New vaccine kills bird flu

Avian influenza virus researchers say they have been able to get close to a human immunization to fight a pandemic of bird flu.

Experts have long said that there is no way to vaccinate people to fight new virus variants until it evolves. That means that even months and years, epidemics and deaths will continue before a vaccination campaign is launched.

But a group of US researchers at the National Institute of Allergy and Infectious Diseases (NIAID) in Maryland and Emory University of Medicine in Atlanta said they could find a faster treatment.

If they can identify the necessary transformation properties for the variants, the researchers could determine the target for the immune system by marking the virus, the researchers said. This gives them an opportunity to prioritize effective vaccines or other types of antibodies against bird flu.

Types of asexual antibodies are often used to treat cancer. They are indicated in the immune system proteins to attack proteins on tumors. Researchers also do the same on avian influenza viruses. While no one can know if and when the H5N1 virus will attack humans from birds, we need to look for ways to anticipate how that attack will happen. and measures to combat them.

The H5N1 virus is stored mainly in birds' bodies, but researchers are concerned that they can mutate and easily spread to humans and spread throughout the world. According to the World Health Organization, there have been 319 known cases of bird flu, and 192 have died since 2003.

In their attempts to understand the threat, researchers investigated many strains of the H5N1 virus and compared them to the most dangerous flu virus known as the H1N1 virus, which killed between 50,000 and 100,000. people all over the world in 1918 and 1919.

They found that a variant that forms a strain of the H1N1 virus is more contagious to birds, and another is more likely to infect humans . It is in a part of the virus and adheres to the cells in the respiratory apparatus.

The researchers then created a similar variant on the H5N1 virus and vaccinated mice with some of their DNA. Since then, they have discovered an antibody that disables both the H1N1 and H5N1 viruses in birds, and that indicates a bright principle applied to humans to combat the pandemic of bird flu. This vaccine can be made to protect people against viruses with its variants, and is used before the pandemic begins. Asexual antibodies can be used to treat people when they are infected.

Pharmaceutical companies are currently producing vaccines against the H5N1 virus, but they only produce drugs that are resistant to the current H5N1 strain, but the strain is not easily transmitted to humans. Scientists are concerned that they are in a weak fight against new forms of the H5N1 virus that can eventually infect humans.
