"Penn Scientists Pioneer mRNA Vaccine for Bird Flu"

Researchers are developing an mRNA-based vaccine for the H5N1 bird flu virus, which is spreading rapidly among poultry and cattle and has infected two humans in the U.S. The mRNA technology allows for faster vaccine development compared to traditional methods. A study showed the experimental vaccine induced a strong antibody response in animals, providing the same level of protection as traditional vaccines. U.S. officials are considering vaccinating farm workers in close contact with the virus, with 4.8 million doses already prepared from a national stockpile.
