Influenza vaccines are strain specific, and their efficacy varies greatly year to year based on how well the vaccine virus matches the circulating strains. Additionally, older adults have reduced vaccination responses. The COVID-19 pandemic highlighted the increased mortality rate in older adults for ...
12. An alphavirus replicon particle chimera derived from venezuelan equine encephalitis and sindbis viruses is a potent gene-based vaccine delivery vector; 13. Self-Amplifying mRNA Vaccines Expressing Multiple Conserved Influenza Antigens Confer Protection against Homologous and Heterosubtypic Viral Challenge...
大约八年后,他们在人体中评估了第一款mRNA疫苗,当时从黑色素瘤(melanoma)患者的肿瘤中提取了遗传物质,并用于合成mRNA,该mRNA作为一种自体疫苗(autologous vaccine)细胞集落刺激因子(granulocyte-macrophage colony-stimulating factor,GM-CSF)一同给药作为佐剂。这种方法被证明是安全的,并在一些患者中增加了抗肿瘤免疫反应...
2024 年 3 月 5 号,国内学者在Biorxiv上发表文章:A 10-valent composite mRNA vaccine against both influenza and COVID-19,他们创造性地设计合成了一种新型 10 价 mRNA 新冠流感复合疫苗,称为 FLUCOV-10,该疫苗编码来自4种季节性流感病毒和2...
mRNA vaccines represent a promising alternative to conventional vaccine approaches because of their high potency, capacity for rapid development and potential for low-cost manufacture and safe administration. However, their application has until recently been restricted by the instability and inefficient in...
have developed an mRNA lipid nanoparticle (LNP) vaccine that contains antigens from all 20 known subtypes of influenza A and B viruses. The vaccine elicited high levels of antibodies in mice and ferrets, and protected animals against disease symptoms and death after infection.关键词:...
用mRNA技术对抗癌症则是通过一种叫做“癌症疫苗”(cancer vaccine)的法疗来实现的。癌症疫苗的总体思路是让一个人的免疫系统可以精准区分肿瘤细胞和正常细胞,通过将肿瘤抗原以多种形式(如核酸、蛋白多肽等)导入患者体内,来刺激患者体内自身免疫系统的反应从而...
