The undeniable fact is that vaccine test protocols are meant to take a long time to allow time to determine any long term harm or complications. Assuming they started trials in October, that is barely enough time, if at all, to determine if they are even effective. Not nearly enough time to figure out if they are safe. Anyone who says different is lying.
If this pandemic follows the same course as others, we should expect it to die out on its own within the next year. Everything about this situation screams rush job to try to profit off of mass hysteria. But you go ahead and get your vaccine, because everyone knows all the experts agree that the benefits outweigh the risks on every vaccine for everybody. Anyone who says different is a brain dead, conspiracy theorist, anti-vaxxer.
