Risk Of Dying From Covid-19 40 Times The Risk Of Rare Blood Clot After Receiving J&J Vaccine
The risk of dying from Covid-19 is 40 times the risk of developing a rare blood clotting condition after getting the Johnson & Johnson vaccine, a CNN analysis shows. The US Centers for Disease Control and Prevention said Wednesday it has received reports of 28 people who have developed a rare blood clotting syndrome out of 8.7 million given J&J's Janssen coronavirus vaccine. Three of them have died from the condition, known as thrombosis with thrombocytopenia syndrome (TTS). (McPhillips and Fox, 5/12)

Blood Expert Says He Found Why Some Covid-19 Vaccines Trigger Rare Clots
In Germany, one researcher thinks he has found what is triggering the clots. Andreas Greinacher, a blood expert, and his team at the University of Greifswald believe so-called viral vector vaccines—which use modified harmless cold viruses, known as adenoviruses, to convey genetic material into vaccine recipients to fight the coronavirus—could cause an autoimmune response that leads to blood clots. According to Prof. Greinacher, that reaction could be tied to stray proteins and a preservative he has found in the AstraZeneca vaccine. (Pancevski, 5/13)

Mixing Covid-19 Vaccines Tied To More Side Effects, Early UK Data Suggests
People who got mixed doses of coronavirus vaccines -- receiving a different vaccine type as a second dose than the first dose -- appear to be more likely to experience mild side effects such as fever, chills, fatigue or headache, researchers in the UK reported Wednesday. But the side effects following mix-and-match vaccinations were short-lived and there were no other safety concerns, the researchers reported in the Lancet medical journal. (Howard, 5/12)
