AstraZeneca’s COVID Vaccine Linked To Another Fatal Blood Clotting Disorder

New Delhi: After Thrombosis with Thrombocytopenia Syndrome (TTS), it has now been found that British-Swedish pharma giant AstraZeneca’s COVID-19 vaccine, made in collaboration with Oxford University can raise the risk of Vaccine-Induced Immune Thrombocytopenia and Thrombosis (VITT) , a rare but fatal blood clotting disorder, claimed researchers. While not new, VITT emerged as a new disease following adenovirus vector-based Oxford-AstraZeneca vaccine sold as Covishield in India and Vaxzevria in Europe at the height of the COVID pandemic in 2021, IANS reported.

“An unusually dangerous blood autoantibody directed against a protein termed platelet factor 4 (or PF4)” was found as the reason for VITT.

In separate research in 2023, scientists from Canada, North America, Germany and Italy described a virtually identical disorder with the same PF4 antibody that was fatal in some cases after natural adenovirus (common cold) infection.
