In trying to balance public safety vs. personal choice, you have started out with the assumption that if vaccinations were to cease today, or levels of vaccination compliance were to fall below a certain point, there would be increases in both the morbidity and mortality of infectious diseases. This has simply not been shown to be the case. Yes, there may be an increase in the reported cases of these illnesses, but almost every study done on the actual severity and mortality from these diseases have shown that both hospitalisations and deaths declined when the vaccination rate declined. I will list several citations, but there are many, many more. Not only that, but in countries like the USA with mandated high levels of vaccination, there have been increases in many of these diseases with, for instance, whooping cough in the mid 1990's increasing to levels above those of the mid 1960's - years before mandatory vaccination.
Every parent wants what is best for their child.
Every parent wants to protect them from the dangers of the world. Every parent has a right to make free and informed choices of the best ways to go about providing that protection. Events of recent weeks with hearings on the dangers of anthrax vaccines, hepatitis B vaccines and the withdrawal of the rotavirus vaccine after it's very recent approval, have shown that vaccination may not be the best way to go about providing that protection for every child. In much the same way as the tobacco companies and medical organisations claimed for decades that cigarettes were not dangerous to the health, pharmaceutical companies and medical organisations like the AMA and the American Acadamy of Pediatrics are now claiming that vaccines are safe, effective and necessary. These claims are not backed up by the published medical literature.
