How does herpes vaccine work?

Herpes is a virus that can cause painful blisters and ulcers. There are several types of herpes and all types can be spread from one person to another. The Herpes Simplex virus causes both oral and genital herpes and the Herpes virus zoster causes chicken smallpox and shingle. There is no cure for herpes, and although drugs can alleviate the symptoms of recurring infections caused by this virus, until recently there was no way to prevent the spread of the virus if it was made with someone infected. However, scientists are developing a vaccine against herpes to prevent herpes from spreading. The genital herpes, which is caused by herpes simplex virus, affects approximately 55 million Americans and an effective vaccine for this type is particularly high. In order to understand how the Herpes vaccine works, it must first understand how Herpes pre -defense mechanisms of the body.

first Herpes Simplex infects the cell. MeltThe cell sends a signal to alert other cells of imminent danger. The cells that receive the signal then return to the antiviral state as a means of protection, and basically create a shield to bounce damage. Herpes, however, produces a protein called ICPO, which is complex and causes infected cells to destroy their own shields. This allows the Herpes virus to take over, multiply, then skip into new cells and also deceive them. This is followed by a mass chaos and the Herpes virus finds a home in a large group of cells.

So, to alleviate the effects of this deceptive invasion, scientists create a vaccine against herpes that removes genetic instructions for the production of ICPO protein. Without these instructions, the virus has no ICPO with which it could deceive cells, although the rest of the virus remains intact, it is prevented and unable to cause harm. In this way, the weakening of the virus creates what is called the "attenuated" virus. Other vaccines that use this approach are measles, mumps, rubella, palsy andYellow fever.

Herpes zoster also has a vaccine. This Herpes vaccine is served to avoid both shingles and chickenpox. Although it is slightly different from the vaccine in the works for Herpes Simplex, the Voster vaccine also works by injecting the weakened version of the virus. The shingles vaccine and the chickenpox vaccine contain a strain of weakened Varicella zoster virus.
