Pharmacists have complained they have been given no details about told when they will be vaccinated or when they will begin vaccinating the public.
The Irish Pharmacy Union (IPU) has complained of being "sidelined" by the Department of Health and the HSE.
The Government announced last week that it had agreed a €91m deal with pharmacists and GPs to administer the vaccines, but so far pharmacists have received no details about their involvement or role, according to IPU chief executive Darragh O'Loughlin.
"We've heard nothing specific about when pharmacy teams will be vaccinated or when pharmacies will be rolling out vaccination to patients and the public," he said.
"This is leading to huge frustration and annoyance among pharmacists and staff. Pharmacists feel sidelined by the Department and the HSE and their goodwill is eroding."
Mr O'Loughlin, who believes pharmacists could administer 80,000 vaccines a week, said yesterday that the IPU had been told verbally, without being given a reason, that they would not be involved in the roll-out to the over-70s.
The Department of Health and the HSE, whose officials are due to meet with the IPU today, did not respond to queries last night.
