AstraZeneca’s Acknowledgment of Rare Side Effects Amid Lawsuit
Amid a class action lawsuit in the UK, pharmaceutical giant AstraZeneca has made a significant admission regarding the potential side effects of its COVID-19 vaccine, Covishield. Court documents reveal AstraZeneca’s acknowledgment that Covishield can, in very rare instances, lead to Thrombosis with Thrombocytopenia Syndrome (TTS).
Exploring Thrombosis with Thrombocytopenia Syndrome (TTS)
Thrombosis with Thrombocytopenia Syndrome (TTS) is a rare yet serious medical condition characterized by the simultaneous occurrence of blood clot formation (thrombosis) and low platelet counts (thrombocytopenia). It’s essential to understand the symptoms, diagnosis, and treatment of TTS to effectively address this rare but critical syndrome.
Symptoms of TTS include severe headaches, abdominal pain, leg swelling, shortness of breath, and neurological impairments. Diagnosis involves comprehensive blood tests to evaluate platelet levels and imaging studies, such as ultrasounds or CT scans, to identify blood clots. Managing TTS necessitates a multidisciplinary approach, often involving hospitalization.
Treatment includes the administration of anticoagulants to prevent further clotting and supportive care to address symptoms. Additionally, therapies like Intravenous Immunoglobulin (IVIG) and plasma exchange may be employed to stabilize platelet levels and manage immune-related responses.
Risks and Management of Thrombosis with Thrombocytopenia Syndrome (TTS)
Healthcare providers maintain vigilant oversight of patients diagnosed with TTS due to its potential for severe complications, including organ damage and mortality. Dr. Rajeev Jayadevan highlights TTS’s occurrence in rare instances following specific vaccines, emphasizing the importance of timely recognition and effective management.
WHO’s Recognition of TTS as a New Adverse Event
In its 2023 report, the World Health Organization (WHO) highlights TTS’s emergence as a new adverse event following immunization with certain COVID-19 vaccines. The WHO underscores the importance of raising awareness and providing guidance to healthcare providers for the assessment and management of TTS cases.

Insights into Covishield and TTS
Covishield, developed by AstraZeneca and produced by the Serum Institute of India, has raised concerns regarding its association with TTS. Nearly 90% of India’s population received Covishield, prompting scrutiny of its safety profile. Dr. Ishwar Gilada emphasizes the significance of TTS as a rare but serious adverse effect, with an incidence as low as one in 50,000 (0.002%).
Understanding the Mechanism of TTS
Dr. Ishwar explains the mechanism behind TTS, highlighting the vaccine’s interaction with the bloodstream and platelet factor 4 (PF4). This immune response can lead to blood clot formation, with potentially severe consequences.
Reassurance and Advocacy for Vaccination
Dr. Ishwar reassures recipients of the Covishield vaccine, emphasizing the rarity of TTS and the overall benefits of vaccination. Dr. Rajeev advocates for vaccination, citing its role in preventing COVID-19-related deaths and complications. He underscores the importance of vaccination despite extremely rare adverse effects.
Conclusion: Urgency and Importance of Vaccination
In conclusion, while TTS poses a concern, vaccination remains crucial in combating the COVID-19 pandemic. Continued research, awareness, and vigilance are essential in addressing and mitigating the risks associated with TTS while ensuring the safety and efficacy of COVID-19 vaccines.
