The following contains approximately 100 scientific studies that at the very least should indicate that the vaccine debate is far from settled.
This compilation of studies is geared towards those who are largely convinced that "the science is in" regarding the safety and efficacy of all vaccines.
This is also not intended to be a gish gallop. The subject of vaccination is extremely nuanced and complex, and absolutely deserves a detailed, in depth discussion.
I've tried to present this material in as concise a manner as possible. Those that dismiss this information without careful consideration are doing this entire topic, and themselves, a great disservice.
This material is not meant to dissuade people from receiving vaccines, nor is it meant to demonstrate that all vaccines are harmful and ineffective.
Rather, the goal is create an impetus for a renewed conversation on an extremely important topic that affects the lives and well-being of future generations.
Although this information was compiled from a variety of sources, two books in particular proved to be indispensable: Miller's Review of Critical Vaccine Studies by Neil Z. Miller, and Dissolving Illusions by Suzanne Humphries.

Here are the different sections of Part II:
Pushing Pertussis
The first pertussis vaccine was introduced in the 1930's to treat whooping cough.
The pertussis vaccine has encouraged evolutionary adaptation, permitting virulent vaccine-resistant strains of pertussis to emerge.
People who are vaccinated against pertussis may be silent carriers of the disease and capable of infecting others. For example, baboons vaccinated against pertussis became carriers and spread the disease.
Because people who are vaccinated against pertussis can still spread the disease, herd immunity and eradication are virtually unattainable:
Fully-vaccinated children are still susceptible to pertussis:
Since protection after vaccination wanes within 2 to 4 years, “lack of long-term protection after vaccination is contributing to increases in pertussis among adolescents.”
New strains of pertussis toxins have emerged subsequent to pertussis vaccination:
The vaccine is not effective against these virulent new strains:
Since Pertussis has “no non-human hosts or environmental niche, vaccine-mediated immunity is the most likely selective pressure against Bordetella pertussis.”
Pertussis vaccine failures are due to genetic changes in pertussis strains and poor efficacy, not because too many people are unvaccinated.
When the acellular pertussis vaccine (DtaP) replaced the whole cell pertussis vaccines (DTP) in the 1990s, the World Health Organization created an official standard method to define cases of pertussis.
The new definition was excessively restrictive, requiring laboratory confirmation and at least 21 days of paroxysmal cough. As a result, legitimate cases of pertussis were eliminated and the efficacy of the vaccine was artificially inflated.
Acellular pertussis vaccines are designed to protect against pertactin, however, pertactin-negative mutations have emerged in Japan, France, Finland, Australia and the United States.
DtaP vaccination to protect children from B. pertussis increases their risk of whooping cough from B. parapertussis.
Another study concluded that "aP vaccination interferes with the optimal clearance of B. parapertussis and enhances the performance of this pathogen," resulting in "an approximately 40-fold increase in B. parapertussis lung colony-forming units."
Pertussis vaccines also do not protect against whooping cough caused by B. holmesii.
The imperfect immunity given by pertussis vaccines is causing outbreaks of whooping cough in highly vaccinated populations:
