In the case of the COVID-19 vaccines, instead of injecting a weakened or dead virus into the body, the mRNA causes the body to make a piece of the virus in order to create an immune response. The manufacturing time is only a fraction of that involved in developing a traditional vaccine...
Why does China want to develop its own mRNA vaccine? mRNA was discovered in the early 1960s and research into how it could be delivered into cells began in the 1970s. It wasn't until 1990 that mRNA flu vaccines were tested in animals, and only during the past decade...
The mRNA vaccine technology and its success against COVID-19 have opened doors to explore its uses against a variety of diseases. This is because the makeup and delivery mechanism now provides scientists a basic template to target any virus. They can simply insert the code for a particular vi...
Dozens of clinical trials are testing new mRNA vaccines, using machine learning to identify antigens, and embracing new technologies such as self-amplifying RNA.#Dozens of clinical trials are testing new mRNA vaccines, using machine learning to identify antigens, and embracing new technologies such ...
"This is the first time mRNA has been explored for use in Alzheimer's disease," Dr. Nisbet said. "Our work in cell models demonstrates that this technology can serve purposes other than vaccine development." She likened mRNA to aninstruction manualfor cells. ...
Autologous vaccinesare a form of personalized medicine in which cells from a person's own body (such as cancer cells or immune cells) are harvested to make a vaccine for that person. Allogeneic vaccinesare created from cells that are harvested from others and/or engineered in the lab. This ...
It can take years to make a new vaccine, so this was a breakthrough. "How is that possible?" Aubrey asked. "Well, it has to do with our technology," said Hoge. "We use something called messenger RNA, or mRNA for short. It's really just an instruction molecule, kind of like a ...
to create widespread immunity with minimal loss of life. 来激活人体的免疫系统, 挽救更多的生命。 So how quickly can we develop vaccines when we need them most? 那么在紧急状态下, 最快需要多久可以研发出疫苗呢? Vaccine development can generally be split into three phases. ...
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...
