A draft of the Government's revised vaccine plan aims to see 2.5 million doses delivered by the end of May.
The targets ramp up to four million doses delivered by the end of June and six million by the end of July.
The draft plan going to Cabinet says everyone over 70 will be fully vaccinated next month, with the majority of over-60s getting their first dose in May.

Work on the latest revision of the vaccine plan will continue through the weekend.
An age-based approach will still be at the centre of the plan.
Head of the HSE Paul Reid says the revision will take into account the latest recommendations from the National Immunisation Advisory Committee.
He said: "In essence what we are looking at are the supply of vaccine types we have, and the various ages we will be using them to administer for."
He said it would also take into account the latest NIAC advice around vaccinating pregnant women.
As of Monday, just over 1.4 million doses had been administered in Ireland.
28% of the adult population have received their first dose, and 11% their second dose.
Cabinet is today also considering a plan to significantly ease COVID-19 restrictions during May and June.
Restrictions around hairdressers, barbers, click and collect retail and religious services would be among the first to be eased on May 10th under the plan.
