But the long-term EAIRs of nasopharyngitis (15.07/100PYs with IL-17 inhibitors; 10.75/100PYs with IL-23 inhibitors) and upper respiratory tract infection (8.52/100PYs with IL-17 inhibitors; 5.84/100PYs with IL-23 inhibitors) were somewhat high. Here, IL17A is linked to Recurrent upper respiratory tract infections.
