AstraZeneca Admits Rare Side Effects in Covishield Vaccine


In a significant development, British-Swedish pharmaceutical giant AstraZeneca has made a startling admission regarding its COVID-19 vaccine, Covishield. The vaccine, which was widely administered in India and developed in collaboration with the University of Oxford, has been linked to a rare side effect known as Thrombosis with Thrombocytopenia Syndrome (TTS).

What is TTS?

TTS is a serious and life-threatening condition characterized by the formation of blood clots (thrombosis) coupled with low platelet counts (thrombocytopenia). Individuals affected by TTS may experience symptoms such as severe headaches, abdominal pain, leg swelling, shortness of breath, and neurological deficits. Prompt recognition and management are crucial for improving outcomes in those impacted by this rare but critical syndrome.

AstraZeneca’s Admission

AstraZeneca is currently facing a class action lawsuit in the United Kingdom, with 51 cases filed against the company. In court papers, AstraZeneca has conceded that Covishield can, in very rare instances, cause TTS. This admission comes as health experts and regulatory bodies continue to scrutinize vaccine safety2.

Treatment and Awareness

For individuals diagnosed with TTS, treatment involves a multidisciplinary approach. Hospitalization, anticoagulation therapy to prevent further clotting, and supportive care are essential components of management. Intravenous immunoglobulin (IVIG) and plasma exchange may also be utilized to stabilize platelet levels and manage immune-mediated reactions.

The World Health Organization (WHO) has issued interim emergency guidance to increase awareness about TTS in the context of COVID-19 vaccination.

Covishield’s Journey

Covishield, produced by the Serum Institute of India, played a crucial role in India’s vaccination drive. However, this recent revelation underscores the importance of ongoing surveillance and transparency in vaccine safety assessments. As the global community continues to combat the pandemic, understanding and addressing rare side effects remain paramount.

AstraZeneca’s acknowledgment of Covishield’s potential side effects serves as a reminder that vaccine safety monitoring is an ongoing process. Public health authorities and healthcare professionals must remain vigilant and communicate transparently to ensure public trust and confidence in vaccination programs.

As the scientific community grapples with the delicate balance between vaccine benefits and risks, the spotlight remains on Covishield and its impact on global health. The pursuit of safe and effective vaccination strategies continues, guided by evidence-based research and open dialogue.
