There have been 257 reports made to the Health Products Regulatory regarding suspected side effects of covid-19 vaccines.
Approximately 94 thousand people had received the vaccine at that point.
Of the reports notified to the HPRA, the most commonly reported suspected side effects are in line with those typically associated with vaccination.
They included dizziness, headaches, weakness, pain in the injection area and nausea.
Other suspected side effects reported to the HPRA in small numbers included facial paralysis.
Sinead Curran from the HPRA says they've also had some reports of allergic-type reactions.
The HPRA plans to regularly report the number of people who notify them of a suspected side effect. It expects this number to increase as more people are vaccinated and as it actively encourages people to report suspected side effects as part of its safety monitoring process.
