Influenza vaccine seeds produced in chicken eggs are selected through HA and NA surface glycoproteins antigenicity, as well as through high replicative ability. Here we characterize the genetic content of recently used thirteen H3N2 influenza vaccine seeds. Interestingly, sequence analysis of the vaccine seeds shows reassortment events leading to PR8:H3N2 segment constellations, ranging from the 6:2 to 2:6 constellations. This study shows that the H3N2 PB1 is the most frequent internal segment incorporated in the tested vaccines seeds.

Seasonal influenza is caused by two influenza A subtype (H1N1 and H3N2) and two influenza B lineage (Victoria and Yamagata) viruses. Of these antigenically distinct viruses, the H3N2 virus was consist...
Influenza vaccine effectiveness (IVE) varies over different influenza seasons and virus (sub)types/lineages. To assess the association between IVE and circulating influenza virus (sub)types/lineages, ...
We evaluated the safety and efficacy of a live attenuated influenza vaccine (LAIV) product in ferrets. The BCHT LAIV product was significantly less virulent than wild-type H1N1 virus, when evaluated b...
Influenza A(H3N2) viruses predominated during the influenza 2016/2017 season and showed extensive genetic diversification. A high vaccination failure rate was noticed during the 2016/17 season in Gree...
In the United States, annual vaccination against seasonal influenza is recommended for all persons aged ≥6 months (1). Each influenza season since 2004-05, CDC has estimated the effectiveness of sea...
The purpose is of this study is to assess the safety and tolerability of three dose levels of H3N2 M2SR influenza vaccine versus placebo delivered intranasally to healthy adult subjects.
The investigators conducted an initial safety and characterisation study in healthy adult volunteers, utilising a unique clinical quarantine facility in London, UK.
This is a Phase II open-label study in approximately 240, and up to 400, healthy males and non-pregnant females, aged 6 months to 17 years. This study is designed to assess the safety, re...
- To assess the tolerability and safety of a single injection of Influenza VLP Vaccine when administered intramuscularly (IM) at 15 µg and 60 µg HA per each strain. - To assess...
Each winter, viruses belonging to two kinds of influenza A ("A/H1N1" & "A/H3N2") and two kinds of influenza B ("B/Yamagata" & "B/Victoria") can cause illness. The yearly influenza vaccine ...
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 3 and neuraminidase 2. The H3N2 subtype was responsible for the Hong Kong flu pandemic of 1968.
Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed or attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The vaccine is usually bivalent or trivalent, containing one or two INFLUENZAVIRUS A strains and one INFLUENZAVIRUS B strain.
A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)
