It comes as 11 cases of the measles have been confirmed in Dublin
Symptoms include high fever, cough, runny nose and red eyes, as well as a red rash that starts on the head and spreads down the body.
Minister Simon Harris says people need to be protected from the disease: "In recent years in this country, we had seen a decline in vaccination rates. I am encouraged that a number of those rates are now increasing again.
