Immunogenicity of Concentrated and Purified Inactivated Avian Influenza Vaccine Formulation
Avian influenza (AI) H9N2 is a low pathogenic virus subtype belonging to Orthomyxoviridae family. Given the prevalence of this subtype as an infectious agent in poultry industry, special attention has been always directed toward the development of vaccine production against this infection. The vaccine of this infection is produced by killing the virus and using a mixture of inactivated antigen ...
متن کاملSafety and immunogenicity of trivalent inactivated influenza vaccine in infants.
BACKGROUND Trivalent inactivated influenza vaccine (TIV) is not licensed for use in infants <6 months old, the group with the highest influenza hospitalization rates among children. METHODS In this prospective, open-label study, 2 doses of TIV were administered to healthy infants aged 10-22 weeks. Adverse reactions were assessed, and hemagglutination inhibition (HAI) antibody titers were dete...
متن کامل1059Expanded immunogenicity of high-dose inactivated influenza vaccine compared to standard-dose inactivated influenza vaccine in older adults
Background. Previous studies have demonstrated the superior immunogenicity of high-dose inactivated influenza vaccine (IIV-HD) in older adults compared to standard-dose inactivated influenza vaccine (IIV-SD), as measured by hemagglutination inhibition (HAI) antibody titers against egg-propagated vaccine antigens. The 20122013 northern hemisphere influenza season was characterized by high H3N2 a...
متن کاملThe efficacy of inactivated oil-emulsion H9N2 avian influenza vaccine
An experimental inactivated oil-emulsion H9N2 avian influenza vaccine was formulated with 3 parts ofinactivated avian influenza antigen A/Chicken/Iran/101/1998(H9N2) emulsified in 7 parts of oil adjuvant.Twelve week-old specific pathogen-free (SPF) chickens were divided into seven groups of 10 birds. Sixgroups were vaccinated with 1, 1/10th, 1/50th, 1/100th, 1/200th and 1/400th field dose of th...
متن کاملEffect of Previous-Year Vaccination on the Efficacy, Immunogenicity, and Safety of High-Dose Inactivated Influenza Vaccine in Older Adults
BACKGROUND High-dose inactivated influenza vaccine (IIV-HD) is an alternative to the standard-dose inactivated influenza vaccine (IIV-SD) in the United States for influenza prevention in older adults. IIV-HD improved efficacy relative to IIV-SD in a randomized controlled trial. Recent observational studies suggest that previous influenza vaccination may influence the immunogenicity and effectiv...
