Century-Old Vaccine Investigated as a Weapon Against Coronavirus 彭博社 Bloomberg https://tinyurl.com/wcz3guf A vaccine that’s been used to prevent tuberculosis is being given to health-care workers in Melbourne to see if it will protect them against the coronavirus. The bacillus Calmette-Guerin, or BCG, shot has been used widely for about 100 years, with a growing appreciation for its off-target benefits. Not only is it a common immunotherapy for early-stage bladder cancer, it also seems to train the body’s first line of immune defense to better fight infections. With an immunization specifically targeted against the pandemic-causing Covid-19 disease at least a year away, the World Health Organization says it’ s important to know whether the BCG vaccine can reduce disease in those infected with the coronavirus, and is encouraging international groups to collaborate with a study led by Nigel Curtis, head of infectious diseases research, at the Murdoch Children’s Research Institute in Melbourne. “It can boost the immune system so that it defends better against a whole range of different infections, a whole range of different viruses and bacteria in a lot more generalized way,” said Curtis, who’s also a professor of pediatric infectious diseases at the University of Melbourne and head of the infectious diseases unit at the city’s Royal Children’s Hospital. Hospital staff who volunteered to be part of a six-month trial in Australia involving 4,000 health-care workers will be randomly allocated to be vaccinated starting Monday against seasonal influenza and TB, or the flu shot only. A placebo vaccine won’t work as a control in this case because the BCG shot typically causes a localized skin reaction that leaves a scar, making it obvious which group received the TB vaccination. Similar research is going on in the Netherlands. Curtis, in an interview Saturday, said he’s in discussions with potential trial sites in other Australian cities as well as Boston. Although the inexpensive vaccine, which is used to immunize some 130 million newborns worldwide each year, may potentially offer protection to a broader group of people, the priority is on health workers who are at higher risk from being infected with coronavirus while caring for sick patients. “We need to think of every possible way that we can protect health-care workers,” Curtis said. “And there’s going to be a particular need to reduce the amount of time that our health-care workers are absent.” Studies in infants in Africa have shown that the BCG vaccine offers protection against TB and other pediatric infections, probably by enhancing the body’s innate immune system -- specifically white blood cells that target non-specific pathogens before an antibody response has kicked in usually days later. Blood samples taken at the start and end of the trial will determine who was infected with the coronavirus, while participants will log any symptoms during the trial period. The study’s data monitoring committee will review the results after three months to look for any signs that the approach is working. “We wouldn’t be doing this if we didn’t think that this might work,” Curtis said. “We cannot guarantee that this will work. And of course, the only way to find out is with our trial.” -- 非醫學專業不敢亂翻譯QQ 但大致上是因為開發新疫苗太久 WHO鼓勵世界各國專家找找舊的方法 有人想到某種結核疫苗(卡介?) 能讓免疫系統廣泛的對抗病毒和細菌 因為是百年前研發的疫苗 很安全 現在讓很多前線醫護人員人體試驗中 大概就是彭博社這則新聞過後 小道開始狂拉 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 118.163.69.237 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Stock/M.1585548147.A.D25.html

重點是你還信WHO

不是,看原文只是在說提高身體免疫力而已,不是說他

對冠狀有效果,不然台灣跟日本人都不會得啦。

笑到射X 病急亂投醫

peter080808, 11F
全世界誰沒打過卡介?

Skabo, 12F
全世界媒體都會捕風捉影 不要臉程度有點差別而已

whaskey, 13F
國外很多地方是沒有全面施打的,美國就是。

whaskey, 14F
而且成年人打其實效果不彰,意義不太大,

zithromax, 15F
卡介苗在坐都有打過哈 不過卡介苗是活菌副作用多

zithromax, 16F
國外是不會打的 現在台灣也沒強制要打卡介苗

zithromax, 17F
而且更麻煩的是打卡介苗結核菌測試會陽性 國外醫師

zithromax, 18F
會很緊張

peter080808, 19F
卡介用處只是讓免疫系統脆弱的新生嬰兒認識細菌感

peter080808, 20F
染而已

hisashi, 21F
who反指標?

大家都陽性就不恐慌了 利多?

peter080808, 24F
過了嬰兒期 我們每天接觸上億細菌 卡介苗有屁用喔

peter080808, 25F

gk1329, 26F
也不是不可能 卡介苗剛出生就打 成年後抗體變弱

喔喔喔喔喔 爪爪

可以解釋為何年齡越低 症狀越輕

peter080808, 30F
活到武漢肺炎危險年齡的人 免疫系統該認識的細菌早

peter080808, 31F
就認識光了啦

gk1329, 32F
可以研究看看啊

donkilu, 33F
連卡介苗都搬出來,想解藥想瘋了...

gk1329, 34F
而且有朋友說這只病毒特性跟肺結核很像 都很會藏

eipduolc, 35F
卡介長大還要打耶

eipduolc, 36F
還是現在一劑就好?以前不是到12歲左右還要再打

gk1329, 37F
現在應該取消第二次再打了

bing6715, 38F
這種新聞也敢拉股票 貪

但是要說有效就太早了

下一篇本草綱目

bryanyang507, 87F
乾脆本草綱目全部試一遍好了 還不上萬二

wildwoof, 88F
結果之前提到的藥到底哪一個有效?還是被治癒的都

wildwoof, 89F
還是靠自身免疫力而已

Magicwind, 90F
台灣大多數有打卡介苗,包括一開始中標的台商們

Magicwind, 91F
對卡介苗不太熟悉的歐美人士才會幻想卡介苗有效

Coolspot, 92F
為啥歐美這麼慘亞洲卻還好用卡介苗思考就有答案了

Coolspot, 93F

好了啦 趕快賣一賣 好睡覺

annler1218, 95F
本草綱目有好笑到XDDD

原來是疫苗版,我還以為是股版

MADAOTW, 97F
卡介苗?台灣日本幾乎所有人都有打過
