The reality is that we eradicated these diseases so there's no longer a need for vaccinations.  the reality is that 'we eradicated' many diseases due to sanitation and hygieny, and due to the fact that infectious diseases change over the generations.  200 years ago, measles had a fatality of 20%, nowadays, it only kills the very weak, infants without maternal protection and seniors who hadnt encountered it in childhood .  Now that migrants, infected with diseases we haven't seen in decades are jumping our borders and bringing the old diseases back.  vaccination, suppressive medicine (antibiotics for every cough), over-hygieny, and constant intoxication have compromised the immune system of a majority of people in the western world. now, we are too weak to fight these new or old pathogenes the migrants bring. all part of the plan.
