      This is because herd immunity is compromised below a threshold, which for measles is extremely high. So a relatively small number of kids who aren't vaccinated can infect quite a few people

      But regardless of this, there is are numerous programs that focus on fixing the other vaccination issues - poverty, lack of access etc - but that doesn't mean that anti-vaccine advocacy is any less of an issue

      Can you two even show that measles vaccines are even capable of producing herd immunity?

      Yes. Since you're a fan of doing your own research, check out Australian immunization rates and cases of endemic vs introduced measles from 2010 to 2018

      You would expect a reduction of cases, at least in the short term, even if the vaccine cannot produce herd immunity.

      That's very simply a nonsensical statement

      No. That's basic math. A vaccine that can prevent symptoms but not infection would result in a reduction of cases, as vaccination rates increase, up until the point that the total number of cases outweighs the suppression provided by the vaccine.

      A vaccine that prevents symptoms but not infection would not reduce cases at all. I assume this is some sort of misunderstanding of the pertussis vaccine, wherein protection against infection wanes over time despite a long-term benefit in terms of symptoms if you are infected

      > A vaccine that prevents symptoms but not infection would not reduce cases at all. Holy shit. SERIOUSLY?! If there are no symptoms, then by definition there are no cases.

      It does, of course, depend on what we're talking about - chronic diseases don't always have specific definitions in the same way infectious diseases do - but a 'case' of infectious disease is almost always characterized as an infection by the pathogen

      Exceptions are where there are multiple sites of infection, for example legionella, but if you have an asymptomatic but lab-confirmed case of, say, hepatitis B, it's still a case

          In the case of pertussis vaccination, people can unknowingly be infected with the disease post-vaccine and be contagious, but never experience significant symptoms. They still have an infection, they just don't know it. They also are unlikely to be caught by monitoring systems

          Disease is also different than infection. In any case, I'm also half asleep and burned out. Let's stop arguing over words. A vaccine may stop expression of symptoms, but not infection. We need to know which is the case with the measles vaccine.
