Strike a Y
Strike a Y in support of access to healthcare for PID patients
The Y pose refers to the shape of an antibody, but it also symbolises the community – just like the World PI Week logo!
Show your solidarity during World PI Week: from 22-29 April, post a picture on Facebook, Twitter or Instagram with #PIctureAwareness, striking a “Y”!
In 2022, we are striking a Y in support of access to healthcare for PID patients.
