Recurrent Thrombosis in a Lady: Is there a Missed Connection?

Background: COVID19 infection is a recognized risk factor for systemic thrombosis. There have been few case reports about thrombosis following COVID19 vaccination. Case presentation: A middle aged lady presented with acute pulmonary thromboembolism, with history of cerebral sinovenous thrombosis 3 weeks back. Thrombophilia workup and DVT screen was negative, but on reviewing history she had received CoviShield vaccine 1 week prior to the CSVT. Conclusion: COVID19 vaccine use is an under-reported cause for systemic thrombosis. However, larger studies are required to establish the mechanism and causal-effect relationship.
