Regarding vaccination, much has been learnt in Mexico. The most important is the following:a) The best vaccination strategy is to use a Prime Boost Strategy (Prime with a live vectored vaccine at day of age, most widely used in Mexico is using a Pox vectored vaccine and boost with a killed vaccine applied at the farm at 10-12 days of age to decrease the neutralization of MABs from progeny coming f ...

FindingsAvian influenza virus (AIV) is a member of the Orthomyxoviridae family, Influenzavirus A genus. AIV is characterized by its ability to undergo constant antigenic changes [1]. AIV envelope contains two major glycoproteins, hemagglutinin (HA) and neuraminidase (NA) [2]. The HA/NA proteins play a key role during cellular infection. Different HA/NA combinations allow AIV subtype discrimination ...

BackgroundAvian Influenza (AI) virus belongs to the Orthomyxoviridae family, Influenzavirus A genus. This virus possesses eight segments of single-stranded RNA genome. Two of these segments encode for two important membrane glycoproteins, hemagglutinin (HA) and neuraminidase (NA) [1], that play a key role during cellular infection. These two proteins are used for virus subtype classification ...

I agree with Dr. Avner Figner, updating of the vaccine strain si very important in terms of protection, specially in killed vaccines. In Mexico this is done once a year.

Mexican experience indeed indicates that MDA play an important role in seroconversión of vaccinated birds, specially if intended to be vaccinated at day old. This is the reason they have to be vaccinated in the farm between 10-14 days in current vaccination programs. Vaccinated at day of age gives por seroconversión and protection if MDA are high.

The A (H1N1) pdm09 influenza pandemic and, most recently, the A(H3N2) variant outbreak in several areas of the USA are examples of swine influenza viruses infecting humans. These cases highlight the need for reliable and rapid diagnostic tests to elucidate the epidemiology and evolution of swine influenza viruses (Smith and others 2009, Centers for Disease Control and Prevention 2012a, b, c). Curr ...

Responding to your comments and inquieries, we have worked in a collaborative proyect with the USDA team to construct 3 recombinant vaccines that belong to genotypes VI, VII and XIII. The strain to be used will depend on the population of velogenic field strains circulating in each country. We have both the live and killed vaccines developed. The vaccine will be available through asignated distrib ...
