Since its first product was launched in 2017, there has been no product recall for OLYMVAX. In addition, the Company has prepared the Procedure for Product Recall Management and regularly evaluates the effectiveness of the recall process by means of simulated recalls, and the results of the simulated recall evaluation show that the existing recall process is effective and feasible.

The Company will continue to strictly control quality and provide safe, high-quality and effective vaccines for vaccinators!
