AstraZeneca has robustly defended its vaccine, saying Friday there was "no evidence of an increased risk" of blood clots, and European and UK medicines regulators have each said the link between the vaccine and blood clots has not been confirmed and that rollouts should continue. Prime Minister Boyko Borissov ordered a halt to all inoculation using the AstraZeneca Covid-19 vaccine until the European Medicines Agency "rejects all doubts" about the vaccine's safety, according to a government statement. The moves came in response to reports of blood clots in a few inoculated people in Denmark, including one fatality. The UK's MHRA, where 11 million doses of the vaccine have been administered, said blood clots "can occur naturally and are not uncommon." Polish officials also announced on Friday that AstraZeneca will reduce the number of coronavirus vaccine doses delivered there.
