The wait time between a second Covid-19 vaccine and a booster jab has been reduced from five to three months.
Details were announced last night by Health Minister Stephen Donnelly, following new NIAC advice.
It comes as the Chief Medical Officer warns the Omicron variant now accounts for 11 percent of Covid cases here - up from less than one percent a week ago.
Dr. Christine Loscher, Professor of Immunology at Dublin City University, has said reducing the timeframe between second and third doses is positive.
