CNN原文：

China has become the first country to green-light an inhaled Covid-19 vaccine, paving the way for potential use of the needle-free product in the country, where suppressing the spread of Covid-19 remains a top priority. The vaccine maker, CanSino Biologics, said in a statement Sunday that China’s medicines regulator had approved the inhaled dose for emergency use as a booster vaccine.

中国已成为首个通过吸入式新冠肺炎疫苗的国家，为这种无需注射的产品在中国的潜在使用铺平了道路。目前在中国，控制疫情传播仍然是一项首要任务。该疫苗生产商康希诺生物公司周日在一份声明中说，中国药品监管机构已批准吸入式疫苗的剂量，作为紧急使用的加强疫苗。

6.vaccination rate 疫苗接种率

例句：A low vaccination rate among the elderly is one medical reason used by the authorities to justify the ongoing disease control measures.

政府目前采取的疾病防控措施的其中一个医疗原因，是老年人的疫苗接种率低。

7.clinical trial 临床试验

例句：Clinical trials are underway to test more than a dozen spray vaccines to see if they can create so-called mucosal immunity.

临床试验正在测试十几种喷雾型疫苗，看看它们是否能产生所谓的黏膜免疫。

8.antibody level 抗体水平

例句：In a small study published in August, CanSino researchers reported that a booster of the inhaled vaccine could increase antibody levels.

在8月发表的一项小型研究中，康希诺公司的研究人员报告称，吸入式疫苗的加强剂能提高抗体水平。

9.non-shot vaccine 非注射型疫苗

例句：There’s hope that these non-shot vaccines, which are given as drops, sprays or tablets to the mouth and nose, may also prevent the infection from spreading from person to person -- something injected vaccines don’t do very well following the emergence of new variants of the virus.

这些以滴剂、喷雾剂或药片的形式进入到口鼻腔里的非注射型疫苗，有希望能够防止人传人病毒感染——因为在一般情况下，当出现病毒新变种后，注射型疫苗不能很好地抑制其传播。
