An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. [1] The vaccine delivers molecules of antigen -encoding mRNA into cells , which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus ) or by a ...

2021年8月30日 · mRNA vaccines inject cells with instructions to generate a protein that is normally found on the surface of SARS-CoV-2, the virus that causes COVID-19. The protein that the person makes in response to the vaccine can cause an immune response without a person ever having been exposed to the virus that causes COVID-19.

2024年10月25日 · Current mRNA vaccines are available for COVID-19. A provider vaccinates you with a shot in your arm (or leg, for young kids). What is an mRNA vaccine? An mRNA vaccine is a preventive treatment that helps your body learn to fight diseases. A healthcare provider gives you the vaccine in a shot or series of shots.

mRNA vaccines use a piece of mRNA that corresponds to a protein on a virus. Vaccines for COVID-19 are the only mRNA vaccines authorized or approved by the FDA.

2025年3月18日 · RNA vaccines are composed of the nucleic acid RNA, which encode antigen genes of an infectious agent. When administered to host cells, the RNA is translated into protein antigens that...

2024年11月7日 · MRNA vaccines introduce your immune system to an antigen in a unique way. Instead of using a weakened or inactivated form of a pathogen, they work by teaching your body’s cells how to temporarily...

Messenger RNA (mRNA) vaccines have emerged as a transformative platform in modern vaccinology. mRNA vaccine is a powerful alternative to traditional vaccines due to their high potency, safety, and efficacy, coupled with the ability for rapid clinical development, scalability and cost-effectiveness in manufacturing.

2025年3月14日 · Development and deployment of messenger RNA (mRNA) vaccines for SARS-CoV-2 was a tremendous public health achievement in the face of a global health crisis. That success generated immense excitement around mRNA technology, significantly accelerating its development and application to a wide range of diseases.

The potential of mRNA vaccine as a technology to rapidly respond to public health emergencies of infectious diseases, in addition to application for prophylactic vaccines for additional infectious diseases, have underscored the need for international regulatory convergence for RNA vaccines.

2021年8月25日 · In this Review, we describe the technologies that underlie mRNA vaccines, with an emphasis on lipid nanoparticles and other non-viral delivery vehicles. We also overview the pipeline of mRNA...
