The suspension of the use of the AstraZeneca vaccine in Ireland has been proposed by the National Immunisation Advisory Committee.
It came after a report from Norway on serious blood clotting events in adults who received the vaccine.
Irish Deputy Chief Medical Officer Dr Ronan Glynn said the decision was taken “on the precautionary principal”.
The World Health Organisation has said there was no link between the jab and an increased risk of developing a clot.
In a statement on Sunday. Dr Glynn said the new information was received from the Norwegian Medicines Agency on Saturday night.
“It has not been concluded that there is any link between the Covid-19 vaccine AstraZeneca and these cases.
“However, acting on the precautionary principal, and pending receipt of further information, the National Immunisation Advisory Committee has recommended the temporary deferral of the COVID-19 Vaccine AstraZeneca vaccination programme in Ireland.”
In a statement to RTÉ, a spokesperson for AstraZeneca said that an analysis of safety data covering more than 17 million doses of the vaccine administered has shown no evidence of an increased risk of the conditions concerned, and that no trends or patterns were observed in clinical trials.
The NIAC is due to meet on Sunday morning to discuss the issue and will make a statement following the meeting.
