A significant under-delivery of the Johnson and Johnson vaccine has put the government's vaccination timeline in doubt.
Health Minister Stephen Donnelly says in a best case scenario Ireland will only get half the promised amount of the single-jab vaccine in June.
Around 470,000 doses of the jab were expected in June, as of this morning a 'best case' scenario is that we'd receive half of that.
While the Minister has warned a 'worst case' could be as low as 60,000.
It's expected half of all adults will have been given at least one vaccination by the end of this week.
But Minister Donnelly says the target of 82 per cent of adults getting a jab by the end of June is now in question.
