UNAIDS Commends Commitment By The Bill & Melinda Gates Foundation To Advancing Vaccine Research And Development UNAIDS strongly applauds today's announcement by the Bill & Melinda Gates Foundation to invest USD 10 billion into research and development of vaccines over the next 10 years. The announcement, made at the World Economic Forum in Davos, is a welcome step forward in commitment to vaccine research, however large gaps in funding for the research and development of vaccines still remain... 31 January 2010

Immune Memory Formation Seen In Early Stages Of Viral Infection In an acute viral infection, most of the white blood cells known as T cells differentiate into cells that fight the virus and die off in the process. But a few of these "effector" T cells survive and become memory T cells, ensuring that the immune system can respond faster and stronger the next time around... 30 January 2010

Higher viral load during early pregnancy, poor adherence, associated with increased risk of HIV infection for infants A higher viral load during the earlier stages of pregnancy is an important risk factor for mother-to-child transmission of HIV, even when a woman’s viral load is below 500 copies/ml at the time of delivery, French investigators report in the February 15th edition of Clinical Infectious Diseases. 09 February 2010

HIV treatment responses in everyday care matching clinical trial levels Patients receiving routine HIV care through a large US hospital had treatment responses that matched responses rates seen in recent clinical trials, indicating that very high rates of undetectable viral load are achievable in everyday clinical care, US investigators report in the February 15th edition of Clinical Infectious Diseases. 09 February 2010

Less resistance with FTC than 3TC when combined with tenofovir Amongst patients experiencing a rebound in viral load, those taking 3TC (lamivudine, Epivir) in combination with tenofovir (Viread) were more likely than those taking FTC (emtricitabine, Emtriva) and tenofovir to develop a number of key resistance mutations. 08 February 2010
