There is a lot of muddy thinking in this stream. First immunity malfunctions like colitis,asthma,and hay fever are a different category of human maladies than infectious diseases. Humans mostly survive and function with immunity disorders. People die from infectious diseases!
As mentioned in an earlier post millions of people die from pandemics like the Spanish flu http://www.neatorama.com/2009/04/27/5-deadliest-pandemics-in-history/
. For those born after the introduction of vaccinations for polio, many my age died or were crippled by polio.
Like many arguments there are elements of truth on both sides. Overuse of antibiotics has decreased their efficacy, increase resistance of pathogens and probably compromised the physiology of many people, but immunization has saved millions of lives. For those of you opposed to vaccination, you should educate yourselves on risk management. Further, since those of you who think your decision to not have your children vaccinated is your own freedom of choice. Think again. To quote the the old adage:" your freedom to swing your arm ends at the end of my nose". If the pool of unvaccinated members of a population reaches reaches a critical size, a pandemic agent can overwhelm the population, spreading the risk to all, including my own family.
