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.
【C13】
选项
A、adjusted
B、tested
C、adopted
D、stimulated
答案
B
解析
空格所在部分为They then________the experimental vaccine in mice and monkeys (然后,他们在老鼠和猴子身上________实验疫苗)。该句前一句提到,研究团队发现其中一个版本的疫苗研制成功了,根据此处的then可知应该是时间顺承关系,研制成功后自然需要测试疫苗的效果,所以本题应选择tested。空格后的老鼠和猴子也都能说明是对还处于试验阶段的疫苗进行动物实验,从下一句The team also turned to…animals for testing中也可推出该空应填入tested。故答案为选项B。A项“适应;调整”,C项“采用;领养”,D项“刺激”,代入空格后均不符合句意,故排除。
