導語：目前中國新冠疫苗的研發工作已經取得了很大進展。由陳薇院士領銜的軍事科學院軍事醫學研究院科研團隊研製的重組新冠疫苗一期臨床試驗正在進行（戳這裡回顧）。但我們的科研人員們沒有停下腳步，仍然在為完善疫苗護盾繼續努力。21世紀英文報重磅出品：疫情科普視頻系列《TEENS戰「疫」語言點》——關於疫苗，這些你知道嗎？美國主持人 Laura 小姐姐帶你一探究竟！趕緊點開視頻，跟上 TEENS，在家學習的同時，也要照顧好自己喔！
大家好！歡迎來到新一期的《TEENS戰「疫」語言點》欄目。在今天的節目中，我們會了解疫苗的知識，以及它們如何幫助我們反擊新型冠狀病毒這樣的疾病。
Hello, everyone! We're back with another episode of TEENS』 ANTI-VIRUS LANGUAGE TIPS. In this video, we will learn about vaccines and how they help us to fight back against diseases like the novel coronavirus.
自從中國科學家發現了新型冠狀病毒的基因結構以來，全世界的科學家都在努力開發疫苗。
Since scientists in China found the genetic structure of the novel coronavirus, scientists from all over the world have been working hard to develop a vaccine.
疫苗是一種致病病毒或者病菌的較弱形態。它們能夠幫助人體學會如何應對病毒或者細菌。這讓人能夠在接種之後不易受該病侵襲。
A vaccine is something that has a weaker form of a virus or bacteria that causes a disease. Vaccines help by letting the body learn how to fight the virus or bacteria. This makes it less likely for a person to become sick with the disease later on.
人類第一個成功開發的疫苗是1796年研發出來的天花疫苗。當時，天花是一種極度致命的疾病，在全世界都有爆發。據估算僅僅在20世紀，該病就奪走了3億人的生命。有了疫苗的幫助，天花在1979年被徹底根除。人們相信天花疫苗挽救了2億人的生命。
The first successful vaccine that was ever developed was the smallpox vaccine in 1796. Back then, smallpox was a very deadly disease that had outbreaks all over the world. During just the 20th century, it was estimated to have killed 300 million people. With the help of the vaccine, the disease was completely wiped out by 1979. It is believed that the vaccine was able to save up to 200 million lives.
疫苗的動詞形式是vaccinate，該詞的意思是接種疫苗。當你接種疫苗時，疫苗會進入你的體內。你可以說，我昨天打了疫苗。或者說，我準備去接種疫苗。
The verb form of 「vaccine」 is 「vaccinate」. 「Vaccinate」 means 「to give a vaccine」. When you 「get vaccinated」, it means the vaccine goes into your body. You can say things like: 「I got vaccinated yesterday,」 or 「I am going to get vaccinated.」
疫苗幫助人們應對特定的病毒或者細菌。但是有時候，當病毒或者細菌感染新的患者時，會發生變異。這就是為什麼人們每年都會被推薦打流感疫苗。引發流感的病毒可能發生迅速的變化，而人們需要新的疫苗來防護它。
Vaccines help to fight against a specific virus or bacteria. But sometimes, the virus or bacteria can mutate when it infects someone new. This is why it is often encouraged to get a flu shot each year. The virus that causes the flu can change very quickly and a new vaccine is needed to prevent it.
在新型冠狀病毒疫情爆發之際，我們希望全世界的科研人員能夠團結起來儘快開發疫苗。他們是能夠終結這種新型疾病的英雄。
With the outbreak of the novel coronavirus, we hope that scientists and researchers around the world can work together to make a vaccine soon. They are the heroes who can help to put an end to the new disease.
