syringe

A medical syringe, used to inject a vaccine or draw blood. Typically depicted at a 45° angle, with the needle at the top right. Commonly used for content about health, medicine, and related professions, as well as various references to needles, medications, tattoos, blood, or, more recently, the coronavirus vaccination. Originally used to represent a blood donation, and showing blood inside a bucket. In 2021, many platforms have switched to a more generic empty syringe. Google and Facebook's designs previously featured green liquid.
