Scientists usually allocate very few grants for research on the safety of vaccinations, adjuvants and other vaccine components. However, there is more than enough money to research why people are not vaccinated, and how to make them vaccinate their children. Therefore, there are many studies characterizing anti-invasive parents.
It is believed that anti-vaccination is usually uneducated, religious and anti-scientific people. However, scientific evidence suggests otherwise. Most anti-vaccines are well-educated and wealthy.
In some private schools in Los Angeles, less than 20% of children are vaccinated. How can it be that these rich and educated people do not vaccinate their children? Do they not know that vaccinations are completely safe, and that they protect against terrible diseases? Or maybe they know something about vaccinations that others do not?
Here are a few studies:
Children Who Have Received No Vaccines: Who Are They and Where Do They Live?
Unvaccinated children are mostly white. Their mothers are over 30, married, have an academic degree, and their families earn more than $ 75,000 a year. (USA)
Effects of Maternal and Provider Characteristics on the Up-to-Date Immunization Status of Children Aged 19 to 35 Months.

The lower the mother's level of education, and the poorer, the higher the chance that she fully vaccinates her children.
More African and Latin Americans are vaccinating their children, and the poorer they are, the more they vaccinate. (USA)
Negative attitude of highly educated parents and health care workers to future vaccinations in the Dutch childhood vaccination program.
Parents with higher education are 3 times more likely to refuse vaccinations.

Deciding to opt out of childhood vaccination mandates.
Public Health Nurs
Parents who do not vaccinate their children, value scientific knowledge, know where to look, and how to analyze information about vaccinations, and at the same time do not really trust medicine. (USA)
Sociodemographic Predictors of Vaccination Exemptions on the Basis of Personal Belief in California.
Am J Public Health
The number of non-medically refused vaccinations in California increased 4-fold between 2001 and 2014 (from 0.77% to 3.15%).
In private schools, there were twice as many refusals as in public schools. The percentage of refusers was higher among white, richer and more educated people.
In other states the same is observed - the percentage of those who refuse vaccinations in private schools is much higher than in public.

More educated parents more often refused HPV vaccines for their daughters. (Canada)
Predictors of HPV vaccine acceptability: a theory-informed, systematic review.
A systematic review of 28 studies showed the higher the level of education of parents, the more often they refused the HPV vaccine.
Factors associated with uptake of measles, mumps, and rubella vaccine (MMR) and use of single antigen vaccines in a contemporary UK cohort: prospective cohort study.
The higher the level of education, age and income, the more often parents refused the MMR, and chose a non-combined measles vaccine. (United Kingdom)
Acceptance of human papillomavirus vaccination among Californian parents of daughters: a representative statewide analysis.

Parents with higher education and conservatives rarely allowed their daughters to get vaccinated against HPV. Parents who did not finish school, Catholics and liberals more often allowed their daughters to have this vaccination. (California, United States)
Maternal characteristics and hospital policies for risk factors for nonreceipt of hepatitis B vaccine in the newborn nursery.

More educated mothers and mothers with higher incomes often refuse to vaccinate their newborn child against hepatitis B. (Colorado, USA)
After Australia passed a law obliging parents to vaccinate children to receive child benefits (No jab, no pay), parents living in rich areas of Melbourne began to vaccinate even less. More educated parents, many with a scientific education, doubt the safety, and the need for vaccinations.
Only 20% of those parents who did not vaccinate before the adoption of this law, began to vaccinate because of it.
10% of Australian parents believe that vaccines are associated with autism. More:

Most of these studies come to the same conclusions. Parents who do not vaccinate their children are older, more educated and more affluent. Please stop treating them like idiots. , , .
And here are some more unusually important studies for which taxpayers' money was used:
Clinician-parent discussions about in fl uenza vaccination of children and their association with vaccine acceptance.
If the doctor says "we will do the flu vaccine today," 72% of parents agree. And if the doctor asks, “are we going to be vaccinated for flu today?”, Only 17% agree.
If a doctor recommends a flu shot along with any other vaccine, then 83% of parents agree. And if the doctor offers a separate flu vaccine, then only 33% agree to do it. Doctors should note.
Greater freedom of speech on Web 2.0 correlates with dominance of views linking vaccines to autism.
The authors of this study analyzed YouTube, Google, Wikipedia and Pubmed, and came to the conclusion that the more freedom of speech on a resource, the more it associates vaccines with autism. Freedom of speech on YouTube is highest, in Google it is less, and in Wikipedia and Pubmed it is very low. This leads to the fact that on YouTube 75% of the videos link vaccinations with autism, in Google 41% of the links, in Wikipedia 14% of the articles, and in Pubmed 17% of the articles link the vaccines with autism (more than in Wikipedia!).
But the worst thing is, the authors note that anti-vaccine activists use scientific arguments (!), Doctors (!), Famous people and personal stories to inspire confidence! The problem is, they write, that YouTube, unlike Google, does not give priority to scientific authorities in search ads.
Doctors participated in 36% of the anti-vaccine ads, and only 28% of the pro-vaccination ads.
The authors of the study propose to moderate the Internet, and also urge medical institutions to be more active there.
A comparison of the use of language in in-formation and anti-vaccination in the response to a high profile Facebook post.
The authors of the study analyzed comments on the post of Mark Zuckerberg on Facebook. They concluded that anti-vaccination comments were more analytical, and were greater in this case. Comments on vaccines were characterized by increased anxiety.
Here the authors analyzed the anti-vaccination movement on Facebook, and concluded that the majority of participants in anti-vaccination groups are women.
Content and Design Attributes of Antivaccination Web Sites.
In this study, the authors analyzed 22 anti-invasive sites, and concluded that anti-vaccination sites are against vaccinations.
Antivaccination activists on the world wide web.
Arch Dis Child
In 43% of queries about vaccinations, search engines showed anti-vaccination sites in the top ten. In Google, 100% of the sites in the top ten were anti-vaccine. More than half of the sites cite doctors who speak out against vaccination. 75% cite "scientific" sources.
The authors conclude that there is a high probability that parents stumble on anti-vaccination materials on the Internet.
Effective messages in vaccine promotion: a randomized trial.
When parents are told about a child having almost died from measles, it only strengthens their belief that MMR leads to serious side effects.
When parents are shown photographs of children with measles, this only strengthens their belief that vaccines lead to autism.
When parents are told the horrors of diseases, this does not affect their intention not to vaccinate children.
When parents are told that MMR is not related to autism, they agree, but their intention to vaccinate their children only decreases.

Influences on Immunization Decision-Making among US Parents of Young Children.
Maternal Child Health J
Parents who know someone whose child has suffered from vaccination rarely vaccinate their children, and more often postpone vaccination until a later date.
Many parents doubt the recommendations of doctors, because they know that doctors should reach a certain coverage of vaccination, and have a financial interest in vaccinations.
Professor of Pediatrics Dr. Carol J. Baker offers a simple solution to the anti-vaccination problem. Since anti-vaccinationers are mostly white and educated, she suggests getting rid of white people in the US.
For all these studies there were grants. But adequate vaccine safety studies, those that lasted more than a few days, and would use a real placebo - there is no money for that.
But you stay there, all the best to you, and be happy!
