AstraZeneca Covid 19 Vaccine: Researchers have claimed that the Covid-19 vaccine of British-Swedish pharma giant AstraZeneca, developed in collaboration with Oxford University, has been found to have an increased risk of immune thrombocytopenia and thrombosis (VITT). This is a serious condition in which a blood clot forms.
In fact, at the peak of the Covid pandemic in 2021, VITT has emerged as a new disease after the adenovirus vector-based Oxford-AstraZeneca vaccine sold as Covishield in India and Vaxjavria in Europe. Dangerous blood autoantibodies to platelet factor 4 (PF4) have been found to cause VITT.
Flinders University research revealed
According to news agency IANS, in separate research in 2023, scientists from Canada, North America, Germany and Italy uncovered a disease with similar PF4 antibodies, which in some cases occurs after natural adenovirus (common cold) infection. It was fatal. Now in a new research, Flinders University in Australia and other international experts found that the PF4 antibody in both adenovirus infection-associated VITT and classic adenoviral vector VITT has the same molecular structure.
What did Flinders professor say?
Flinders Professor Tom Gordon said that in fact the way lethal antibodies are formed in these disorders is similar. The researcher said that our solutions are applicable to rare cases of blood clotting after VITT infection, it also works on the development of vaccine. The same team had discovered the molecular structure of PF4 antibody in a research of 2022. Also a genetic risk was identified.
The report was presented in the High Court
The new findings, published in the New England Journal of Medicine, suggest important implications for improving vaccine safety. This research comes after AstraZeneca admitted in a legal document submitted to the High Court in February that its Covid vaccine can cause thrombotic thrombocytopenic syndrome (TTS) in very rare cases.
What is TTS?
TTS is a rare side effect that can cause blood clots and low platelet counts in people. It has been linked to the deaths of at least 81 people in Britain. The company has also voluntarily withdrawn its Covid vaccine from Europe and other global markets.
