A vaccine isn't a "medicine". You only are exposed to about 25-100ug of payload which is an incredibly small dose, once or twice. That doesn't compare to taking 100s of mg of something once or twice a day for weeks/months/years. Neither does it compare with eating whatever you buy off of grocery shelves that might be synthetic, which is going to be higher doses and more chronic.

The mRNA sticks around for a day or three and then its all effectively gone and the 'infected' cells are disassembled by the immune system. The only thing that remains is the immune reaction, and the side effects (other than the rare immediate anaphylaxis) will be autoimmune reactions triggered by exposure to the antigen.

And we have 250 years of experience with vaccines and we've studied autoimmune conditions for many years, and there's a whole field of medicine devoted to it. And based on all that experience we know what kinds of side effects there could be and that they all show up within 3 months of exposure to the antigen. That is why vaccines don't need more than 3-6 months of a trial in order to determine safety (they often need much longer to determine efficacy).

If you get sick 6+ months after getting vaccinated then it wasn't the vaccine.

I also would take the mRNA vaccine over the Sinopharm, there's far more antigens in Sinopharm or viral vector vaccines that your body has never been exposed to. There's much less different types of antigens in the mRNA vaccines to trigger autoimmune effects. You're likely thinking about the risks backwards. The worrisome thing isn't the american pharmaceutical industry, the bigger issue is the entirely alien (to your body) proteins in the pandemic virus.
