Scientists Develop Novel Vaccine Concept

Creating vaccines to protect people against **viral diseases like AIDS**, cervical cancer and infectious hepatitis is a delicate balancing act: If the immune system’s response to the vaccine is too strong, toxic side effects can kill the patient. If it’s not strong enough, the virus will spread faster than the immune system can kill it. A **new vaccine** design strategy developed by scientists at The Wistar Institute Vaccine Center could be the answer. The secret is using a herpes simplex **protein called glycoprotein D** to block a specific receptor molecule on antigen-presenting cells, or APCs. These sentinel cells monitor the body for foreign antigens – molecules that can stimulate an **immune response** – from invading viruses.
