The National Public Health Emergency Team has said it has "noted" that people aged 70 years and older will not all have received their first dose of Covid-19 vaccine until "after mid-April" and will not have got their second dose until "after mid-May".
The issue is raised in the most recently published letter from the Deputy Chief Medical Officer Dr Ronan Glynn to Minister for Health Stephen Donnelly.
Dr Glynn said it highlighted the particular vulnerability of this group over the coming months. On 11 February, the Minister for Health said that it would be mid-May before those aged 70 and older were fully vaccinated.
