CA has one of the strictest vaccination laws. There are less unvaccinated people in CA than in other states which still allow philosophical and religious exemptions.
Measles used to be considered as common and harmless as the common cold in the 50s. It’s not a big deal.
I'm pretty sure that the viruses they use in vaccines are dead or otherwise incapable of infection, otherwise, we should be seeing a fuckton more outbreaks.
And attitudes in the past can be wrong, especially if they didn't fully understand it.
It strongly depends on the vaccine. Some vaccines work well enough by just introducing synthetically-created proteins that are identical to the virus' external shell + something to trigger your immune system to tell it that it should respond that the strange proteins introduced to your body.
Other vaccines rely on introducing a live-attenuated virus (LAV). This is basically a virus that has been intentionally modified to reduce its virulence and infectivity yet still maintain enough potency to educate the immune system. These are still considered quite relevant - perhaps even superior - as this kind of vaccine mimics the virus a lot better (obviously), including tissue preference and all that jazz.
Naturally this is also why people with derailed immune systems can't get vaccinated. A vaccine
requires an immune response. If people's immune system can't respond even a weakened version of the virus might be dangerous.
There are rare cases where vaccine-associated measles may occur, as was addressed above by The Free Joy State.

Most of the outbreaks occur infecting mostly people (including children) who already got vaccinated against the disease.

I get the impression Indig0's mind has been made up and they don't care for nuance - just pressing their point.
Yes, there are cases where a vaccine's effectiveness wears off - this depends on several factors, however. The type of vaccine, first of all. The amount of doses you receive determines whether you develop and sustain protective immunity. Inter-individual variation also impact the success rate. Let's not forget people are more variable than they think - how you respond to the same dose of a vaccine may not be the same as how I respond to it. Proper follow-up to vaccination is required - this is something doctors should emphasize to parents and something parents should ensure.
A vaccine is eliminated from your body, so it all lies with your immune system. If something causes your immune system to "forget" it's adaptation, you should take measures to "re-educate" it.
Pretending this applies to all people is intellectually dishonest.
