The challenge of achieving vaccines that are both safe and effective has led to two opposing approaches in HSV vaccine development: increasing the efficacy of subunit vaccines (primarily by improving adjuvant formulations), and increasing the safety of live-attenuated vaccines (including the development of "non-invasive" vaccines).
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2), also known by their taxonomic names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans.

The risk of spread between a couple is about 7.5% over a year. [6] HSV is classified into two types, HSV-1 and HSV-2. [1] While historically HSV-2 was more common, genital HSV-1 has become more common in the developed world.

According to a study in Ontario, of people between the ages of 15 and 16, 26.9% of men, 32% of non-pregnant women, and 55% of pregnant women tested positive for HSV-1 antibodies. Between the ages of 40 and 44, 54.7% of men, 88.7% of women, and 69.2% of pregnant women tested positive for HSV-1 antibodies.
Worldwide rates of either HSV-1 and/or HSV-2 are between 60 and 95% in adults. [4] HSV-1 is more common than HSV-2, with rates of both increasing as people age. [4] HSV-1 rates are between 70% and 80% in populations of low socioeconomic status and 40% to 60% in populations of improved socioeconomic status. [4]
Nine herpesvirus types are known to primarily infect humans, [7] at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial and genital herpes), varicella zoster (VZV or HHV-3; the cause ...
