The "community immunity" principle in operation:

When a critical portion of a community is immunized against a contagious disease, most members of the community are protected against that disease because there is little opportunity for an outbreak. Even those who are not eligible for certain vaccines -- such as infants, pregnant women, or immunocompromised individuals -- get some protection because the spread of contagious disease is contained. This is known as "community immunity."

[IchBinEinBerliner]

Are you an infant, pregnant woman, or immunocompromised individual?

Further, if you are a infant you can thank a vaccine for reducing the time you have immunity provided by your mother via breast feeding.(A woman who had measles provides immunity to her baby via breastfeeding for 12-15 month. A vaccinated woman only provides immunity for 6 months). http://www.vaccinationcouncil.org/2014/06/24/measles-and-measles-vaccines-fourteen-things-to-consider-by-roman-bystrianyk-co-author-dissolving-illusions-disease-vaccines-and-the-forgotten-history/

If you are pregnant, why did you not get your vaccines as a child?

If immunocompromised, have you been so since birth? If not, then why did you not get your immunizations as an infant? Additionally, if you are immunocompromised, you are susceptible to any disease not just viruses that have a vaccine available. You should reduce your exposure to the public regardless.

If you are none of the above, aren't you just someone who wants to make other make the same medical decisions as you?

On a side note, I just got a head cold from a vaccinated petri dish(ie a person) last week. It is the first illness I have had in three years. Even the vaccinated can carry diseases.

What percentage of the populace must get vaccinated in order to provide herd immunity?
(A John Hopkins study from 1993 states between 70-95% depending upon the virus http://www.op12no2.me/stuff/herdhis.pdf ).

Along those lines, here are excerpts from CDC reports on recent measles outbreaks. I have mostly included the numbers of vaccinated that have been infected, They would not be the at risk class indicated in herd/community immunity picture that you cited since they in fact have been vaccinated. What is the explanation for such a high rate of failure in their immunization?

Eleven (19%) patients had documentation of 2 or more valid doses of measles, mumps, and rubella (MMR) vaccine, including two children and nine adults. Three health-care personnel had documentation of serologic evidence of immunity before exposure, and one additional patient was found to have serologic evidence of immunity when tested as part of a contact investigation before symptom onset.

or who had an unknown vaccination status (58 [20%]); 30 (10%) were in persons who were vaccinated

Given the 90+% vaccination rate with MMR(the 20% of unknown are likely 18% vaccinated) for a grand total of 28% vaccinated getting the illness.

three had received 1 dose of measles-containing vaccine, and one had received 2 doses.

Among the 110 California patients, 49 (45%) were unvaccinated; five (5%) had 1 dose of measles-containing vaccine, seven (6%) had 2 doses, one (1%) had 3 doses, 47 (43%) had unknown or undocumented vaccination status, and one (1%) had immunoglobulin G seropositivity documented, which indicates prior vaccination or measles infection at an undetermined time.

Among the 45 U.S. residents aged 12 months−19 years who acquired measles, 39 (87%) were unvaccinated
That means 13% were vaccinated.

http://www.cdc.gov/mmwr/preview/mmwrhtml/mm6236a2.htm

Thirteen (8%) of the patients had been vaccinated, of whom three had received 2 doses of measles, mumps, and rubella (MMR) vaccine.

Given that community/herd immunity for measles requires a immunity base greater than 92%( http://www.ovg.ox.ac.uk/herd-immunity ). How do you achieve community immunity with a vaccine that fails to provide immunity up to 19% of the time?
