Shingles is a viral disease characterized by a skin rash consisting of painful blisters that usually appear in a strip across a person’s face or body. While the symptoms of Shingles will usually go away within a few weeks, some experience nerve pain that can last years.
The disease is caused by a reactivation of the varicella zoster virus (VZV), the initial exposure of which causes chicken pox. The reason why the VZV virus reactivates is not widely understood by the medical community, although it is understood to occur more in the elderly and those with a compromised immune system.
There have been several vaccines created to prevent Shingles. As of 2017, a new vaccine called Shingrix was approved for patients over 50 years of age and can prevent most cases of Shingles. Once Shingrix was approved for use, it later became the preferred vaccine according to the Center for Disease Control (CDC). Unfortunately, it has been involved in Maryland pharmacy errors and errors in other states.
