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.
【C20】
选项
A、result
B、system
C、process
D、foundation
答案
D
解析
空格所在部分为it could lay the________for a universal coronavirus vaccine (它可以为一种通用的冠状病毒疫苗奠定________),其前提是If it works and is safe(如果疫苗在人体试验中有效且安全)。由此可知,疫苗人体试验是否有效决定了后续工作如何进行,故选择选项D foundation,lay the foundation for…为固定搭配,意思为“奠定……的基础”。A项“结果”、B项“系统”、C项“过程”都无法与lay构成合理的搭配,故排除。
