Let's take a look at the total number of CBP "encounters" in fiscal year 2024. According to their own statistics, this was 2.9 million. https://www.cbp.gov/newsroom/stats/cbp-enforcement-statistics-fy2024 For the sake of this exercise, for every encounter, let's assume that one illegal immigrant evaded an encounter ("get aways") while crossing the US border. This would give us a gross number of 5.8 million. I think the majority of the illegals come from Latin America, so let's take a look at measles vaccination rates in this region. https://www.theglobaleconomy.com/rankings/measles_immunization_rate/Latin-Am/ While some countries' MMR vaccination rates exceed the US's (91%), many are lower, including some of the larger sources of illegal migrants. But for this exercise, let's take Mexico at 80% as kind of a weighted average just for discussion purposes. If we accept these estimates, that would mean that of 5.8 million encounters plus "get aways" roughly 20% or 1,160,000 would be unvaccinated. Going back to the number of US citizens visiting this region of about 45 million and an unvaccinated rate of 9%, we get a total of 4,050,000 unvaccinated American visiting Latin America. Unvaccinated American visiting Latin America outnumbers by almost four to one the number unvaccinated illegals entering the US in this scenario.
