Despite of existence of an effective vaccine, chronic hepatitis B virus (HBV) infection is still a global public health problem with at least 370 million virus carriers, who are of a high risk of cirrhosis and hepatocellular carcinoma development. Call your doctor for medical advice about side effects. Rosenthal, PhD, tells WebMD that the information being gleaned about viral infection and protection may eventually lead to effective prevention and treatment for diseases from malaria to cancer. The first question to come to mind is that the article states that trial is for Herpes Simplex Virus 2 which is responsible for causing genital herpes. There has been proof of concept with regard to a herpesvirus vaccine; chicken pox and shingles both have very effective vaccines to protect against the infection and emergence of varicella zoster virus. Once the compound is gone, the virus can no longer replicate, but the body now has the antibodies to defend against future HIV exposure. As soon as you come in contact with poison ivy, you should immediately apply some lemon juice over the affected area.
We have recently extended our efforts to cure HSV infections by developing DNA editing enzymes as potential HSV treatments. People may also suffer from this disease if they have any of the family members suffering from it. 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. This showed that ADCC protected against HSV-2. The replication competent live virus vaccine approach has the advantages of stimulating a broad immune response (antibody, CD4+ T cells, and CD8+ T cells) and presenting all epitopes from the entire genome to generate multiimmune responses. Other strategies, including genetically attenuated mutants and vectors, are in preclinical development. An effective vaccine against the virus that causes genital herpes has evaded researchers for decades.
Belshe reported financial links with Vivaldi Biosciences, GlaxoSmithKline, MedImmune, and Merck. The findings help explain the results of the Simplirix™ trial. An alternative is artesunate, which is available from CDC as an investigational new drug protocol (532).
