Abstract
Routine immunization against virus influenza is not recommended at this time because of the appearance of new strains not included in present-day vaccines. As more strains of the virus are included in this vaccine, its efficiency is being improved. Vaccination of adults and children is discussed. Final judgment must await further laboratory and clinical investigation.Entities:
