The Department of Education is planning for a full return to schools from next month, according to the Minister.
Despite a commitment to keep schools open earlier this year, there was a closure due to the spread of Covid-19 in January.

The HSE's vaccine portal will open for 16-18 year olds in the coming days.
Minister Norma Foley says there are measures being put in place to keep students and staff safe
