Genital herpes currently affects up to one in six Americans between the ages of 14 and 49, yet no vaccine or cure for this, common sexually transmitted infection (STI) exists. The first step of this process, or the “prime,” involves a conventional vaccination with weakened HSV-2, which activates HSV-2-specific T cells throughout the body.
In addition to effective protection, the prime and pull immunization also causes little to no inflammation in the genital tract, a problem which had plagued previous vaccine models that fought herpes. In addition to a vaccine against genital herpes, the prime and pull method has many other promising applications. The researchers’ “prime and pull” immunization brings T cells, pictured here in a scanning electron micrograph, to the site of infection, allowing for effective vaccination. Effective vaccines to prevent HSV-2 infection are not yet available, but are currently being developed. HSV-2 Vaccine: Current Status and Insight into Factors for Developing an Efficient Vaccine.
However, a recent paper by Yale professor Akiko Iwasaki and postdoctoral fellow Haina Shin published in Nature reports a promising new vaccine strategy termed “prime and pull” that could easily and effectively protect against the main cause of genital herpes, herpes simplex virus 2 (HSV-2).


T cells have already been shown to play a role in controlling HSV-2 but have limited access to the genital tract, which prevents their entry in the absence of inflammation or infection.
At first, the T cells were expected to attack infected cells in the vaginal lining, but as Iwasaki explains, “our data showed that the protection is really at the level of the neuron.” Specifically, the T cells are hypothesized to prevent virus entry into neurons, where HSV-2 would otherwise remain dormant and cause recurring outbreaks. Of the two serotypes identified, HSV-1 and HSV-2, the former is more common in the United States, but the latter is considered more serious. To facilitate this process, the latest progress in development of these vaccines is reviewed in this paper. If T cells can indeed prevent the virus from getting into the nervous system, Iwasaki adds, the vaccination “can hopefully provide protection for life.”.
In the future, Iwasaki would like to see other researchers use the method both for their own applications and for making the new herpes vaccine clinically available. A summary of the most promising HSV-2 vaccines tested in animals in the last five years is presented, including the main factors, and new ideas for developing an effective vaccine from animal experiments and human clinical trials. According to Medscape, approximately 65% of the United States population is seropositive for HSV-1 by the fourth decade of life. Experimental results indicate that future HSV-2 vaccines may depend on a strategy that targets mucosal immunity.


As well, approximately 25% of the United States population is seropositive for HSV-2 by the fourth decade of life, with women being infected more frequently than men. Furthermore, estradiol, which increases the effectiveness of vaccines, may be considered as an adjuvant. Therefore, this review is expected to provide possible strategies for development of future HSV-2 vaccines. But under a grant from the National Institute of Allergy and Infectious Diseases Division of the National Institutes of Health (NIH), the effort mounted by Vical is directed at developing a plasmid DNA-based vaccine to inhibit recurring lesions in patients latently infected with HSV-2. The vaccine also is intended to reduce viral shedding to help prevent transmission to others. And while still in the preclinical stage, results have shown a reproducible statistically significant reduction in viral lesion occurrence in guinea pigs latently infected with HSV-2.Vical's HSV-2 DNA vaccine program, as seen below, involves collaboration with Lawrence Corey's group at the Fred Hutchinson Research Center.
