Because whenever there is a group of people together in a small space like classrooms, there is an increased chance of spreading Infectious Diseases. When more people are immunized against a disease, there is an increase in 'herd immunity'. That is, it's less likely that the disease will appear in that group, even if a few of them are not immunized for whatever reason. Keep in mind that there are people who cannot not get vaccines for medical reasons like allergy. So, if a family chose not to vaccinate their kids for non medical reasons, they not only increase their own risk of getting the disease, they also increase the risks of other children who cannot get the vaccine due to medical reasons.
There is no ban on HPV vaccines. In fact, in some states girls are required to receive HPV vaccines for school.

Vaccines help the immunity systems to stay strong from particular diseases. In the immunity system carries microorganism that recognize the agents as foreign, destroy it and remembers it.

Attenuated vaccines are created by destabilizing the virulence of the strain while still keeping the organism alive. Attenuated vaccines were first developed by Albert Calmette and Camille Guerin in their efforts to use an immunization as a cure for Tuberculosis in 1906.
What year did New York produce school systems?
High school students getting polio vaccines.
Vaccines have a minuscule amount of the disease, so your immune system can easily destroy it and then retain in the immune systems memory the best way to destroy it. That is how vaccines work. However if you have an immune deficiency disorder, or a weak immune system, the disease inside the vaccine has a tiny chance of surviving and reproducing causing the disease to infect you.
Edible vaccines are vaccines produced in plants genetically modified through bioengineering.
