Shingles is an infectious disease that can cause a rash on the body. The rash will often be characterized by pain, tingling, and numbness. People may also experience severe itching. A person may experience fever and chills in severe cases, as well. It can also cause a headache and stomach pain.
Most people will experience shingles once in their lifetime. However, a shingles vaccine can reduce the risk. It is usually recommended for adults over 50 and may also be given to younger people with a weakened immune system. The vaccine may lead to a milder rash and a lower risk of postherpetic neuralgia, which is an intense, chronic pain caused by the rash. While the shingles vaccine can cause temporary side effects, most are mild and disappear within two to three days. According to Coherent Market Insights the Shingles Vaccine Market Global Industry Insights, Trends, Outlook, and Opportunity Analysis, 2022-2028. Shingles can affect many internal organs, including the eyes, nose, and throat. If it attacks the eye or face, it can result in temporary blindness or eye inflammation. The pain is caused by damaged nerve fibers in the skin. People with this type of rash should see a doctor as soon as possible to avoid compromising their eyesight. Shingrix vaccine reduces the risk of postherpetic neuralgia, or PHN. This disease is often caused by a virus called varicella zoster, which can lead to chronic pain and complications. Shingrix has a higher % of protection against shingles, as compared to Zostavax. This recombinant zoster vaccine is more effective at preventing shingles in adults aged 50-69, and has a higher efficacy rate than Zostavax for adults aged 70 years and above. It also offers strong protection against PHN, the most common complication of shingles. Zostavax was approved by the Food & Drug Administration in 2006 and is no longer available in the U.S., whereas Shingrix, on the other hand, was approved in 2017. Both vaccines contain weakened live shingles virus, which causes the body's immune system to produce a protective response to shingles. Both vaccines are one-time shots and protect people against PHN and shingles. The Shingles vaccine has been proven effective in preventing shingles-related postherpetic neuralgia (PhN). It has been shown to protect 91% of shingles-affected individuals from PHN. It is recommended to get two doses of the vaccine, separated by two to six months, to prevent the development of PHN. Herpes zoster is a major health problem and a considerable economic burden, vaccination is therefore a priority. The effectiveness of a shingles vaccine has been evaluated against both the incidences of postherpetic neuralgia (PhN) and postherpetic neuralgia (HR). There is no specific treatment for PHN, a combination of medications, including anticonvulsant drugs, can help reduce the symptoms. In one study, patients who took amitriptyline within 48 hours of rash development were found to have fewer postherpetic neuralgia at six months. However, the medication is not without side effects, especially for older patients. The study included 284 subjects. The participants in both groups had an average age of 69 years. Forty-seven percent of subjects were over 70 years old, and 6.5% were over 80 years old. Despite the high age of the subjects, the vaccine showed 91% efficacy at preventing postherpetic neuralgia (PHN). Shingrix vaccine is more effective than Zostavax and costs less than $212 per dose. It is covered by Medicare and Medicaid, and many private health insurance plans also cover it. This vaccine can prevent postherpetic neuralgia, a painful complication of shingles. However, people should be aware of the side effects of this vaccine.
