Some 70 million American adults have high blood pressure.

Three quarters of them rely on medication to keep the condition in check.

But you've got to remember to actually take the daily dose.

Now researchers have devised a longer-lasting alternative,

a vaccine to lower blood pressure, for rats at least.

Scientists jabbed hypertensive rats with three doses of the formulation. It's a DNA vaccine,

containing DNA fragments from angiotensin 2, a hormone that boosts blood pressure, as well as fragments

from hepatitis B to guarantee the immune

system's attention. Cells suck up the vaccine's DNA and start pumping out the proteins the DNA

codes for. When the host defenses get a whiff of the proteins, it reacts. It really revs up against

the hepatitis B fragments, and while it's at it, it starts taking out some angiotensin 2 as well.

The result is a reduction in angiotensin 2's usual blood pressure-raising effects,

similar to what blood pressure meds like Benicar do.

Less angiotensin 2 means more relaxed blood vessels, and a drop in pressure.

That effect lasted six months in the vaccinated rats

and lengthen their lifespan by eight weeks. Necropsy's on the vaccinated rats revealed healthier
