If vaccines are so effective than a person who is vaccinated has no reason to worry about catching a disease from an unvaccinated person. It's that simple.
vaccination has saved the lives of around 20 million people
That's nothing considering there's over 7 billion people most of which aren't vaccinated or at least not nearly to the same extent as in us and w europe.
Is due to exposure to disease carried by countless migrants
No one can deny the fact that the rates of HIV, hepatisis, scabies, even **** like ebola is far higher among middle eastern ans African migrants than native europeans
Good thing atleast in the USA we still have freedom of choice...
