History of antiplatelet, anticoagulant therapy or those who are currently ongoing this therapy can take this vaccine because these are not contraindications for receiving the vaccine. But it is important to follow up with your doctor for a risk-benefit assessment based on clinical judgement before you take the vaccine. As covishield is given through the intramuscular route, so this vaccine should be given with caution in people who have low platelet count( also called thrombocytopenia), any coagulation disorders, or those who are on anticoagulation therapy as bleeding or bruising may occur after the administration of this vaccine in these persons.
