It's entirely possible that the vaccine is innocuous for right now. It's possible that in the future when there is another pandemic or something else, they can get people to inject another chemical in their body that reacts with the chemicals from this vaccine.

I understand, this is conspiracy theory kind of stuff... but much like science, we gotta question everything. I cannot prove the above, nor disprove it. And for that, I am incredibly skeptical of the vaccine.
