英國牛津大學的科學家們已經研發出一種有望 “改變世界” 的瘧疾疫苗。該團隊表示,初期試驗結果顯示此疫苗對瘧疾有80%的保護,他們希望能在明年推出此疫苗。

It looks increasingly likely that Oxford University’s malaria jab is the real deal. A highly effective vaccine with the potential to save millions of lives in the coming years.

牛津大學研發的瘧疾疫苗看上去似乎有可能成為一個對抗瘧疾真正有效的疫苗。這是一種高效疫苗,有望在未來幾年挽救數百萬人的生命。

Trials in West Africa involving 450 children had already shown that three doses of the vaccine gave around 75 per cent protection for a year. New results show that a booster dose at 12 months extends protection for a second year, at up to 80 per cent.

在西非進行的、由450名兒童參與的試驗已表明,接種完三劑疫苗後一年內的保護效力約為75%。新試驗結果顯示,完成全程接種12個月後注射加強針,可將保護期延長一年,疫苗的保護效力達80%。

We may not need to wait long for definitive results from larger trials. Scientists plan to submit data to the World Health Organisation within weeks, with a view to getting the vaccine approved.

我們可能不需要等待太久,就可以從更大規模的試驗中獲得最終資料結果。科學家計畫在未來幾週內向世界衛生組織提交資料,這是為了讓疫苗獲得批准。

The Oxford team has partnered with the Serum Institute in India – the world’s biggest vaccine manufacturer – and says at least 100 million doses could be produced next year at low cost to make it accessible to many of the world’s least developed countries.

牛津團隊與世界上最大的疫苗製造商印度血清研究所合作,並表示明年至少可低成本生產1億劑疫苗,讓世界許多最不發達的國家都有機會用此疫苗對抗瘧疾。
