GPs are being advised to refer patients with suspected anaphylactic reaction to influenza vaccine to an allergist after research found almost nine in 10 are being misclassified as allergic to the injection.

The high number of wrong classifications was likely because it was difficult to distinguish between true anaphylaxis and a plethora of immunisation stress-related responses, said lead researcher Dr Beau Carr, from Monash Health in Melbourne.
