Covid-19疫苗可能需要很長時間。 一些科學家提出了一個有爭議的計劃，可以使我們更快地完成一項計劃。 成為視頻實驗室會員！ http://bit.ly/video-lab每天都有成千上萬的人死於Covid-19，疫苗被認為安全有效的越早越好。 但是疫苗開發是一個漫長的過程，不容易匆忙完成，部分原因是測試任何疫苗的最後一步：III期試驗。 第三階段需要成千上萬的志願者，每人都接受安慰劑或實驗疫苗。 問題出在下一部分：疫苗開發人員必須等到統計上數量龐大的疫苗開發人員才能正常生活，最終受到自然感染。 這可能需要數年。 為了加快速度，一些流行病學家和科學家呼籲進行一項稱為「人類挑戰試驗」的試驗，在該試驗中，已接種疫苗的受試者被故意感染。 這不是一個新概念； 人類挑戰試驗已被用來開發疫苗或治療多種疾病的疫苗，例如霍亂，傷寒，瘧疾，流感和普通感冒病毒。 但是，使Covid-19與這些疾病區分開來的原因是，目前沒有有效的治療方法。 因為它太新了，所以我們也沒有完全意識到它對健康的長期影響。 與其他人體挑戰試驗不同，Covid-19挑戰試驗將帶來嚴重疾病甚至死亡的風險。 由於存在這些風險，Covid-19挑戰性試驗僅限於年輕人和健康者，他們受到傷害的風險最低。 但是，倫理學之外還有其他問題。 在實驗室環境中人為感染是否可以提供有關如何預防自然感染的有用信息？ 僅針對年輕人和健康人群進行的研究是否會產生對所有人都有效的疫苗？ 鑒於某些疫苗已經在其III期試驗中進行了很長時間，因此人類挑戰試驗在這一點上是否有好處？ 儘管目前尚未計划進行Covid-19人體挑戰試驗，但來自近150個國家/地區的30,000多人已經表示，如果有機會，他們將自願參加一項試驗。 問題是，我們應該讓他們嗎？ 注意：此文章的標題已更新。 先前的標題：您願意自願獲得Covid-19嗎？ 進一步閱讀：1DaySooner是基層組織，它招募志願者進行人類挑戰試驗的可能性：https：//1daysooner.org/有關Vox關於人類挑戰研究的更多報道：https：//www.vox.com/future-perfect / 2020/5/20/21258725 / covid-19-human-challenge-trials-vaccine-update-sars-cov-2有關疫苗開發的道德和可接受性問題的更多信息：https://medium.com/oxford-大學/具有挑戰性的情況-我們需要國際指南-人類感染-研究-688051c869f9有關其他疾病的挑戰研究史：https://www.sciencemag.org/news/2016/05/studies -故意感染人-疾病-導致bug-上升-關於傷寒疫苗的報道，我們在視頻中提到：https：//www.nytimes.com/2017/09/28/health/typhoid-vaccine- trial.html有關牛津大學關於人類挑戰試驗的聲明的報道：https://www.theguardian.com/science/2020/jul/16/coronavirus-vaccine-oxford-team-volunteers-lab-control -human-challenge-trial Vox.com是一個新聞網站，可幫助您消除噪音並了解引起頭條新聞的真正原因。 請訪問http://www.vox.com。 觀看完整的視頻目錄：http://goo.gl/IZONyE在Facebook上關注Vox：http://goo.gl/U2g06o或Twitter：http://goo.gl/XFrZ5H。

  1. Access to clear, reliable information has never been more important than today. But great journalism is expensive and ads alone aren』t enough to support it. If you are in a position to do so, please join a community of nearly 20,000 people who believe in the public value of information, and support Vox with a financial contribution. It』s a great way to help keep our journalism, including the video explainers you love, free for all. http://www.vox.com/contribute

  4. Would there be a connection why 60,942,033 babies were aborted in the US since 1973 and the Covid 19 vaccine having aborted baby tissue as one of the ingredients?

  5. You really want to do this, Vox? You're going to alarm all of the anti-vaxers and covid-hoaxers. Even the title of this video is going to seed a lack of confidence in the medical community. Also, testing a larger amount of participants doesn't actually help speed things up because it can't record long-term effects. THIS WOULD NOT WORK.

  15. i mean there ARE covid treatments. death rate is down in a lot of places because of that. we know a lot more about ventilators and such. i say if people are willing to volunteer, go for it

  24. Me and my husband are in our twenties but we both have several underlying health conditions. Bless the people who are willing to take this risk for those of us who can』t. Thank you.

  26. Another problem is that these companies will make lots of profit from these vaccines over the back of the often poor people that took considerable risk participating in the trials.

  27. It was right in front of us! Let's grab all people on death row or life in prison and let them do something good for once in their lives. As much as I don't want to admit it, russia has the right idea when it comes to doing vaccine tests.

  28. I got COVID (asymptomatic) and keep trying to find studies that will take me as a volunteer (obviously not for vaccines due to having antibodies, but i'd love to help out with plasma research or something). You'd think they'd be everywhere, but they're hard to find.

  34. At the end where they talk about how brave these volunteers are I just started crying. Don't know what it is but the idea that someone would take this on means so much to me as someone who wouldn't participate because despite being young, I have asthma. Thanks for reminding of the good people in the world.

  38. I guess it's too unethical to recruit the elderly and the sick for the human challenge trial. Human challenge trial on young, healthy adults is pointless so why even do that? COVID-19 is very unique in that it's only "deadly" to the elderly and the ones with pre-existing conditions so we should focus on those groups…not the young and healthy adults.
