A big update has emerged in connection with COVID vaccine and its rare side effects, which are being questioned by several health experts.
British-Swedish multinational pharmaceutical and biotechnology company AstraZeneca has admitted in court papers that its COVID vaccine, Covishield, can cause rare side effect, The Telegraph reported.
What did AstraZeneca say about the vaccine side effect? Currently, AstraZeneca is facing a class action lawsuit in the UK due to claims that its vaccine caused deaths.
In one of the court papers, AstraZeneca has admitted that Covishield can "In very rare cases, cause TTS". TTS stands for Thrombosis with Thrombocytopenia Syndrome.
"TTS is thrombosis with thrombocytopenia syndrome, which is basically clot in blood vessels of the brain or elsewhere, along with a low platelet count. It is known to occur in very rare instances following certain types of vaccines and also from other causes. According to the WHO, adenovirus vector vaccines in particular have been rarely associated with this condition," Medical expert Dr Rajeev Jayadevan told ANI. "Although COVID vaccines have prevented numerous deaths, reports of these extremely rare but potentially serious immune mediated events have also been published in reputed journals," Dr Jayadevan added.
109409851 In 2023, the World Health Organisation said in its report that TTS emerged as a new adverse event following immunisation in individuals vaccinated with COVID-19 non-replicant adenovirus vector-based vaccines.
"TTS is a serious and life-threatening adverse event. WHO has issued this interim emergency guidance to increase awareness about TTS in the context of COVID-19 vaccination and help healthcare providers in the assessment and management of potential TTS cases," the 2023 statement by WHO read.
