Deadly TB Vaccine?

In a place like South Africa where HIV and Tuberculosis is very prevalent throughout the country, the need and want to find a way to protect and treat those with the virus is high.  But what if my trying to treat one of the problems we are actually increasing the chances of the other becoming lethal?  This could be the case according to scientists who have been studying the effects of the Tuberculosis vaccine on young children in South Africa. The World Health Organization says a
three-year study in South Africa found babies born with HIV had a higher risk of contracting a deadly form of TB if given the widely used BCG vaccine.  The study recommends not vaccinating babies with HIV and delaying vaccination for those babies whose HIV status is unknown”.  With a high rate of both the diseases inside its borders, South Africa is faced with a tough choice, vaccinate the babies and protect them against Tuberculosis or don’t vaccinate the baby so that the risks of HIV don’t increase but leave the babies susceptible for tuberculosis. 
Throughout the course we have learned how HIV is extremely prevalent in many of the countries throughout Africa, especially places like Nigeria.  South Africa could possibly look into finding a different vaccination that would both treat for tuberculosis while not increasing the side effects of HIV.  It is vital that South Africa decides on a solution quick because over the last decade the prevlance rate of HIV infections in the country continue to hover around 30 percent while the rates of Tuberculosis have increased at alraming rates.
