NPHET's modelling on the direction the spread of Covid could take over the coming months, didn't take into account changes to the vaccine roll-out.
It means the models cabinet used to make its decision on delaying re-opening of indoor dining, were out of date.
Taoiseach Micheál Martin told Ministers on Tuesday they included the changes to the vaccine roll-out that will allow younger people to access AstraZeneca and Johnson & Johnson.
However, CMO Dr Tony Holohan told opposition TDs yesterday, the modeling did not take into account a faster vaccine roll-out.
