'); The gap between two doses of the AstraZeneca vaccine can be reduced from 12 weeks to eight, the National Immunisation Advisory Committee (NIAC) has advised. Responding to the new advice from the NIAC Labour TD Ged Nash said what the people of Louth and East Meath will want to know is if it will be implemented. The Louth TD backed the call from Labour Leader Alan Kelly for the Minister for Health to provide clarity, especially for those in the 60-69 age cohort. He said:“This is a welcome development from NIAC but we need clarity on whether the shorter eight week gap between doses will now be implemented?
