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.
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.
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.
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.
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.
