BACKGROUND Acute asthmatic exacerbation and readmission may be associated with severe influenza infection and asthmatic children are a priority group for influenza vaccination. To date, our study is the first to evaluate the outcome of the influenza vaccine in asthmatic Asian children. OBJECTIVE To analyze the outcomes of inactivated influenza vaccine in children with mild persistent asthma ...

influenza is a contagious viral disease that is seen in avian, human and other mammals, so its control is important. vaccination against influenza virus subtype h9n2 is one of the ways in controlling program, for this reason several vaccines has been produced. recently, application of inactivated oil-emulsion vaccines in poultry for controlling low pathogenic avian influenza is increasing. at p...

Influenza A virus is a negative-strand segmented RNA virus in which antigenically distinct viral subtypes are defined by the hemagglutinin (HA) and neuraminidase (NA) major viral surface proteins. An ideal inactivated vaccine for influenza A virus would induce not only highly robust strain-specific humoral and T-cell immune responses but also cross-protective immunity in which an immune respons...

METHODS: In this randomized study, we assigned 340 mothers to receive either inactivated influenza vaccine (influenza-vaccine group) or the 23-valent pneumococcal polysaccharide vaccine (control group). Mothers were interviewed weekly to assess illnesses until 24 weeks after birth. Subjects with febrile respiratory illness were assessed clinically, and ill infants were tested for influenza anti...

H2N2 influenza virus caused a pandemic starting in 1957 but has not been detected in humans since 1968. Thus, most people are immunologically naive to viruses of the H2 subtype. In contrast, H2 influenza viruses are continually isolated from wild birds, and H2N3 viruses were isolated from pigs in 2006. H2 influenza viruses could cause a pandemic if re-introduced into humans. In the present stud...

Seasonal influenza continues to have a huge annual impact in the United States, accounting for tens of millions of illnesses, hundreds of thousands of excess hospitalizations, and tens of thousands of excess deaths. Vaccination remains the mainstay for the prevention of influenza. In the United States, 2 types of influenza vaccine are currently licensed: trivalent inactivated influenza vaccine ...

An analysis of the main advantages and shortcomings of the existing inactivated and live vaccines against the equine influenza viruses (EIVs) is given in this paper. For the first time, the most important information, concerning the development of a new live modified cold-adapted (ca) equine influenza virus vaccine based on the A/HK/Otar/6:2/2010 strain is summarized. We discuss a number of uni...

A collection of Practice Guidelines published in AFP is available at http:// www.aafp.org/afp/ practguide. The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) has released its yearly recommendations for routine influenza vaccination in the 2015-2016 season. Updates this year include the antigenic composition of seasonal influenza vaccines availab...
