They are not really all that new. The research for mRNA vaccines began over 50 years ago.
mRNA vaccines are among the safest vaccines ever made. There is nothing in an mRNA vaccine that can make you sick. What they are is instructions for your immune system on how to recognize certain viruses when it sees them. You can literally email the mRNA sequence to a different lab and, provided they have the right equipment, they can make the vaccine without ever needing a sample of the virus.
The mild symptoms some people get is the immune system activating and building the viral antigens specified by the mRNA vaccine, but there is no danger of getting Covid-19 or any other disease from the Covid-19 vaccine.
One side note: while I know you are using the medical definition of “mild symptoms”, please be aware that this doesn’t match the colloquial definition. You can be absolutely miserable for several days (and a number of people are) and still be considered mild. Unless you get into symptoms like difficulty breathing or hospitalization, it still counts as mild.
The immune response can be bad for some people. There are risks and side effects. They just happen to be massively outweighed by the benefits.
The vaccine does not cause illness but an inappropriate immune response can. The symptoms can be bad but generally are milder than the equivalent response to covid. Those at higher risk to vaccine side effects seems to be a similar cohort to those at risk of more severe reaction to covid.
Something I found interesting is why it took 50 years (which is a detail anti-vaxxers never seem to know) for a usable result to reach the open market. There have been a ton of studies and trials trying to get a useful vaccine, but very little of it (historically) was successful. This wasn’t because of any health risks, but rather because they weren’t effective enough. The mRNA simply broke down too fast for your immune system to react.
If you are concerned about safety, you should be applauding mRNA over the older methods.

Fully agree with everything you wrote.
