A class action lawsuit has been filed against AstraZeneca in the UK after court documents revealed that the company's Covid vaccine, Covishield, can cause a rare side effect known as TTS. This condition, characterized by blood clots and low platelet count, has resulted in serious injuries and deaths for some patients who received the vaccine. Despite the company's admission, AstraZeneca maintains that the vaccine is not "defective" and that TTS can occur even without vaccination. The lawsuit seeks damages of up to 100 million pounds from the pharma giant.
