Priority cases for measles immunisation in Northland has been widened to include people aged over 30 years who are vulnerable, including frontline healthcare workers and teachers.
There have been 64 confirmed cases of measles in Northland while three others were under investigation, and the Northland District Health Board said those most vulnerable should be immunised.
Nationally, the number of confirmed cases has surpassed 1500 while two unborn babies have died after their mothers caught measles during the recent outbreak of the disease.
The current immunisation priorities in Northland are those at 15 months and 4 years, one dose for under 30s who haven't previously had one, and people between 30 and 50 years old based on clinical judgment.
They must be immunocompromised, live with someone who is unable to be immunised, are frontline healthcare staff or a teacher at a primary or secondary school.
