A source knowledgeable of the study told Reuters on Friday that the data indicates that the vaccine will not need to be modified in order to protect against the variant, also known as P one, which is believed to have originated in the Amazonian city of Manaus.

該研究的一位知情人士週五告訴路透社，數據表明，疫苗將不需要修改，以防止變種，也稱為P一，據信起源於亞馬遜城市馬瑙斯。

Last month, South Africa paused the use of the AstraZeneca vaccine in the country after early results indicated that it was less effective against the South African variant, which is similar to P one.

上個月，南非暫停了阿斯利康疫苗在該國的使用，因為早期的結果表明，它對南非變種的效果較差，這與P一類似。

The source did not provide the exact efficacy of the vaccine against the Brazilian variant, but set the full results of the study should be released soon, possibly in March.

消息來源沒有提供針對巴西變種的疫苗的確切療效，但設置的研究的完整結果應該很快，可能在三月發佈。

The promising information comes as a small sample study suggested that the Covid 19 vaccine developed by China's Sinovac may not work effectively against the Brazilian variant.

這一有希望的資訊是在一項小樣本研究表明，中國華衛公司開發的Covid 19疫苗可能無法有效對抗巴西變種。

Brazil is currently confronting a brutal and long lasting second wave of the coronavirus, hitting a daily record of more than 1900 deaths on Wednesday.

巴西目前正面臨著殘酷而持久的第二波冠狀病毒，週三創下了每天1900多人死亡的記錄。

The P one variant is among the factors that epidemiologists believe is contributing to a rise in cases and deaths there with concern in the scientific community about the variance resistance to vaccines.

P一變種是流行病學家認為是導致病例和死亡人數上升的因素之一，那裡有科學界對疫苗的變異抗性的關注。
