are vaccinated but it doesn't mean there's zero risk with vaccination - read the fine print. The hardest part to deal with is these people taking exploiting herd immunity. Most of us take the risk with vaccines for ourselves and our children (albeit a minor risk) and because we don't carry it, they don't worry about it. The other hard thing to stomach is the immunocompromised people in this world. Most people don't die from measles but the can sure pass it on along with a whole host of other issues to people much less suited to fight off diseases.
