美國專家考慮用新冠康復者的血液做短期疫苗
Blood from recovered coronavirus patients could be used in a vital stop-gap treatment to help protect humanity from the COVID–19 pandemic currently spreading around the world, researchers propose.
研究人員建議，目前新冠肺炎在全球傳播，新冠康復者的血液可以被用於重要的短期治療，來幫助人們免受新冠病毒的影響。In a new paper, infectious disease experts explain how viral antibodies, contained in the blood serum of patients who have already recovered from the new coronavirus, could then be injected into other people, offering them short-term protection.
一篇新論文中，傳染病專家解釋了新冠肺炎康復者的血清中的病毒抗體是如何被注射進他人體內，爲他們提供短期保護的。This long-established medical remedy – called passive antibody therapy – dates back to the late 19th century, and was widely used during the 20th century to help stem outbreaks of measles, polio, mumps, and influenza.
這種歷史悠久的醫學療法被稱爲被動抗體療法，可以追溯到19世紀末，在20世紀被廣泛用來幫助遏制麻疹、脊髓灰質炎、腮腺炎和流感的爆發。
Much as it aided us before, it could be a crucial and practical tool now in the fight against COVID–19, a team from Johns Hopkins University argues in the new study, adding that antibody therapies can also be made available with urgency.
約翰斯·霍普金斯大學的團隊在這項新研究中認爲，之前這種療法給了我們很大幫助，現在在對抗新冠肺炎的治療中也能成爲重要而且實用的療法。他們還補充說抗體療法也可以緊急提供。"Deployment of this option requires no research or development," says immunologist Arturo Casadevall.
免疫學家Arturo Casadevall說：“採用這種方法不需要進行研究或開發。”"It could be deployed within a couple of weeks since it relies on standard blood-banking practices."
“幾周內就能實現，因爲它依賴的是標準血庫操作規程。”For the treatment to work, recovered coronavirus patients would need to donate their blood after recovering from COVID–19 and while still convalescing from the disease. During this phase, the blood serum would contain high amounts of natural antibodies produced to combat the SARS-CoV–2 virus.
爲了起到治療作用，康復的新冠肺炎患者需要在病情好轉之後的康復期內獻血。在這一時期，血清中產生的對抗新冠病毒的自然抗體的含量很高。
