In the past 20 years alone, three coronaviruses have caused major disease outbreaks. First came the original SARS virus in 2002.【C1】________. in 2012, MERS was identified. In 2019, SARS-CoV-2【C2】________.
Hundreds of other coronaviruses are known to be【C3】________in bats and other animals. Scientists have warned that some of them could arise in the future and【C4】________infect people. Our current COVID-19 vaccines were specifically【C5】________for SARS-CoV-2, but what if a next-generation vaccine could protect【C6】________both known and unknown coronaviruses?
Scientists at the Walter Reed Army Institute of Research are working on a so-called universal coronavirus vaccine. Dr. Kayvon Modjarrad is【C7】________the effort. They have developed a vaccine specifically for SARS-CoV-2, and found that the immune response that it【C8】________is active against all the variants, as well as other coronaviruses like SARS-CoV-1. And this gives them confidence that it can be a platform for the entire coronavirus family.
The vaccine is known as SpFN, which combines nanoparticles from ferritins with coronavirus spike proteins. But making the vaccine wasn’t as【C9】________as attaching one protein to another. Modjarrad and his colleagues had to【C10】________which parts of the spike to attach to which type of ferritin and how to【C11】________the two proteins together. It took months of trying more than 200 different【C12】________. By June of last year, the team found one version that succeeded where others had failed. They then【C13】________the experimental vaccine in mice and monkeys.
The team also turned to less【C14】________animals for testing. Working with scientists in India, they【C15】________horses with the vaccine to learn how strong the【C16】________response was. And they【C17】________with Helen Dooley at the University of Maryland to vaccinate sharks—which make special antibodies.
The results are【C18】________. but animals aren’t people. The Army vaccine is now being tested in a small, early-stage trial in humans.【C19】________it works and is safe, it could lay the【C20】________for a universal coronavirus vaccine.
【C18】
选项
A、average
B、economic
C、encouraging
D、disappointing
答案
C
解析
空格所在部分为The results are________. but animals aren’t people,根据上文可知,疫苗已经在动物身上进行了试验,并且鲨鱼体内可以产生特殊的抗体,同时根据but可知逗号前后为转折关系,but,后指出动物并不是人,暗示了疫苗在动物身上试验成功并不代表就适用于人体。所以可以判断but之前的部分表达肯定含义,but之后的部分才会话锋一转,介绍疫苗的有待提升之处,选项中满足条件的为encouraging“令人鼓舞的”,故答案为选项C。A项“平均的;一般的”,B项“经济的”,D项“令人失望的”,代入后均不符合文意。故排除。
