AstraZeneca has initiated the withdrawal of its Vaxzevria Covid vaccine globally due to a surplus of available updated vaccines and a decline in demand. The company had earlier admitted that its Covid vaccines may cause Thrombosis Thrombocytopenia Syndrome (TTS) in rare cases, but maintained that the vaccine’s safety and efficacy are supported by extensive clinical trial data and real-world evidence. AstraZeneca has also been facing lawsuits related to alleged vaccine side effects, including a class action lawsuit and cases in India over the Covishield vaccine.
