How do the unvaccinated pose a risk to the vaccinated. If you have the vaccination you are immune,right?
Because there’s a 5 to 10% chance the immunization failed.
If I told you there was a 5% chance a rollercoaster would fail and maim you, would you risk it? I’d rather not have to find out my immunization failed by being exposed to a sick person.
No, even a really effective disease vaccine, like for Measles, isn’t 100% effective. Even if it is 99% effective, imagine one high school with 2000 vaccinated students. One kid comes in with measles, you might end up with 20 cases of measles in vaccinated students. At least 5 of the Disney measles cases were in vaccinated people.
