A HSE review has found the Beacon Hospital did not consider giving leftover vaccines to higher priority groups before vaccinating teachers from a private school in County Wicklow.
20 teachers from St Gerard's in Bray, were vaccinated at the Dublin hospital in March - during the early stages of the vaccine rollout.
The children of Michael Cullen, the Beacon's CEO, attend the school - with no evidence that St Gerard's had solicited for the jabs prior to the offer.
The reviewer believes it would have been feasible to give the surplus vaccines to groups higher on the sequencing list had they been considered.
