Shingrix Vaccine for Shingles
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the Shingrix vaccine to determine its effects on specific immune cells in the skin and blood. It targets individuals seeking to prevent shingles, a painful rash caused by the same virus as chickenpox. The trial includes two groups: adults aged 30-40 and those 70 and older. All participants must be HIV-negative and must not have received certain previous vaccines. This trial suits those who have not been vaccinated for shingles or chickenpox and fall within these age groups. As a Phase 4 trial, this research aims to understand how the already FDA-approved and effective Shingrix vaccine benefits more patients.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on long-term use of oral or parenteral steroids, high-dose inhaled steroids, or medications that may cause bleeding, you may not be eligible to participate.

What is the safety track record for the Shingrix vaccine?
Research has shown that Shingrix, a vaccine to prevent shingles, is generally safe. Studies have found that Shingrix is more than 90% effective in preventing shingles in adults aged 50 and older, demonstrating its high efficacy.
The FDA has approved the vaccine for this age group, confirming its safety. Shingrix might cause temporary discomfort, such as pain, redness, and swelling at the injection site. Some individuals may also experience muscle pain, tiredness, headaches, or a slight fever. These side effects are usually mild and resolve on their own.
Overall, Shingrix is considered safe and well-tolerated based on its approval and widespread use.12345Why are researchers enthusiastic about this study treatment?
Shingrix is unique because it provides stronger and longer-lasting protection against shingles compared to older vaccines like Zostavax. Unlike Zostavax, which is a live attenuated vaccine, Shingrix is a recombinant vaccine that uses a non-live antigen and an adjuvant system to boost the body's immune response. This makes Shingrix especially effective for older adults, who are at higher risk for shingles and may have weaker immune systems. Researchers are excited about Shingrix because it has shown over 90% efficacy in preventing shingles, offering a more reliable option for reducing the incidence of this painful condition.
What is the effectiveness track record for the Shingrix vaccine for shingles?
Studies have shown that Shingrix is highly effective in preventing shingles. Research indicates that Shingrix prevents shingles in adults over 90% of the time. In another study, the vaccine reduced the risk of postherpetic neuralgia (a painful condition following shingles) by 91.2% compared to a placebo. For adults over 50, two doses of Shingrix provided about 74% protection against shingles. Overall, Shingrix serves as a strong defense against shingles and its complications. Participants in this trial will be divided into two cohorts based on age: one cohort for those aged 30-40 and another for those 70 years or older.678910

Are You a Good Fit for This Trial?
This trial is for healthy adults in two age groups: 30-40 and 70 or older, who do not have HIV. Participants should not have active hepatitis B or C, history of organ transplants, be immunosuppressed due to illness or drugs, pregnant, planning pregnancy soon after vaccination, prone to excessive scarring or bleeding disorders. They must also never have received a Shingrix vaccine before.Inclusion Criteria
