Frequently Asked Questions

Yes, people born before 1957 are considered immune to measles, and providing documentation of a date of birth earlier than 1957 is sufficient proof of immunity for employees who are not medical providers. However, any medical provider - including school nurses - must have two MMR vaccines, regardless of birth date. A date of birth before 1957 will not be enough to avoid exclusion for medical providers if there is a measles exposure at their location.

If someone provides paperwork signed by a licensed healthcare provider that says their serology/bloodwork shows immunity, a second immunization is not needed.

The MMR takes up to two weeks to be effective, so if someone received the MMR vaccine and did a titer within two weeks, the titer may not show full immunity.

The MMR can take up to two weeks to be fully effective. In addition, if there is a reaction to the MMR vaccine, it can be harder to determine if symptoms are from the vaccine or from the measles virus.

Yes. Unimmunized or under-immunized staff members or substitutes that visited a school during an exposure window must be excluded from any school until after the exclusion window. However, staff at other school buildings where the under-immunized worker spent time do not need to be excluded unless a case occurs at their school.

One dose is sufficient. However, if there has been an exclusion at your workplace (a school or medical practice), you will be excluded for the duration. Keep documentation of all vaccinations and bloodwork to show immunity in the future.
