Study shows blood pressure vaccine could be promising.
"A vaccine underway was seen to control morning blood pressure better than the daily medications an early-phase trial presented at the American Heart Association meeting."
The vaccine works by starting an "immune response by binding angiotensin II to a virus-like particle."
In the 72-patient trial, the vaccine "improved daytime systolic blood pressure better than placebo." In addition, when levels of the drug were measured in participants, its "half-life was 123 days, suggesting that the agent could be given three times a year."
Most strokes and myocardial infarcts occur in the morning when blood pressure rises naturally with arousal from sleep." However, "medications are at their lowest concentrations before patients take their morning pills."
