風險減低四成
Multiple studies have indicated that the pneumonia and influenza vaccines are linked to a 40% lower chance of developing Alzheimer’s.
多項研究指出，接種肺炎與流感疫苗後，罹患阿茲海默症的風險可減低四成。
indicate(v.)指出chance(n.)機率develop(v.)發展、罹患
In 2020, Albert Amran, a medical student at The University of Texas, analyzed the records of 9,066 patients over 65.
2020年，一名德州大學醫學中心學生艾伯特·阿姆蘭針對9,066名65歲以上的患者進行分析。
medical(adj.)醫學的analyze(v.)分析analysis(n.)分析record(n.)紀錄patient(n.)病人
His study showed that vaccination against pneumonia reduced the risk of Alzheimer’s by up to 40% in people between the ages of 65 and 75.
他的研究顯示，在65至75歲的長者中接種過肺炎疫苗者，罹患阿茲海默症的風險降低了四成。
against(prep.)對抗up to=上達至
Inspired by this study, Avram S. Bukhbinder led a team of medical experts to further test this hypothesis.
受這項研究啟發的克賓德於是帶領醫學專家團隊進一步驗證這個假設。
be inspired by=受...啟發inspiration(n.)靈感further(adv.)進一步hypothesis(n.)假說
They compared the rate of Alzheimer’s disease between patients with and without the flu vaccination among records of over 1.87 million patients.
他們比對了187萬名患者中，接種疫苗者與無接種者之間罹患阿茲海默症的比率。
compare(v.)比較rate(n.)比率among(prep.)在...之中
Their newest research from 2022 showed similar results: people who were vaccinated at least once over a four-year period were 40% less likely to develop Alzheimer’s.
他們2022年的最新研究結果很相近：四年內接種至少一劑疫苗者，在這段期間罹患阿茲海默症的機率減低了四成。
latest=最新的who引導出關係子句likely(adj.)有可能的
“The strength of this protective effect increased with the number of years that a person received an annual flu vaccine — in other words, the rate of developing Alzheimer’s was lowest among those who consistently received the flu vaccine every year,” said Bukhbinder.
克賓德表示：「保護力的強度會隨著每年接種流感疫苗而提升，換言之，每年定期接種流感疫苗者，罹患阿茲海默症的比率最低。」
strength(n.)效力protect(v.)保護effect(n.)效果increase(v.)增加、decrease(v.)減少annual(adj.)一年一次的in other words=換句話說(put sth in another way)consistent(adj.)始終如一的
While all researchers observed positive effects, the results gave them a new question: why were the flu and pneumonia vaccines effective against Alzheimer’s?
儘管研究人員觀察到了正面效果，但該結果也引起他們的疑惑：為何流感與肺炎疫苗能有效預防阿茲海默症？
observe(v.)觀察positive(adj.)正面的negative(adj.)負面的
In addition to this, there are several different flu and pneumonia vaccines available, so further research will be required to better understand what is happening.
除此之外，市面上有多種不同的流感與肺炎疫苗，唯有進一步研究才能了解更多。
In addition to=除此之外、再加上(On top of that, Besides)require(v.)要求
The authors of the study are already speculating whether or not COVID-19 vaccines may have the same effect.
這項研究的作者們也在猜測新冠疫苗是否也有同樣的效力。
speculate(v.)推測whether(conj.)是否
