Although it's antiquated and difficult to extrapolate data, VAERS (
https://vaers.hhs.gov/) is the official database for reporting adverse effects. The website openvaers.com does a good job sorting the raw data into a digestible state. Per the reports, there have been nearly 11,000 covid vaccine related deaths, 30,781 covid vaccine related hospitalizations, and 463,436 covid vaccine related adverse event reports. It is assumed that these reports only represent a small percentage of the true numbers.
No medical professional I know is simply telling every patient not to get vaccinated, but it's a much more complex conversation than the "shut up and get the shot" narrative from so many on this board. For instance, if you have recovered from covid and have natural immunity which data is showing likely leads to broad, long term immunity, it almost never makes sense to get the vaccine. Sure, the odds are that you end up being fine like you seemingly did, but there's really not much evidence that shows it improves your immunity, but there is evidence that those who have recovered from the virus have a higher risk of adverse events as a result of the vaccine. Another example are young women of child bearing age. There are lots of reports of women having severe reactions after the vaccine in regards to their menstrual cycle and there's no long term data on the effects of the vaccine on fertility. Many doctors are cautioning their young women patients that still want to have kids to hold off on the vaccine. Personally, I know two couples that had miscarriages scary soon after the pregnant wife received her second vaccine shot.
And yes. If you are going to cite your MD brother as some source of infallible truth, I think it's important to justify why. Med school spends relatively VERY little time addressing vaccines, and practically no practicing MD spent any time in med school learning about mRNA vaccines. Very few MDs practice medicine that has anything to do with a deep understanding of vaccines. In it's current state, most educated decisions regarding this current vaccine can only be made by the extrapolation and interpretation of data, which many doctors are not taking the time to do (many are). This current "Shut up and get the shot. It's perfectly safe" narrative is intellectually lazy and quite honestly is the antithesis of science.
