are you seriously giving life and credence to this lunatic's bullcrap? the Americas (all of it) were declared measles free by the WHO. but yes, measles existed in the rest of the world. so since the central and south American countries are better vaccinated than the US did it come from there? or.. and try and get your far too obviously affected brain around this for just a minute, more likely it was affluent US adults and kids travelling to still affected regions bringing measles and mumps back to the US? The same case for antivaxer affluent Europeans who believed the conspiracy.
You are talking possibilities or small occurances, I am talking about probabilities and at least the majorty of cases.
We know disease importation hurts the Liberal open border narrative, which is why Liberals are aggressively disseminating misinformation on this issue.
