The health products regulatory body has issued a safety update about the number of side-effects experienced by people who received vaccinations for Covid-19.
It said that up to 13 May, fewer than five Irish people who had received vaccinations experienced very rare blood clotting events in in the brain in combination with low blood platelets.
These unusual blood clotting events are referred to as thrombosis with thrombocytopenia syndrome. They were the key side effect recently investigated by the European Medicines Agency, whose study resulted in NIAC’s earlier recommendation to limit the use of the AstraZeneca and Johnson & Johnson vaccines to people over the age of 50 in Ireland.
