美国疫苗临床试验正式启动,最快7月能够得到结果

据美联社报道,美国一位匿名政府官员表示,16日起,将对预防新冠肺炎的一种疫苗展开临床试验。临床试验由美国国家卫生研究院资助,将在位于西雅图的一家卫生研究所进行。目前,试验尚未公开宣布。首位参与临床试验的人将于16日接种实验疫苗。美国公共卫生官员称,要完全验证疫苗是否有效,将花费12至18个月的时间。

The novel coronavirus pneumonia vaccine will be launched in 16 days, and a clinical trial will be launched on the new crown pneumonia, a US government official said on. The clinical trial, funded by the National Institutes of health, will be conducted at a health research institute in Seattle. At present, the test has not been publicly announced. The first person to participate in the clinical trial will be vaccinated on the 16th. U.S. public health officials say it will take 12 to 18 months to fully verify the effectiveness of the vaccine.

据了解,该疫苗由生物技术公司Moderna开发,美国国立卫生研究院(NIH)资助,疫苗名称为mRNA-1273,是一种核酸疫苗。

It is understood that the vaccine was developed by the biotechnology company Moderna and funded by the National Institutes of Health (NIH). The name of the vaccine is mrna-1273, which is a nucleic acid vaccine.

核酸疫苗(nucleic acid vaccine),也称基因疫苗(genetic vaccine),是指将含有编码的蛋白基因序列的质粒载体,经肌肉注射或微弹轰击等方法导入宿主体内,通过宿主细胞表达抗原蛋白,诱导宿主细胞产生对该抗原蛋白的免疫应答,以达到预防和治疗疾病的目的。

Nucleic acid vaccine, also known as genetic vaccine, refers to the plasmid vector containing the encoded protein gene sequence, which is introduced into the host body by means of intramuscular injection or micro bomb bombardment, through which the host cell expresses the antigen protein and induces the immune response of the host cell to the antigen protein, so as to achieve the purpose of disease prevention and treatment.

目前NIH将招募45名志愿者在西雅图一处研究机构内进行临床试验,不过试验目标是测试疫苗的安全性(是否有副作用),现阶段并不会让实验者感染病毒。

Currently, NIH will recruit 45 volunteers to conduct clinical trials at a research institute in Seattle, but the goal of the trial is to test the safety of the vaccine (whether there are side effects). At this stage, the experimenter will not be infected with the virus.

目前全世界有数十个研究小组同时开发疫苗,这些小组使用不同的技术开发不同类型的疫苗,有一些研究人员甚至在研发临时疫苗,可以在1-2个月内保护健康。

At present, there are dozens of research groups around the world developing vaccines at the same time. These groups use different technologies to develop different types of vaccines. Some researchers are even developing temporary vaccines, which can protect health within 1-2 months.

不过需要注意的是,即便再快的研究速度,也需要在1-1.5年时间才能成功研发疫苗,所以大家还要继续耐心等待。

However, it should be noted that even if the research speed is fast, it will take 1-1.5 years to successfully develop the vaccine, so we need to continue to wait patiently.
