BLOOD PRESSURE VACCINE
ANCHOR LEAD: CONTROLLING BLOOD PRESSURE MAY ONE DAY INVOLVE VACCINES, ELIZABETH TRACEY REPORTS
A vaccine against a blood protein involved in blood pressure regulation helped keep blood pressure under control in a small study reported recently in the Lancet. Rick Lange, a cardiologist at Johns Hopkins, says one good thing about this vaccine is that its effects wear off.
LANGE: The interesting thing about this particular vaccine is it doesn’t last for a long period of time. People got injections at day one, a week later and then they got it three months later. It lasted about three or four months and then it began to wane. The implication is those people would need to be revaccinated. Well, you might ask why would we want to do that? For many individuals they either can’t or they won’t take medication so for those individuals you think if you can give an injection once every three or four months, that may actually be a much better alternative and in the long run may actually be cheaper. :33
Many people with high blood pressure don’t even know they have it and are therefore at risk for heart attack or stroke. I’m Elizabeth Tracey reporting.
