Immunity to influenza in ferrets. X. Intranasal immunization of ferrets with inactivated influenza A virus vaccines.

abstract：:Individuals with sickle cell anemia are subject to serious infections caused by a number of bacteria, including Salmonella species and Staphylococcus aureus. It has been suggested that in sickle cell anemia, extensive erythrophagocytosis by macrophages may interfere with their antibacterial function and thereby predis...
