> There are clear signals that this vaccine is more dangerous than any other vaccine brought to market thus far. You need to be more specific than "this vaccine". [0] lists 21 vaccines that are "approved", and an additional 89 vaccines in development. From context, I assume you are talking about an mRNA vaccine approved for use in the USA, which brings the number of possible vaccines down to 2. Regardless, what signs are you looking at for "this vaccine" being the most dangerous one to hit the market. Of the top of my head, the vaccine I would be most worried about getting is the one for small pox. This vaccine infects you with a live, not weakened form of the vaccinia virus. After getting the vaccine you are given specific instructions on how to care for the injection sight. Failure to properly care for the injection side can lead to the virus spreading to other parts of the patients body, or even other individuals. Even when properly cared for, the smallpox vaccine often leave a permanent scar on the injection site. The second vaccine that comes to mind is the polio vaccine, which can cause outbreaks of vaccine derived polio in the surrounding population (although patient 0 typically does not experience adverse effects in this case). Currently vaccine derived polio is far more common than natural polio. For polio, we have switch over to a less effective vaccine to help avoid vaccine derived polio.
