HSE has recently given a warning to parents in Galway after a mumps outbreak.
After several children exhibited symptoms of the disease, parents of students in a school in the town of Claregalway received notification.
This comes after a few cases reported among young adults in the region, especially between 15 and 29 years of age.
According to RTE reports, HSE advises anyone who is not sure whether there are two doses of MMR vaccine to request additional doses.
The vaccine provides the best protection against infection, but it should be noted that the effect may be up to 28 days prior to entry into force.
It is also recommended that any child with mumps-like symptoms should be kept out of school at least five days after the onset of neck swelling.
Last month, the HSE issued a warning to 45 people in the west of Ireland for seven weeks after having been diagnosed with mumps.
However, experts warn that children can be transmitted to others even before they see swelling, and patients will have other symptoms such as sore throat and cough.
Mumps can also spread through direct contact, such as saliva, through air particles after coughing or sneezing.
