AstraZeneca has for the first time officially acknowledged in court documents that its Covid-19 vaccine, sold as Covishield in India and Vaxzevria elsewhere, could cause a rare side-effect called Thrombosis Thrombocytopenia Syndrome (TTS). This comes after a UK-based man, Jamie Scott, was left with a permanent brain injury due to blood clotting and low platelet count after receiving the vaccine. AstraZeneca is now facing 51 legal cases in the UK with victims seeking up to 100 million British pounds in compensation. The company, however, has contested these claims but has accepted that the vaccine can cause TTS in very rare cases.
