Post-vaccination embolic and thrombotic events (also termed vaccine-induced prothrombotic immune thrombocytopenia (VIPIT) or vaccine-induced thrombocytopenia and thrombosis (VITT)) are rare types of blood clotting events that have been observed in a very small number of people who had previously received the Oxford–AstraZeneca COVID-19 vaccine (AZD1222) during the COVID-19 pandemic. Both the European Medicines Agency (EMA) on 28 March 2021 and UK's Medicines and Healthcare Products Regulatory Agency (MHRA) on 1 April 2021 have emphasized that the benefits of vaccination using the AstraZeneca vaccine continue to far outweigh any potential risks, noting that there is currently no evidence that the vaccine caused the events, only that it could not be ruled out completely. At a briefing on 7 April 2021, the EMA reconfirmed the benefits of AZD1222 but stated that blood clots are a possible very rare side effect.
Post-vaccination embolic and thrombotic events - Wikipediahttps://www.un.org/sites/un2.un.org/files/coronavirus_vipitguidance.pdfThrombosis with thrombocytopenia syndrome (TTS), also known as Vaccine-induced prothrombotic immune thrombocytopenia (VIPIT), is a rare and new syndrome which has been reported in people who have received COVID-19 AstraZeneca vaccination. The syndrome is characterised by thrombosis (such as central venous sinus thrombosis (CVST) or splanchnic thrombosis), thrombocytopenia and confirmed with a positive PF4-heparin ELISA.
