Ah I admit I didn't read the "methods" section in much detail, because I saw you made a couple of mistakes and stopped taking the argument seriously. Upon rereading it, they do mention what you said, namely that maternal antibodies last longer in children of unvaccinated mothers. I corrected my original post for fairness.
Ok, look. You take an extreme militant position saying
all vaccinations are bad, so your opponents (including me) took a position saying
vaccinations are good, which isn't entirely correct, but we believed it to be the easiest way to shut down your argument. The truth is closer to what @
NickNaylor is saying: There are risks and benefits to vaccines, but the benefits far, far outweight the risks (just like any other therapeutic).
So why not do some reading yourself? You posted a clearly biased anti-vaccine article on the small pox vaccine. So I will now post a similarly biased pro-vaccine piece on smallpox as well.
See here.
Also, keep in mind that few people today even consider variolation (deliberately infecting you with smallpox) to be a viable strategy. Also note that smallpox inoculation is not performed in the United States anymore, due to the risks. There is extremely strong evidence that the inoculation is effective, but since it has significant risks, and because smallpox has been eradicated (again, due to vaccination), it is not necessary.
See here for a timeline.
Additionally, note that there is no treatment for smallpox. None! If it returns, people will die
en masse.
The CDC maintains a stockpile of smallpox vaccine in case of an outbreak (a terrorist attack for example). They have been keeping this stockpile for years, and with good reason. The disease is highly contagious, lethal in 30% of cases, cannot be treated, and can only be prevented by vaccine.
See here.
Now for a more fair representation of vaccines, a review on the efficacy and risks of the MMR vacine published in 2011.
See here
The results: Prior to the MMR vaccine, nearly 100% of children were infected with measles. After the vaccination was rolled out, measles cases dropped by 99%.
The mumps has decreased by 99% also.
Note that in other countries were measles is endemic, the mortality rate for measles infection is around 25%.

The review article goes into great detail on the risks. For example, encephalitis was found at around 0.02% in one study, and another study reported 0.4% occurrence of febrile seizures weeks after vaccination.
Nobody is saying vaccination is perfect. However, it is one of those things that has been
so effective in fighting diseases that some diseases have literally been eradicated. It is a major triumph of biomedical science, something that we who have an interest in biomedical science are proud of. You are worried about the risks reported by a tiny minority of cases, but forget that truly dangerous vaccines (smallpox and the oral Polio vaccine) are not carried out because
doctors are not idiots and can recognize risks.
If you are saying we should be wary of the risks of vaccinations, they I agree wholeheartedly. However if you are saying that the few incidents of vaccine-related complications are enough to discredit vaccination in general, don't be surprised people think you are ignorant! Equivalent arguments would be "don't take blood-pressue medication because they have complications," "don't get surgery because it has risks," "don't see the doctor because the doctor might misdiagnose you." Basically, a militant stand against vaccination is a dangerous mentality that threatens
all the progress we have made in biomedical science.
