This report backs up the opinion I've held for some time: They're unnecessary.
As The Journal of Pediatrics states:
“… the largest historical decrease in morbidity and mortality caused by infectious disease was experienced not with the modern antibiotic and vaccine era, but after the introduction of clean water and effective sewer systems.”
The Department of Community Medicine out of the UK published a report in The Lancet, claimed to be a "premiere medical journal", states:
“There was a continuous decline [whooping cough deaths], equal in each sex, from 1937 onward. Vaccination, beginning on small scale in some places around 1948 and on a national scale in 1957, did not affect the rate of decline if it be assumed that one attack usually confers immunity, as in most major communicable diseases of childhood. … The steady decline of whooping cough between 1930 and 1957 is predictive of a linear exponential decay characteristic of a general and progressive lessening in the volume and spread of infection among the susceptible population. With this pattern well established before 1957, there is no evidence that vaccination played a major role in the decline in incidence and mortality in the trend of events.”
Not included in this report is something I have recently come upon. It's a quote by the Pediatrician Robert Mendelsohn:
"There has never been a single vaccine in this country (The United States) that has ever been submitted to a controlled scientific study...that means if you want to be kind you will call vaccines an unproven remedy. If you want to be accurate, you'll call people who give vaccines 'quacks'."
While I read the above in a book I'm reading, I also found this article written by Dr. Mendelsohn, which gives his further observations into not only the unnecessary use of vaccines, but to their dangers.
If you're still on the fence, consider the following ingredients which are found in the most common of childhood vaccines of Diptheria, Whooping Cough and Tetanus. You certainly wouldn't knowingly feed your child, let alone yourself, a food item that contained any of these agents.
1) sodium hydroxide (which is also found in bath, toilet and oven cleaners)
2) formaldehyde (apparently not just used by funeral homes)
3) hydrochloric acid
5) thimerosal, which is made of a combination of ethylene glycol, ethanol, thiosalicyclic acid, sodium hydroxide and ethyl mercuric chloride.
6) phosphates (those substances found in laundry and dish detergents that are known to kill sea life)
