Scientists have created a miracle nasal spray vaccine that can prevent heart attack.

Scientists from the Lund University in Sweden have created a nasal spray vaccine that reduces fat in the arteries and thereby prevent heart attacks. The vaccine is expected to hit the markets by the next five years.

The vaccine works by stimulating the body's immune system to produce antibodies which tackle the build-up of fatty deposits in arteries called plaque, according to a Mirror report.

Experiments conducted on mice with fat in the arteries revealed a 60 to 70 percent reduction of plaque in its arteries. Studies were conducted with some dose of vaccine everyday.

According to the scientists, this new treatment will help cardiac patients to get rid of excess fat in their arteries, which is considered very safe compared to other heart treatments. Researchers believe that a good number of patients are likely to benefit from this treatment.

"The antibody therapy is likely to be expensive so you could probably only afford to give it to people at high risk rather than everyone," Mirror quoted Jan Nilsson, professor at the Lund University, as saying.

"There will be great interest in the outcome of the on-going studies to see firstly if this approach is safe and secondly, whether it can influence the progression of vascular disease in the long term," said Peter Weissberg, Medical Director at the British Heart Foundation.

"It is very promising, but it will take some time before we know if it is successful and, if so, which patients are likely to benefit most from this treatmen," Weissberg added.
