The biggest problem I see is you ‘guys’ exporting it less well off countries where immunization rates are even lower. see https://en.wikipedia.org/wiki/2019_Samoa_measles_outbreak for how bad it can get

I just wish their ignorance only hurt themselves.

All thanks to declining vaccination rates - particularly among kindergartners, where coverage has dropped below the 95% threshold necessary for herd immunity. Ignorance breeds… well, in this instance, measles becoming endemic in the US once again.

Play stupid games, win deadly diseases.
