COPENHAGEN, Denmark (AP) — Denmark’s health authorities say they have removed the single-dose Johnson & Johnson COVID-19 shot from its vaccination program to investigate reports of rare but potentially dangerous blood clots. Denmark has already taken the AstraZeneca shot out of its vaccination program for the same reason. Both the J&J and AstraZeneca shots are made with similar technology. The Danish Health Authority said in a statement Tuesday that it “has concluded that the benefits of using the COVID-19 vaccine from Johnson & Johnson do not outweigh the risk of causing the possible adverse effect.”
