Australian scientists have developed a new vaccine for tuberculosis (TB) with the new hope to prevent the spread of the disease. Researchers with Sydney’s Royal Prince Alfred Hospital have developed the vaccine which they said are more effective than the current treatment. The current TB vaccine, known as BCG, is given to newborn babies in countries with a high rate of the disease. But it has not stopped the disease spreading to more than 2 billion people. Australian Broadcasting Corporation radio quoted researcher Warwich Britton as saying on Friday that BCG “only works for about10 years and therefore folk can develop tuberculosis later in lifeand that causes the spread of the disease. The research team led by Britton has hoped that the new vaccine will last 20 years. The new vaccine has been sent to the United States for testing on guinea pigs with the aim of setting up human trials within fiveyears.
