The COVID-19 mRNA vaccines from Moderna and Pfizer–BioNTech had short-term efficacy rates of over 90 percent against the original SARS-CoV-2 virus. Prior to mRNA, drug trials on pathogens other than COVID-19 were not effective and had to be abandoned in the early phases of trials. The reason for the efficacy of the new mRNA vaccines is not clear.
When the SARS-CoV-2 virus emerged in China in 2019, BioNTech had already used mRNA technology to design a vaccine against the Zika virus, which had infected hundreds of thousands of pregnant women ...
Hoerr did experimental research on the stabilization of messenger ribonucleic acid (mRNA). In 1999, he received his PhD from Günther Jung, Institute of Organic Chemistry, in cooperation with Hans-Georg Rammensee, Institute of Immunology and Cell Biology (both: University of Tübingen) on the topic of RNA vaccines for the induction of specific cytotoxic T lymphocytes (CTL) and antibodies.
The first mRNA-based vaccines received restricted authorization and were rolled out across the world during the COVID-19 pandemic by Pfizer–BioNTech COVID-19 vaccine and Moderna, for example. [55] The 2023 Nobel Prize in Physiology or Medicine was awarded to Katalin Karikó and Drew Weissman for the development of effective mRNA vaccines ...
How COVID‑19 vaccines work. The video shows the process of vaccination, from injection with RNA or viral vector vaccines, to uptake and translation, and on to immune system stimulation and effect. Part of a series on the COVID-19 pandemic Scientifically accurate atomic model of the external structure of SARS-CoV-2. Each "ball" is an atom. COVID-19 (disease) SARS-CoV-2 (virus) Cases Deaths ...
Strands of mRNA, or messenger RNA, are tiny snippets of genetic code that tell the body how to build proteins, essential building blocks of every cell in the body. The idea behind an mRNA vaccine ...
