Health Minister Martin Foley said most COVID-19 cases are in young people.
"Today, like our general practice and primary healthcare partners, we are of course pleased to expand the vaccine eligibility to anyone aged 12 years and over, and with 585 of the current active cases aged 19 or younger, the importance of vaccinating teenagers is clearly very strong," he said.
He said 529 of the active cases are under the age of nine years.
