Scientists develop effective bird flu vaccine


2015 will go down as a devastating year for the poultry industry, with Avian Influenza (i.e. bird flu) as the culprit. Whether you are a poultry and/or egg farmer, a youth preparing for a 4-H/FFA show, or are just trying to buy eggs at the grocery store – you have probably been affected.

Several states have cancelled their youth poultry shows and exhibitions. This year at our county fair  (in Nebraska) we are looking forward to the alternative poultry projects of an educational showmanship poster contest, poultry art, coops/feeders/waterers, and the rooster crowing contest. The poultry (without the poultry) contest should still be educational and fun.

The USDA’s Animal and Plant Health Inspection Services (APHIS) has reported that more than 48 million birds have been affected by the current avian influenza outbreak which has hit 15 states.

Aviary Systems (2)_UNL photo-finalThe Associated Press (AP) announced Tom Vilsack, U.S. Agriculture Secretary, reported scientists have developed a vaccine strain has tested 100% effective in protecting chickens from the bird flu. Testing is currently underway to see if it also protects turkeys. If it does, the agency plans to quickly license it for widespread production and is seeking funding from the Office of Management and Budget to stockpile it nationally.

“Hopefully we’ll be able to get a lot of folks working collaboratively together and we stockpile enough so that if this does hit and hits us hard we’re in a position to respond quickly,” Vilsack said. “Developing a vaccine targeted to the H5N2 virus that has killed 48 million birds since early March in 15 states, including hardest-hit Iowa, Minnesota, and Nebraska, is one aspect of planning for a potential recurrence of the bird flu,”  says Vilsack.

Scientists believe the virus is spread through the droppings of wild birds migrating north to nesting grounds. They’re concerned it could return this fall when birds fly south for the winter or again next spring. Southern and eastern states including Alabama, Arkansas, and Georgia, states that raise chickens for meat, are worried it could spread there next.

Not all poultry producers are on the same page when it comes to using vaccine to fight an outbreak.

Turkey producers tend to favor vaccination to protect flocks because turkey immune systems appear more vulnerable to viruses. Some egg producers and farmers who raise broilers (chickens produced for meat) often resist vaccination programs because of the possible impact on export markets. U.S. producers export nearly $6 billion worth of poultry and egg products yearly with about $5 billion of that being chicken meat.

“There are many unanswered questions that must be addressed before any strong consideration is given to a vaccination program,” said Tom Super, a spokesman for the National Chicken Council, which represents 95% of U.S. broiler raising chicken farmers. “Two concerns of several are the effectiveness of the vaccine and potential impacts on trade.”

Meetings also have been held with importers of U.S. poultry products to try and convince them not to block all poultry imports if a vaccination program is enacted in response to another outbreak. “That’s still an open question and we’ve been working with a number of countries today to get them convinced to ban regionally as opposed to the entire country,” Vilsack said.

Many countries have a strict policy of refusing to accept meat from nations using a vaccine because it can be difficult to discern through testing whether birds were infected with an active virus or were vaccinated, said James Sumner, president of the USA Poultry & Egg Export Council. Even during the current outbreak which affected 15 states, about 10 trade partners banned poultry imports from the entire U.S., Sumner said.

Vilsack said it’s uncertain when a vaccine would be ready for large-scale production. Even once stockpiled, a vaccination program would not begin until the USDA, consulting with affected states, decided it was necessary to control an outbreak.

  1. I shared this with a 4-H family here. Since Kansas has banned poultry shows this year, they brought posters to the county fair instead of their chickens and turkeys. Thanks for the update.

    1. Thanks Kim. Yea we have come up with several alternatives for our families too. I am excited to see how creative they get with the more static exhibits.
