前基本看不到盡頭”,它也永遠(yuǎn)不會(huì)被根除,。

不過(guò)談到恢復(fù)常態(tài)的速度時(shí),,他比默西要略微樂觀,?!叭绻辛己玫墓残l(wèi)生措施、一定程度的群體免疫和有效的疫苗,,我希望我們能研發(fā)成功并對(duì)此謹(jǐn)慎樂觀……我們會(huì)控制住局勢(shì)的,,”福奇上周在面對(duì)全球結(jié)核病新藥研發(fā)聯(lián)盟的線上采訪時(shí)說(shuō)道?!拔也淮_定是今年還是明年,。”

默西本周二在全球科學(xué)峰會(huì)上發(fā)表了講話,,他的預(yù)測(cè)對(duì)于主辦方來(lái)說(shuō)或許不是好事,。這一活動(dòng)由旅游業(yè)貿(mào)易組織世界旅游及旅行業(yè)理事會(huì)和嘉年華郵輪集團(tuán)合辦,后者迫切希望郵輪業(yè)務(wù)能在2022年之前恢復(fù)正常運(yùn)營(yíng),。

嘉年華郵輪集團(tuán)的CEO阿諾德·唐納德本月早些時(shí)候曾充滿信心地表示,,集團(tuán) “即便是在零收入的情況下也能撐到明年年底”。不過(guò),,他的公司及其競(jìng)爭(zhēng)對(duì)手也在號(hào)召公共衛(wèi)生專家,,希望他們能讓乘客放心,早日登上安全的郵輪,。(如果得到政府允許的話,,美國(guó)疾病控制與預(yù)防中心月初再次延長(zhǎng)了針對(duì)郵輪公司的“禁航令”,責(zé)令其至少在9月30日之前不得在美國(guó)水域內(nèi)恢復(fù)客運(yùn)服務(wù),。)

其他旅游業(yè)高管也發(fā)出提醒,,他們預(yù)計(jì)這場(chǎng)大流行病對(duì)旅游業(yè)的傷害會(huì)持續(xù)到2022年甚至更久。美國(guó)達(dá)美航空公司CEO埃德·巴斯蒂安警告稱,,航空旅行可能需要“兩年或更長(zhǎng)時(shí)間才能推動(dòng)可持續(xù)復(fù)蘇”,。

在這場(chǎng)由嘉年華郵輪集團(tuán)CEO唐納德和世界旅游及旅行業(yè)理事會(huì)CEO格洛麗亞·格瓦拉共同主持的線上虛擬大會(huì)上,默西和其他演講者并沒有花費(fèi)太多時(shí)間專門處理郵輪的問題,。唐納德在大會(huì)結(jié)束之際表示,,他希望讓這次活動(dòng)“只關(guān)乎科學(xué),,不推廣郵輪或旅游”,但他也補(bǔ)充說(shuō),,許多與會(huì)發(fā)言的科學(xué)家正和嘉年華郵輪集團(tuán)針對(duì)其健康及安全標(biāo)準(zhǔn)進(jìn)行合作,。

“戴口罩,勤洗手,,保持安全,,去做檢測(cè),”他總結(jié)道,,“世界就會(huì)變得更加美好,。”(財(cái)富中文網(wǎng))

Even if the race for a COVID-19 vaccine has a winner soon, don’t expect the pandemic to end before 2022, a former U.S. surgeon general warned Tuesday.

“If the goal is to return life to some semblance of what it was like pre-pandemic, I don't see that happening in 2021,” Vivek Murthy, a surgeon general under President Obama, said during a virtual event organized by cruise operator Carnival Corp. and the World Travel & Tourism Council.

More than 160 efforts are underway to develop vaccines for COVID-19, according to the World Health Organization, with about 25 being tested on humans in clinical trails. A handful of vaccines—including those developed by the University of Oxford with AstroZeneca, Moderna Therapeutics with the National Institutes of Health, and several Chinese entities—have advanced to the Phase III stage of being tested on thousands of patients.

But Murthy, who previously led U.S. responses to the Ebola and Zika outbreaks, cautioned that “even in an optimistic scenario, it would likely be closer to mid-2021 that we would see vaccines starting to be distributed at scale.”

That distribution will bring its own challenges, including the need to overcome Americans’ growing anti-vaccine sentiment of recent years and their new skepticism about the vaccines being developed for COVID-19. So even if a final vaccine is 100% effective—“which would be extremely rare,” Murthy pointed out—at least 70% of the population would need to be vaccinated in order to reach “herd immunity” against the coronavirus.

“Is there a chance we could do this all and vaccinate 70% of the population by the end of 2021? I think it would take the best vaccination campaign that we've ever assembled in the history of the world to do that,” Murthy said. “Could it be done? Well, there's a first time for everything.”

It was one of the more bluntly grim timelines offered by public health experts in recent days, as U.S. infections of COVID-19 surge in the face of various city and state efforts to reopen. Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, last week acknowledged that there is “so far essentially no end in sight” to the pandemic and that it would never be fully eradicated.

But he was also slightly more optimistic than Murthy about the speed of a return to normal. “With a combination of good public health measures, a degree of global herd immunity, and a good vaccine, which I do hope and feel cautiously optimistic that we will get…we will get control of this,” Fauci told the TB Alliance during a virtual interview last week. “Whether it’s this year or next year, I’m not certain.”

Murthy’s prediction was probably not welcome news to the hosts of the Global Scientific Summit, where he spoke on Tuesday. The event was put together by the World Travel & Tourism Council (WTTC), a travel industry trade group, and Carnival, a company that’s desperately hoping that the cruise business somehow manages to resume normal operations before 2022.

CEO Arnold Donald said earlier this month that he is confident Carnival can survive “into late next year, even in a zero-revenue scenario.” But his company and its competitors are also mustering panels of public health experts to reassure passengers that it will be safe to board cruise ships long before then. (If, that is, governments allow it. Earlier this month, the U.S. Centers for Disease Control and Prevention extended its “no sail” order for cruise companies for a second time, barring them from resuming passenger operations in U.S. waters until at least Sept. 30.)

Other travel executives have warned that they expect the pandemic to continue hurting their industry until 2022, or longer. Earlier this month, Delta CEO Ed Bastian warned that “it could be two years or more before we see a sustainable recovery” in air travel.

Murthy and other speakers at Carnival’s virtual event, which was cohosted by Donald and WTTC CEO Gloria Guevara, did not spend much time addressing cruises specifically. Donald ended the program by saying that he had wanted to keep the event to “just science, and not make it promotional for cruise or travel,” but added that many of the scientists who spoke during the event were working with Carnival on its health and safety standards.

“Wear your mask, wash your hands, stay safe, get tested,” he concluded, “and the world will be a better place.”
