But an mRNA vaccine is different, because rather than having the viral protein injected, a person receives genetic material – mRNA – that encodes the viral protein. When these genetic instructions are injected into the upper arm, the mu...
"After almost a whole year of COVID-19 ravaging the world, its impact has already been enormous," says Borgos. "Pfizer and BioNTech are reporting 90% efficacy using their mRNA-based vaccine. This result is much better than most people dared hope, and it helps to boost our faith in the...

Pancorbo: I am not sure anyone knows this accurately at this point, since no mRNA vaccine has been manufactured before at any scale close to what will be required for COVID-19. I am going to dare say that it will take at least a couple of weeks per batch. TA: What about adenovirus ...
mRNA vaccine is based on the principle that mRNA is an intermediate messenger to be translated to an antigen after the delivery into host cells via various routes. RNA molecules have been utilized as therapeutic and research tools for more than two decades, with the usage ranging from in vitro...
Amyris, for example, has had success with its sugarcane substitute for squalene (an important vaccine adjuvant) because squalene is a natural ingredient harvested from shark livers. Amyris offers high quality, sustainability, a steady supply, and a stable price, the latter being an important part ...
An mRNA vaccine is injected into the body where it enters cells and tells them to create antigens. These antigens are recognised by the immune system and prepare it to fight coronavirus. No actual virus is needed to create an mRNA vaccine. This means the rate at which the vaccine can be...
Translation: The mRNA is carried back out of the nucleus by the cell's enzymes. The virus then uses the cell's natural protein-making mechanisms to make long chains of viral proteins and enzymes. Assembly: RNA and viral enzymes gather at the edge of the cell. An enzyme called protease cu...
Why did I just say “faux vaccines”? Because a real vaccine accomplishes the following: It introduces a small, controlled amount of the known virus into the system allowing the body to produce a first line of defense ‘Antibodies’ that serve to protect the body. This process is called ac...
It is also great that some vaccine companies entered into second-source deals, which allowed huge volumes of their vaccines to be manufactured by other firms. This was a crucial and remarkable step. (It’s as if Ford let Honda use its factories to build Accords.) Just one example: In les...
