herd immunization works only in terms of children able to get vaccinated. What these anti vaccine people are failing to think of are the children (and adults) with compromised immune systems and infants! infants can not be vaccinated until 6 months. these people are exposing these babies to an extremely dangerous illness that their immune systems are not yet strong enough to handle. It is very self centered and not thinking of anyone else.
Schools are not allowing unvaccinated kids to come to school which means these irresponsible parents are most likely taking them out in the community during the day so they can keep doing their errands and living life thereby spreading the disease even more. While the rest of us with children that either are unable to get vaccinated because of illness or age are stuck in our houses.
