Why does the United States do not use bird flu vaccine in poultry?

The United States avoided vaccination as Strategies for eliminating bird flu in poultryInstead of relying on an infected sheep With an increased epidemic, the price of the eggs goes up and the height can be changed soon?

And when the flock of millions of sheep die, why is the vaccine not received?

The Department of Agriculture on Friday provides the strongest signal. But the government may change the strategy The agency said that it was conditioned for the H5N2 bird flu vaccine designed to work with the species of the H5N1 virus that flows in the midst of a milk and poultry in the United States. H5N2 belongs to the influenza virus family. H5n1 h5n1 h5n1.

at License to ZOETISVaccine manufacturers in New Jersey are acknowledged that the vaccine has complied with the USDA for safety and “reasonable expectations” of the company’s performance.

However, USDA has stopped allowing extensive quantity distribution. The agency spokesman said in a statement by email that conditions do not mean that the vaccine is approved for commercial use or poultry farmers can be purchased at this time.

“This is just a normal step in the research and development process, not in the process of the vaccine,” said USDA spokesman.

Experts say that the movement shows that the public health officials may consider other tools.– Such as vaccines to continuously fix the crisis In December, the government expanded the country’s milk han.

On Tuesday, there are more than 160 million goose, goose and birds. Disease Control and Prevention Center– There are at least 972 breast outbreaks in 16 states, although the selected livestock is not general practice because they can recover from the disease.

The Bruceroles of Agriculture Secretary expects “in the next few days” to announce a new strategy in the fight against the USDA spokesman, without commenting on whether the vaccine will play a role or not.

If the government has to vaccinate the poultry, it may come with many complications, especially that many trade partners in the United States will not export from countries that allow vaccine Carolona. Bird health experts of Minnesota University said

“When we talk about the poultry, we are talking about ducks and turkey and chickens, and that is the chicken that we eat and the eggs put all the chickens and they are combined in terms of trade limitations,” she said.

The chicken -agricultural industry is responsible for raising chickens, especially for meat consumption. – Probably the most affected. Cardona said. It shows about 96% of the poultry industry. She said and has a large export market. The chicken industry has an economic activity of 449.5 billion dollars and the revenue from the government of 36.7 billion dollars as reported. From the Poultry and Egg Association of the United StatesIndustrial trade groups

“The chicken industry in their own interests will say ‘No vaccines until there is no egg layer, “said Cardona.” It is a violent position. But they can do it. ”

Moreover, the government and manufacturers must have sufficient vaccines to build immunity for poultry throughout the United States. Cardona said that it was burned in 2015. When the bird flu is allowed in the warehouse of the country. In January, USDA said that he would start to build a bird flu vaccine for poultry.

“Therefore, if there is a announcement to us, ready to vaccinate people must order,” she said.

Daniel Perez, a poultry medical expert at Georgia University, the College of Veterinary Science, the study of the influenza virus, jumping from animals to humans. He said that he was worried that the poultry vaccination can help spread quietly

“Sometimes the vaccine may be seen as a double -edged sword,” said Perez. “They can control the disease. But at the same time, they may not be able to control the infection. Therefore, animals that have been vaccinated may not show symptoms of the disease. ”

As agreed with humans that have been vaccinated, not all the birds that have been vaccinated will be protected or protected at the same level as he said.

“If the high route virus enters the place of chicken that has been vaccinated, there may be a low virus simulation, which in the end, promoting the occurrence of the breed by mutation,” Presce said. “And the effect of Those mutations may be an increased virus. The virus host that can be infected with other spirals “including humans

Cardona said it was a “theory”, but it was possible that there may be a vaccine that has “Quiet infection”

However, she noted that the country has many resources to manage that situation rather than ever.

“We have more laboratory and more testing ability than we have returned when there is a theory that is a problem,” Cardona said.

Another thing to consider is that people who are vaccinated, who are likely to be sufficiently protected to make sure they are not infected with the virus. William Schaffner, an expert in infectious diseases from the Vanderbilt University Medical Center in Nashville, Tennessee.

He said that public health experts are concerned about the risks of the health of poultry and milk workers who work close to animals and are often in a dirty environment.

Perez said that there are now continuous research to provide many poultry vaccinations through drinking water.

Another idea is to vaccinate the farmer and the virus as well. Schaffner said.

“Hazmats Suits and Face Shields and Gloves – What works well in the hospital when you take care of patients – do not work well when you go to farm,” he said.

Perez observed that influenza vaccines for poultry and humans are not highly effective and generally use old technology that takes several months to produce quantity.

“I will say that we should use this crisis as an incentive to do more research about vaccines,” he said.
