Earlier, the CEO of the HSE, Paul Reid, told an Oireachtas Committee on Health that 1.1 million vaccine doses are likely to arrive in Ireland during the first quarter of the year, which is less than the 1.24 million that was expected.

He said that there has been "high levels of frustration" related to the supply problems, however this has been an EU-wide problem, and he expects things to improve in the second quarter.
