Vaccine that lowers cholesterol could prevent heart disease

20/06/2017

A vaccine that helps lower cholesterol will now be trialled on humans following successful studies in mice. Researchers from the Medical University of Vienna will now test the safety of their experimental treatment – which stops fatty deposits clogging the arteries – on 72 volunteers. If the trials are successful, the vaccine would offer an alternative for people who currently take pills on a daily basis to reduce their risk of angina, stroke and heart attack. Writing about their cholesterol-lowering vaccine in the European Heart Journal, Dr Guenther Staffler and colleagues from The Netherlands Organisation of Applied Scientific Research say it will take many more years of tests before it is known whether the treatment is safe and effective in humans. In studies of mice, the treatment cut low density lipoprotein (LDL) cholesterol (bad cholesterol) by as much as 50% over 12 months and appeared to stop the build-up of fatty deposits in the arteries. Regardless of whether the vaccine becomes available in the future, the researchers were keen to stress that it should not be seen as an excuse for people to avoid exercise and eat lots of high-fat food. Nevertheless, the treatment could be useful for individuals who have high cholesterol due to an inherited condition called familial hypercholesterolaemia.
