LUBBOCK, TX (KCBD) – Right now vaccine manufacturers come up with a new flu shot every year because the virus constantly changes, but soon you may only need one flu vaccine for life.
Researchers at the NIH say they've developed what is actually a two part vaccine that could provide immunity from all strains of the virus. The first shot uses DNA to prime the immune system, the second is a booster shot using the regular flu vaccine formulation.
Experts found mice and ferrets that were vaccinated were protected from several flu strains, dating from 1934. Studies in humans are expected to start soon.
