Findings from a pair of new studies could speed up the development of a universally accurate diagnostic test for human herpes simplex viruses (HSV), according to researchers at Johns Hopkins and Harvard universities and the National Institutes of Health (NIH). The work may also lead to the development of a vaccine that protects against the virus.
Herpes simplex virus infections are an enormous global health problem and there is currently no viable vaccine. For nearly three decades, immunologists’ efforts to develop a herpes vaccine have centered on exploiting a single protein found on the virus’s outer surface that is known to elicit robust production of antibodies. Breaking from this approach, Howard Hughes Medical Institute (HHMI) scientists at Albert Einstein College of Medicine have created a genetic mutant lacking that protein. The result is a powerfully effective vaccine against herpes viruses.
