Promising Results for NIH Dengue Vaccine

On January 23, the NIH announced that a Phase I clinical trial for a dengue vaccine candidate has yielded promising results. Dengue is a potentially lethal virus which causes severe fever, headaches, and rashes. WHO estimates that 50 to 100 million cases of dengue occur worldwide each year, including here in the U.S., and has recently warned of the possibility of a global dengue epidemic.

The results of the trial, in which 90% of participants developed some immunity to the virus, represent a significant breakthrough in the development of a safe and effective dengue vaccine. The vaccine costs just $1 to produce, making it cost effective and ideal for future distribution to developing countries. The vaccine will enter Phase II clinical trials shortly and is yet another example of the importance of federal funding to advance global health research.
