AstraZeneca has made the significant admission in court documents, acknowledging for the first time since the rollout of its COVID-19 vaccine.

Lawsuit Against AstraZeneca

According to a report by The Telegraph, Jamie Scott, a father of two, filed a lawsuit last year after experiencing a blood clot that left him unable to work. Scott allegedly suffered a permanent brain injury after receiving the COVID-19 vaccine in April 2021.

Jamie Scott's case, along with others, underscores the significant consequences of a rare side effect known as Thrombosis with Thrombocytopenia Syndrome (TTS). This condition is characterized by the formation of blood clots and low platelet counts.

AstraZeneca has conceded in legal documents submitted to the UK High Court that its vaccine "can, in very rare cases, cause TTS." After prolonged legal disputes, this admission could result in significant compensation payouts if AstraZeneca acknowledges vaccine-induced illness or death in specific cases.

What is Thrombosis With thrombocytopenia syndrome (TTS)? 

Thrombosis with thrombocytopenia syndrome (TTS) is an extremely rare condition characterized by the combination of blood clots (thrombosis) and a low platelet count (thrombocytopenia). This syndrome is also known as vaccine-induced immune thrombotic thrombocytopenia (VITT).

Thrombosis refers to the formation of a blood clot, which can impede normal blood flow within a blood vessel. Thrombocytopenia is a condition marked by a deficiency of platelets in the blood. Platelets play a crucial role in blood clotting, helping to prevent excessive bleeding when injury occurs.

Thrombosis With thrombocytopenia syndrome (TTS) Symptoms

Symptoms of thrombosis with thrombocytopenia syndrome (TTS) can vary depending on which part of the body is affected. Here's a breakdown of the symptoms:
