The U. S. government recently pulled the plug on a major project. The project was to create a vaccine for bird flu. This vaccine was to protect people from flu viruses that could start a pandemic. The government was worried about the safety of the mRNA technology used in the vaccine.

The Department of Health and Human Services ended a $766 million deal with Moderna. Moderna is a company working on an mRNA vaccine for flu strains that could cause pandemics. This includes the H5N1 bird flu virus, which has been making people nervous.

The government said it stopped the project after a careful review. They felt that continuing to invest in Moderna's H5N1 mRNA vaccine was not the right move. They cited scientific and ethical reasons for their decision. They also mentioned concerns about the safety of mRNA technology.

The government wants to focus on vaccine platforms with better safety records. They also want transparent data practices. This shift in focus is part of their plan for pandemic preparedness.

One expert, Jennifer Nuzzo from Brown University's Pandemic Center, was not happy with the decision. She said it was disappointing but not surprising. She pointed out that other methods of making flu vaccines exist. However, these methods are slower and can rely on eggs, which might be scarce. She also noted that there are only a few companies making flu vaccines. This means there might not be enough vaccines for everyone during a pandemic.

The cancellation happened even though Moderna had positive results from a study. The study involved 300 healthy adults and showed a strong immune response and good safety profile. Moderna plans to find other ways to move forward with the program.

Experts outside the government criticized the decision. They said it puts the health of Americans at risk. They pointed out that bird flu is a known threat. If the virus starts spreading from person to person, many people could get sick or die.

The H5N1 flu virus has spread to many dairy herds and poultry farms. It has caused 70 human cases. While it has had a high death rate in other countries, it has only caused one death in the U. S. So far, it has not shown signs of spreading easily from person to person. However, experts are worried that the more the virus spreads, the greater the chance it could mutate and become more dangerous.
