Understanding the Serious Side Effects of the Covishield Vaccine

The Covishield vaccine, developed by British pharmaceutical company AstraZeneca in collaboration with the University of Oxford, has been widely administered in India to protect against COVID-19. However, recent reports have raised concerns about serious side effects associated with the vaccine, including blood clotting and fatalities.

Serious Side Effects and Legal Actions:

AstraZeneca, the manufacturer of the Covishield vaccine, has admitted in court that the vaccine can have serious side effects. The British newspaper, The Telegraph, reported that the company is facing legal action due to allegations of blood clotting and other severe problems associated with the vaccine. One such case was filed by Jamie Stock in the UK, who suffered permanent brain injury after receiving the AstraZeneca vaccine. The condition, known as TTS (Thrombosis with Thrombocytopenia Syndrome), involves the formation of blood clots in the brain and a decrease in platelet count, potentially leading to brain stroke or cardiac arrest.

AstraZeneca’s Response:

AstraZeneca initially denied the link between the vaccine and TTS, but later acknowledged that the vaccine could cause TTS in rare cases. The company submitted documents to the court, stating that 51 cases have been registered against them in the UK High Court. AstraZeneca claims that TTS can also occur without the vaccine and that the benefits of the vaccine outweigh the risks. They assert that the vaccine has saved the lives of millions of people worldwide during the COVID-19 pandemic.

Expert Opinion:

Dr. Ishwar Gilada, an infectious disease specialist, provides insights into the risks associated with the Covishield vaccine. He explains that when a new drug or vaccine is developed, it undergoes various stages of testing, including lab trials, animal trials, and human trials. However, due to the emergency nature of the COVID-19 pandemic, the Covishield vaccine received emergency use authorization based on Phase 2 trials. Dr. Gilada emphasizes that while the vaccine may have serious side effects, it is crucial to consider the balance between its benefits and risks. He compares the situation to a building on fire, where jumping to safety may result in a broken bone but ultimately saves lives.

Current Status and Recommendations:

Following reports of serious side effects, the British government halted the use of the AstraZeneca vaccine. However, the Indian government and some other governments have not suspended its use but have imposed restrictions. Dr. Gilada advises individuals who have received the Covishield vaccine to monitor their health and seek medical attention if they experience any concerning symptoms. He also encourages individuals to differentiate between side effects caused by the vaccine and those resulting from other factors such as aging or long COVID. If there is a suspicion of vaccine-related side effects, individuals are advised to consult a healthcare professional and consider legal action if necessary.


The Covishield vaccine has been associated with serious side effects, including blood clotting and fatalities. AstraZeneca, the manufacturer, has acknowledged these risks and is facing legal action. However, it is important to consider the overall benefits of the vaccine in saving lives during the COVID-19 pandemic. Individuals who have received the vaccine should remain vigilant and seek medical advice if they experience any concerning symptoms. The decision to take the vaccine should be based on a thorough understanding of the risks and benefits, as well as consultation with healthcare professionals.
