6. Condition Can Occur Even After Immunization

Another dangerous aspect of this disease is that it can occur even after you or your child have been immunized. It’s important to understand that it’s impossible for a vaccine to be wholly effective. While these shots will provide you with high amounts of protection from the disease, vaccines depend on widespread immunity for them to be effective. When a high percentage of the students in a school are vaccinated, this helps to protect those who have yet to receive immunization from an outbreak occurring. A single dose is calculated to provide around 85 percent protection with a second dose upping this percentage to 95. However, the vaccine will automatically fail with a small subset of individuals.
