This article https://science.news/2020-05-25-mrna-vaccines-how-they-work-coronavirus.html published in May 2020 lists the five main risks associated with mRNA vaccines as
1 Sudden onset of autoimmune disorders
2 Heightened inflammation in the body
3 A heightened risk of blood clotting
4 Immune response interference
5 Inability to stop runaway out of control self replication
These risks in addition to many other unknowns are discussed in the article.
Advantages of mRNA vaccines
The main advantage or difference really is that mRNA “drugs” are a synthetic genetic gene therapy and not a vaccine!
– They don’t need to be grown in animal organs or chicken eggs, eliminating the risk of cross-species contamination of the vaccine.
– mRNA vaccine makers currently claim that their vaccines don’t require the use of inflammation-inducing adjuvants, which are widely known to be responsible for many of the toxic effects of present-day vaccines.
– Because the vaccine doesn’t consist of pathogens, there is zero risk of “live” pathogens accidentally being injected into the patient, contributing to further spread of infectious disease. This has occurred numerous times with classic vaccines.
– mRNA vaccines are much easier and faster to produce than traditional vaccines. Their manufacture is also easily standardized, with far greater purity and quality control potential than with vaccines which are made from animal tissue.
– The injection doses can be orders of magnitude smaller than for traditional vaccines.
– When mRNA vaccines are specifically programmed to target a patient’s pathogenic cancer tissue, the customized mRNA “vaccine” can be incredibly effective at teaching the body to destroy cancer cells. This is sometimes referred to as a “cancer vaccine,” although the label is misleading. It’s actually a form of personalized medicine where the body is aided in the selective destruction of the very specific cancer cells which are replicating in that patient’s body.
