With us vaccinations end in average at 12 years old if you visit highschool. There was a time after a bite or rusty pin they said you should take a tetanus shot. Just this one nothing else.

Now they also have shots for girls and by now Boys as well to prevent womb cancer or so. It is free choice of you go or ignore.
Children with us being not vaccinated are able to visit school unlike in Hungary.

Might be in the future since the invasion of foreigners bring diseases we haven't dealt with for decennial.

We also learned the older you get the more diseases and therefor higher immune system.

Next to that sick people or those with allergies and chronic diseases are fewer injected simply because every shot is an attack on the immune system putting it at work unnecessary.

No way within the EU every country works the same.
