As a pediatrician and translational scientist, I have devoted much of my career to the prevention of viral infections such as herpes. Once a person is infected with either type of HSV, the virus persists in a latent (asleep) form for life -- but periodically awakens to cause recurrent disease. Scientists have pursued the development of a safe and effective vaccine against HSV for decades. Scientists have long assumed that the best antigen for an HSV vaccine is a protein called glycoprotein D (gD).
These results suggested that we needed to adopt a completely different approach to developing an HSV vaccine. We deleted the gD gene from HSV-2 to test the hypothesis that deletion of the virus' dominant protein would result in a different -- and, we hoped, more effective -- type of immune response.
When we tested the vaccine in immuodeficient mice, it proved completely safe: The vaccine caused no signs of disease and no virus was ever detected in nervous tissue--the site where latent HSV lurks. No other HSV vaccine candidate had ever completely prevented HSV viruses from becoming latent. Finally, we transferred antibodies from vaccinated mice to unvaccinated mice, and we found that mice receiving the antibodies were fully protected from subsequent HSV infection.
We are working to optimize models to test whether the vaccine will be effective in reducing recurrences in people already infected with HSV, and we are completing the preclinical work required to test this new vaccine in people.
While there are many more steps to take, we are confident we will learn more about immune responses to HSV and perhaps other pathogens and, hopefully we will be able to take a significant step toward reducing the scourge of HSV.

Dermal fillers are substances that are injected into the skin to overcome the harm done by aging, exposure to sun and from scarring. The herpes virus can infect the cornea area, causing a potentially blinding condition called herpetic stromal keratitis. Their vaccine produced excellent results in preclinical tests, and BenMohamed and Nesburn have found it to also work against genital herpes, which puts people at a significantly higher risk of contracting HIV."Our goal is to attack the virus at the root of the disease," says BenMohamed, a member of UC Irvine's Institute for Immunology.

In infants and those with impaired immune systems, such as transplantation recipients, the viruses can spread throughout the body, resulting in substantial morbidity and mortality.
Vaccines work by exposing the host to viral proteins (referred to as antigens) that stimulate the body to produce antibodies or immune cells that rapidly clear the pathogen before it establishes infection and causes disease. One of the major proteins on the envelope of the virus, gD is required for the virus to enter and spread from cell to cell. We grew this "deletion virus" on cells that expressed HSV-1 gD to allow the vaccine virus to initiate a first round of infection. To test the vaccine's effectiveness, we gave it to mice and then challenged them with high doses of HSV-2 or HSV-1 administered intravaginally or through the skin. The vaccine elicits very high levels of antibodies that recognize a broad array of viral proteins and are rapidly transported into the skin and mucosa to prevent the virus from spreading.

If symptoms occur during the first episode of a genital herpes outbreak, they can be quite severe. The first sign of oral herpes outbreak is usually a tingling sensation in the area of the skin which then turns red. These blisters are filled with clear fluid which eventually burst and they appear soon after the initial symptoms. However, there are availiable anitiviral medications to minimize the severity, frequency, and frequency of outbreaks.
Some dermal fillers are used superficially to smoothen out shallow lines and wrinkles while others are injected deep into the skin to fill out deeper lines and creases.
While it often remains dormant, the virus can be activated by psychological, chemical or environmental stresses and infect the eye's corneal region, sometimes causing a potentially blinding condition called herpetic stromal keratitis.Current drug therapies can treat ocular herpes but do not prevent future attacks. Activation comprises active transcription of viral RNA and high lytic protein expression accompanied by low LAT production. To address this issue, a two-vaccine schedule for measles (15 months and four to six years of age) is recommended. However, over a period of time, the recurrence of herpes outbreaks decreases in frequency.
Symptoms of an initial herpes outbreak generally occur within two weeks after infection, and are usually more severe than subsequent recurrences. I have treated infants and children with herpes encephalitis or disseminated disease and seen the devastation firsthand, fueling my passion to help develop a vaccine to prevent HSV.


Several vaccines containing gD alone or combined with another viral antigen have been advanced into the clinic, but have had disappointing results so far. The mice were completely protected from infection, and, again, no latent virus could be detected in nervous tissue. We are now studying why deletion of the gD gene caused this different and more protective type of antibody response. Blisters pop themselves and will look like sores, but will crust up to disappear with time.
There is no doubt that at some point herpes sores resemble pimples but usually it is very difficult to make that mistake. If this is your first outbreak, you may experience pain while urinating or difficulty in emptying your bladder, swollen lymph nodes in the groin, and mild to severe itching where the outbreak is about to occur. Antiviral medications are proven to stimulate the immune system and slow down the replication rate of the virus. Dermal fillers are used in areas where the natural fat of the body has atrophied leaving wrinkles and sunken areas.
All the participants were asked to provide blood samples and swabs of their eyes and mouth for 30 consecutive days. The most recent vaccine to be evaluated induced high levels of antibodies directed against gD, but still failed to protect men and women from HSV-2 infection when tested in large clinical studies.
Therefore, it would not be able to spread further but would allow the immune system to recognize the viral proteins. The fluid filled blisters eventually break and fluid that comes out of the blisters is full of millions of herpes virus cells making this the most contagious phase. Aciclovir (Zovirax), Famciclovir ( Famvir), and Penciclovir are examples of presciption antiviral medications avaliable in the market. Anthony Nesburn with the Gavin Herbert Eye Institute, UC Irvine's ophthalmology department, have developed a promising vaccine to give long-term protection from HSV-1 activating and attacking the cornea. In addition, both types are leading causes of encephalitis (infection of the brain), which can result in devastating disease in newborns who are infected during delivery, and are also major causes of sporadic encephalitis in children and adults. The two men recently formed a company, Micro Antigen Technologies, to create a version of the vaccine for early-stage clinical trials on human patients."Developing a vaccine consumes time and resources, but we've been fortunate to have the support to make it this far," BenMohamed says. Illness is manifested by a prodrome of three days with systemic toxicity, prostration, high fever, coryza, headache, photophobia, dry hacking cough, and impressive conjunctivitis. Koplik’s spots, the pathognomonic enanthem of measles, appear on the buccal mucosa opposite the molars during the prodromal period and fade within three days after the onset of the rash.
It’s real danger lies in severe fetal infection that can develop if infection occurs during early pregnancy. In the first few weeks of pregnancy, the chance of transmission is 30 to 50%; at five to eight weeks, it is 25%, and from nine to 12 weeks, the risk is 8%.
The prodrome consists of malaise, cough, sore throat, low grade fever, headache, and a pink maculopapular rash that begins on the face with caudal progression. Other clinical findings include suboccipital and postauricular adenopathy and arthralgia (in 25% of affected patients).
Unlike measles, where systemic toxicity and fever are the rule, fever is less common in rubella.Erythema Infectiosum (Fifths Disease)Erythema infectiosum is a mildly contagious disease caused by human parvovirus B19.
It typically affects school aged children (5 to 15 years of age).53-61 The incubation period is usually one to two weeks with a prodrome consisting of low grade fever, malaise, and headache. A fiery red macular rash soon appears on the cheeks (“slapped cheek”), lasts one to four days, and is followed by a more generalized rash which evolves into a distinctive, lacy, reticular pattern most prominent on the extensor surfaces of the extremities. Children with erythema infectiosum typically feel well but constitutional symptoms, such as headache, fever, sore throat, and coryza, occur in 5 to 15% of patients. Lastly, this infection is associated with transient aplastic crisis63,68 in patients with hemolytic anemias, hemoglobinopathies (particularly sickle cell disease),69 or idiopathic thrombocytopenic purpura,57,62,70 as well as intrauterine infection and fetal death71 (risk ranges from 3 to 10%) in pregnant women infected during the first 20 weeks of gestation. Yoto et al72 reported epidemiological evidence suggesting that parvovirus B19 may be the cause of acute hepatitis. It should be noted that, when children have the rash of fifth’s disease, they are no longer infectious.Roseola27,48,49Roseola is caused by human herpes virus 6 (the other five human herpes viruses, herpes simplex 1 and 2, varicella-zoster, cytomegalovirus, and Epstein-Barr virus are also known causes of skin eruptions). Virtually all cases occur between six months and three years of age, with most cases occurring before age one.
The incubation period is one to two weeks and the illness classically presents with a fever of up to five days followed by precipitous defervescence and the appearance of a pink maculopapular rash on the neck and trunk.
Despite the elevated temperature, affected children are brighteyed and do not appear to be acutely ill. Periorbital edema, when present in a febrile otherwise non-toxic child, is a useful clue during the pre-exanthematous stage. A common complication (seen in approximately 6% of cases) is febrile seizures.Varicella48,49,73,74Varicella is a common and highly contagious systemic illness caused by the varicella-zoster virus.
Half of the cases occur before age five and 90% by 15 years, with peak incidence in late winter and spring. After an incubation period of two to three weeks, the illness begins with a low grade fever and malaise.


The characteristic skin eruption begins as red macules that progress to discrete vesicles surrounded by erythema. The eruption typically begins on the face and trunk and spreads in successive crops centrifugally to the extremities over a week long period. The presence of lesions in varying stages of evolution and minimal distal extremity involvement helps to differentiate chickenpox from smallpox. Severe presentations of varicella may occur in children receiving steroids and immunocompromised patients.
The Tzanck smear can demonstrate multinucleated giant cells and, in questionable cases, can be used to confirm the diagnosis. In most cases, management of varicella is directed at symptomatic relief of constitutional symptoms and ameliorating pruritis.
Secondary bacterial infections, if present, should be treated with antibiotics directed against Staphylococcus aureus.
Acyclovir may be effective in treating varicella and has been shown to prevent visceral dissemination in immunocompromised children. Results were less supportive with respect to the number of days to the relief of itching, and there was no clinically important difference between acyclovir and placebo with respect to complications associated with chickenpox. In summary, the clinical importance of acyclovir treatment in otherwise healthy children remains uncertain. Children with a history of chickenpox in the first year of life have a much higher incidence of zoster (shingles) in childhood (relative risk 2.8).
The calculated incidence rate of zoster by 12 years of age in children who acquired varicella by one year of age in the Rochester study was 4.1 cases per 1000. Herpes SimplexThe most common presentation of primary herpes simplex in children (one to five years of age) is herpetic gingivostomatitis (HSV-1), but infection may also involve the eye (herpetic keratoconjunctivitis), the external genitalia (HSV-2), and fingers (herpetic whitlow).
It should be noted, however, that oral HSV-2 and genital HSV-1 infections have become increasingly more common.
Wrestlers are prone to spread herpes infection to one another, a condition called herpes gladiatorum.Treatment76-77 is usually symptomatic, though acyclovir may be prescribed to shorten the course of more severe or recurrent disease. Recurrent HSV presents as grouped vesicles near the site of primary infection, and are often preceded by a burning or tingling sensation in the affected area. Triggering mechanisms responsible for reactivation include febrile illness, menses, stress, sunburn, or local trauma. Recurrent infection differs from primary infection in the smaller size of vesicles, their close grouping, and the usual absence of constitutional symptoms. Neonatal herpes usually develops when infants are delivered vaginally to mothers who have genital herpes.
About half of these infected infants will have skin manifestations, and half of these, if untreated, will either die or suffer serious neurologic or ocular sequelae. Again, the Tzanck smear can demonstrate multinucleated giant cells and, in questionable cases, can be used to confirm diagnosis. Children who received acyclovir had oral lesions for a shorter period of time verses placebo (four vs. This group of viruses was previously divided into coxsackie, echo, and polioviruses, but has now been unified within the picornavirus family. The age of the child at the time of infection appears to be significant in disease expression; exanthems are more common in younger children, whereas aseptic meningitis is more prominent in older children.
The cutaneous manifestation is typically morbiliform, though vesicular and urticarial rashes have been reported.
Common complications include pericarditis, myocarditis, pleurodynia, parotitis, hepatitis, pancreatitis, and encephalitis. Hand-foot-mouth disease, also caused by enteroviruses (most commonly coxsackie A16), is manifested by malaise and fever with oral vesicles (severe odynophagia with associated anorexia), followed by vesicles on the hands and feet.
The diaper area may be affected in infants.Epstein-Barr InfectionsIn young children, an exanthem is seen in as many as one-third of infected patients. After an incubation period of one to two months, acute infection begins insidiously with a high fever, congestion, odynophagia, adenopathy, and hepatosplenomegaly. The mono-spot test is unreliable in children younger than four years of age and if symptoms have been present for less than five days. Acute and convalescent EB viral titers and the finding of atypical lymphocytosis (seen in 70%) are supportive.
It is purported that up to a quarter of children with EBV may have concurrent beta-hemolytic streptococcal infection.
