Draft explanatory note on the withdrawal of the note for guidance on harmonisation of requirements for influenza Vaccines (CPMP/BWP/214/96) and of the core SmPC/PL for inactivated seasonal influenza vaccines (CMDh/128/2003/Rev5 and CMDh/129/2008/Rev3)
Twice a year, typically in February for the northern hemisphere and in September for the southern hemisphere, World Health Organization experts meet to decide upon the influenza-A and -B-virus strains that should be recommended for use in the production of influenza vaccine for the coming season. For several decades, vaccine manufacturers have been required to conduct small clinical trials with strain-updated seasonal influenza vaccines prior to each flu season and to present the results to competent authorities. Guidance for performing these clinical trials was given in the note for guidance on harmonisation of requirements for influenza vaccines, which has been withdrawn as its content was considered outdated. This explanatory note provides some guidance for the interim period, pending further recommendations from the European Medicines Agency.
