AstraZeneca Admits COVID-19 Vaccine Can Cause Rare Blood Clots

In a significant development, AstraZeneca, the global biopharmaceutical company, has acknowledged that its COVID-19 vaccine can cause thrombosis with thrombocytopenia syndrome (TTS) in extremely rare cases. The admission was made in February 2024 in legal filings with the UK High Court, as part of ongoing lawsuits against the company by individuals who suffered adverse effects after receiving the vaccine.

This admission has far-reaching implications for the global vaccination effort, as it may impact public trust in vaccinations and lead to increased scrutiny of vaccine safety profiles. Moreover, it highlights the need for transparent communication and robust surveillance systems to maintain confidence in vaccination programs.

TTS is a rare disorder characterized by the formation of blood clots (thrombosis) in blood vessels and a low quantity of blood platelets. Dr. Jagadish J Hiremath, founder of the AASRA Group of Hospitals in India, explained that TTS has been identified as an exceedingly rare adverse effect related to certain COVID-19 vaccines, particularly those that use adenovirus vectors, such as the AstraZeneca vaccine (Covishield).

The original lawsuit against AstraZeneca was filed by Jamie Scott, a father of two who developed TTS after receiving the vaccine. Despite surviving the incident, Scott has suffered a permanent brain injury. So far, 51 lawsuits have been launched against the company, demanding damages of an estimated £100 million ($125.36 million).

Dr. Hiremath believes that AstraZeneca's acknowledgment of the relationship between Covishield and TTS may result in increased vaccination safety monitoring and regulatory supervision. However, he also cautioned that this revelation may impact public trust in vaccinations, highlighting the importance of open communication and robust vaccine surveillance systems.

The admission by AstraZeneca has implications beyond the UK, as hundreds of Africans who may have been affected by the company's COVID-19 vaccines may now be eligible to join a class-action lawsuit against the pharmaceutical giant. These individuals originate from countries such as South Africa, Ghana, Côte d'Ivoire, Kenya, Rwanda, and others where AstraZeneca vaccines were used.

Why this matters: The controversy surrounding the AstraZeneca vaccine has not been limited to the UK. Several countries, including Austria, Denmark, Ireland, and Thailand, have previously suspended the use of the vaccine due to concerns over blood clotting. The admission by AstraZeneca may further fuel these concerns and lead to increased scrutiny of thevaccine's safety profile.

Despite the concerns raised by AstraZeneca's admission, health authorities have sought to reassure the public about the overall safety of COVID-19 vaccines. In Kashmir, pulmonologists have come forward to allay fears, emphasizing that there are no proven side effects of the Covishield vaccine and urging people not to panic. Dr. Rafi Ahmad Jan, Head of the Department of Pulmonary Medicine at GMC Anantnag, stated, "We have not proved whether the side effects are that of Covishield, which was a non-live vaccine. There is no hard evidence on it."

AstraZeneca's acknowledgment of the rare blood clotting side effect associated with its COVID-19 vaccine has significant implications for ongoing legal proceedings and public trust in vaccinations. While the admission may lead to increased safety monitoring and regulatory oversight, it also underscores the importance of transparent communication and robust surveillance systems to maintain confidence invaccination programs. As the global fight against the pandemic continues, striking a balance between vaccine safety and the urgent need for widespread immunization remains a critical challenge.
