Korea health agency lets Sanofi cut NIP flu supply, igniting favoritism furor
Sanofi-Aventis Korea reduced its National Immunization Program (NIP) flu vaccine supply from 2.25M to 1.75M doses due to production disruptions. The Korea Disease Control and Prevention Agency amended the contract without penalties, allowing Sanofi to divert 500,000 doses to the higher-priced private market. Critics argue this favors Sanofi and may disrupt supply for domestic firms like GCGC Biopharma (006280).
