The HSE has confirmed about 850 staff have received too low a dosage of the flu vaccine.
The news comes days after it emerged 489 patients also received too low a dose from pharmacies. Hibernian Healthcare, which trained pharmacists to deliver the vaccines, also vaccinated staff at 11 HSE locations across Dublin Mid-Leinster.
Asked if the HSE would bear the cost of revaccination, Minister for Health Dr James Reilly said the company made the mistake and should bear the cost. President of the Irish Pharmacy Union Darragh O’Loughlin said the incident “raised questions around the design of the vaccination syringe”.
