Is it really a "benefit" to sacrifice a few to save the herd? I guess maybe it is from a purely physical survival perspective....but even then I would suspect most of the "disadvantaged" crowd would disagree. Is it ethical to expect people to take such a gamble without having been fully informed of the known risks? I think not. If anyone wishes to risk themselves for good of the many fully understanding the risks, I will call them a hero. But when some take the fall for the many without having been fully informed of and consenting to the risks....well, that's a tragedy and it's unethical, especially since most will be kids. Of course vaccines are highly associated with neuro-immune and xmrv related disease....discovering exactly what that connection is will take a little more time...but we will find out.
