This is the journal abstract - link below. 'Circulation' has an impact factor of bout 3, so is pretty reasonable. I'm guessing these are the sorts of findings the FDA wants to hide with their recent proposal to keep the vaccine research data hidden from public view.
Medicine comes down to risk versus reward, and just because there's risk doesn't mean the risk necessary outweighs the reward. It's an individual thing, which is why imo, it should a be a personal choice.
