Those who don't register for a Covid-19 vaccine before May 10 could then have to wait eight weeks for their jab.
That's according to Health and Social Care Minister, David Ashford MHK, who issued the message at this afternoons Covid-19 briefing from government.
He's once again urged all under 30s to get registered for a vaccine as soon as possible.
Mr Ashford says the waiting period will be down to the level of vaccine supplies from that date.
