Marysville High School: Keep unvaccinated kids home due to chickenpox outbreak

MARYSVILLE, Mich. (AP) - - A chickenpox outbreak has led a Michigan health department to ask parents of children who aren’t vaccinated to keep them home from school until they’re inoculated.

The St. Clair County Health Department told parents of Marysville High School students in a letter that about 37 “exposed susceptible students” who cannot provide documentation of smallpox immunity will be excluded from attending school and extracurricular activities until 21 days after the last identified case.

The letter says students will be re-admitted to the high school immediately upon getting vaccinated or providing the health department with acceptable documentation of immunity.

It says immunity is defined as documentation of two valid doses of live chickenpox vaccine at or after 12 months of age or laboratory evidence of immunity or confirmation of the disease.
