Religion is the main concern for non-vaccination. There are many who believe that vaccinations go against the word of God, such as religious groups in the Netherlands. There are also people who are all in favor of vaccines. “Vaccines are required in California to attend school. If it is against a person's beliefs, they need to be homeschooled (McGreevy).” In the last 10 years there have been many epidemics. For example, just this year there was “a measles outbreak at Disney Land that affected 147 people in the United States; infected people had not received measles vaccinations (NBC news).” If the health department released more information and proved and disproved what vaccines do, more people would be able to make a clear and effective decision about vaccines.
