LONDON: British scientists have developed a vaccine which they claim will help people suffering from hypertension to control their blood pressure.
The vaccine developed by Cheshire-based drug firm Protherics has been successfully tested and is expected in the markets within five years.
The vaccine uses a protein found in limpets, a sea creature, to attack a hormone called angiotensin produced by the liver. Angiotensin raises blood pressure by narrowing arteries. The vaccine, however, turns the body’s immune system against the hormone.
It would need a course of just three jabs, with a booster every six months.
A booster shot every six months, or even once a year, would keep blood pressure low, the researchers said.
People who have tried it have suffered a few side effects, although one in ten did complain of a brief flu-like illness.
Protherics is planning trials of an improved version of the vaccine, which is ten times more effective at stimulating the immune system than its original formula, the Daily Mail reported.
“Improving compliance in this way could save thousands from life-threatening complications such as heart attack or stroke,” said Andrew Heath, an official of Protherics.
High blood pressure which affects a third of all adults doubles the risk of dying from heart disease or stroke and is blamed for 60,000 deaths a year in Britain. It is currently treated with pills with side effects and some patients simply stop taking them.
The Swiss firm Cytos Biotechnology is also developing a similar vaccine that uses an empty virus shell to spur the immune system into action.
Many people turn to supplements to combat the persistent tiredness and flu like symptoms that characterize this poorly understood and disabling disorder. Although no one knows its cause, a weakened immune system may be a factor.
Continuing or recurring fatigue lasting at least six months and not relieved by sleep or rest.
Memory loss, inability to concentrate, headaches.
Low-grade fever, muscle or joint aches, sore throat, or swollen lymph nodes in neck or armpits.
When to Call Your Doctor Fatigue that lasts longer than two weeks or is accompanied by sudden weight loss, muscle weakness, or other unusual symptoms may signal other, more serious ailments.
Fatigue can be a side effect of certain medications. Your doctor can rule out other possible and often correctable causes.
Have your doctor monitor your progress even if you are improving or if fatigue worsens despite home treatment. Reminder: If you have a medical condition, talk to your doctor before taking supplements.
What It Is
Marked by profound and persistent exhaustion, chronic fatigue syndrome (CFS) affects more women than men, most younger than age 50. Patients feel weak and listless much of the time and often have difficulty sleeping, concentrating, and performing daily tasks; many also have underlying depression. Doctors disagree about whether CFS is a specific condition or a group of unrelated symptoms not attributable to a single cause.
What Causes It
The specific cause of CFS is unknown, but an impaired immune response may play a role in its onset. People with CFS have other immune disturbances as well: About 65% are allergy sufferers (versus only 20% in the general population), and some have autoimmune disorders such as lupus, in which the immune system attacks the body’s own healthy tissues.

How Supplements Can Help
Supplement therapy aims to restore a healthy immune system, so begin with vitamin C and carotenoids. A powerful immune enhancer, echinacea can be added to the mix; it can be alternated with the herbs astragalus, which has antiviral and immunity-enhancing effects, pau d’arco, which fights many microbes (especially the yeast infections so common in those with low immunity), or goldenseal. For muscle pain, use magnesium too.
What Else You Can Do
Try behavioral counseling and relaxation techniques, such as hypnosis or meditation, to manage stress and treat any underlying depression.
Get a good night’s sleep. If needed, use supplements for insomnia, such as valerian, melatonin, or 5-HTP.
Mild aerobic exercise may be excellent for chronic fatigue syndrome, according to a recent study in the British Medical Journal. After a 12-week program of walking, swimming, or biking from 5 to 30 minutes a day, 55% of CFS patients felt “much” or very much better. Relaxation and stretching exercises may also work. But start and proceed slowly: If you do too much, you may suffer a setback. It may help to keep an energy diary-to record peaks and ebbs of energy-and plan your schedule around the times you routinely feel the best.
