This article in technologynetworks.com (which is new to me) says a universal flu vaccine could be here within five years.

Researchers reported that six of 11 nonhuman primates inoculated against the virus that circulated a century ago — the 1918 flu — survived exposure to one of the deadliest viruses in the world today, H5N1. In contrast, a control group of six unvaccinated nonhuman primates exposed to the H5N1 virus succumbed to the disease.

Sacha said he believes the platform “absolutely” could be useful against other mutating viruses, including SARS-CoV-2…

This approach harnesses a vaccine platform previously developed by scientists at OHSU to fight HIV and tuberculosis, and, in fact, is already being used in a clinical trial against HIV.

I feel sorry for the 11 monkeys (chimps?) who gave their lives for this research. But getting rid of flu, Covid, HIV and tuberculosis certainly sounds pretty good. I’m a little confused about why H5N1 is so lethal in these monkeys – is this the same virus causing mild symptoms and no deaths (so far) in cows and a few humans?
