When the flu season begins during the late fall of each year, you may hear doctors or health officials remind the public to get their annual flu shots. However, many people have asked, “If the vaccine is effective, then why do people need a new one each year?”
According to medical experts, people need a yearly flu shot because the virus that causes the flu is constantly evolving. The virus, known as influenza, can cause a wide range of uncomfortable symptoms, from a mild sore throat to severe muscle pains. For some demographics, such as the elderly or the overweight, getting sick with the flu can be deadly.
Since the outer structure of the influenza virus changes all the time, epidemiologists must work hard to develop new vaccines based on new strains of the virus in order for them to be effective. At influenza surveillance centers around the world, new strains of the virus are reported and analyzed each year. Around February, the World Health Organization (WHO) decides which of these strains are most likely to be prominent in the coming year. Scientists then get to work to produce a new vaccine before the next flu season arrives.
It’s also important to remember that the body’s immune system is constantly developing as well; it’s not just the influenza virus that is changing. That means a vaccine that might have been effective last year is likely to be useless after 12 months. That’s why experts recommend getting a new flu shot yearly to protect yourself and others. Remember: the vaccines not only alleviate the worst symptoms of the virus but also help reduce transmission of the viral disease throughout the population.
1. According to the passage, when are people most likely asked to get flu shots?
(A) Around February. (B) During the summer season. (C) Near the end of autumn. (D) In the middle of winter.
2. What is the main reason doctors recommend the public get flu shots every year?
(A) The quality of vaccines improves every year.
(B) The vaccines alter the outer structure of the flu virus.
(C) The body’s immune system reduces the effectiveness.
(D) The strains of the flu virus circulating each year are different.
3. Which of the following statements is true?
(A) People with obesity should avoid getting flu shots.
(B) Old vaccines don’t work as effectively as new ones.
(C) Scientists work on new flu vaccines before February.
(D) The WHO is in charge of reporting and analyzing virus strains.

每年秋末流感季節開始時，你可能會聽到醫師或衛生局人員提 醒民眾接種年度流感疫苗。然而，很多人都問過:「如果疫苗有效 的話，那為什麼人們每年都需要接種新的疫苗呢?」
根據醫學專家的說法，人們之所以需要每年注射一次流感疫 苗，是因為導致流感的病毒不斷地在演變。這種被稱為流感的病毒 會引起各種不適的症狀，從輕微的喉嚨痛到嚴重的肌肉酸痛。對某 些族群來說，像是年長者或過重者，感染流感可能會致命。
由於流感病毒的外部結構一直在變，流行病學家必須根據新 病毒株來努力開發新疫苗，以使其有效。在世界各地的流感監測中 心，每年都會報告及分析新的病毒株。在二月左右，世界衛生組織 (WHO)選出哪些病毒株最有可能會在來年流行。接著，科學家 便會趕在下個流感季節到來前，開始製造新疫苗。
同樣重要的是，要記得人體的免疫系統也是不斷地在演變;不 是只有流感病毒在改變。那意味著去年可能有效的疫苗有可能在過 了十二個月後就沒用了。那就是為何專家建議每年接種新的流感疫 苗以保護自己和他人。請記住:疫苗不僅可以減緩病毒最嚴重的症 狀，還有助於減少病毒性疾病在人群間傳播。
1. 根據本文，人們什麼時候最有可能被要求接種流感疫苗?
(A) 二月左右。
(B) 夏季期間。
(C) 接近秋末。
(D) 深冬時分。
2. 醫生建議大眾每年接種流感疫苗的主因是什麼?
(A) 疫苗的品質逐年提升。
(B) 疫苗會改變流感病毒的外部結構。
(C) 身體免疫系統降低疫苗效力。
(D) 每年流行的流感病毒株不同。
3. 下列敘述何者是正確的?
(A) 肥胖者應避免接種流感疫苗。
