Scientists Near Breakthrough with Potential 'One-and-Done' Universal Flu Vaccine

A new vaccine platform showing promise in animal trials could eliminate the need for annual flu shots within five years.

The vaccine targets stable internal proteins of the flu virus, offering broad protection against multiple strains.
Developed using cytomegalovirus (CMV) as a vector, the vaccine has successfully protected monkeys from H5N1 bird flu.
Researchers believe the vaccine could also be effective against other mutating viruses, including COVID-19.
The approach has already shown promise in clinical trials for HIV and certain cancers.
Funded by the Bill & Melinda Gates Foundation and the NIH, the vaccine could revolutionize infectious disease prevention.
