B Positive: Immune Cell-ebrating Immunity

Every day, we encounter tens of thousands of microbes. Our antibodies are our anti-buddies, protecting us from infection.

The Day of Immunology is the perfect day to immune cell-ebrate this biology that keeps us alive. We also celebrate a literally life-saving change to blood donation eligibility rules. Gay and bisexual men, trans people, and other previously excluded communities can now donate blood.

This week, we’re exploring blood types, blood donation, and the incredible B cells that make antibodies. We’ll talk about why you can’t receive just any blood type, and how vaccines train your B cells to protect you.

B cell immunologist Dr Liam Kealy from Monash University is here to help us understand the microscopic heroes that circulate through our bodies, protecting us every single day. So let’s circulate some knowledge about immunity!
