Shingles is a painful and often debilitating condition caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. After an individual recovers from chickenpox, the virus remains dormant in the body and can reactivate years later, leading to shingles. While the infection itself results in a painful rash, it can also lead to complications like postherpetic neuralgia (PHN), a condition that causes prolonged nerve pain. Fortunately, the shingles vaccine is one of the most effective ways to reduce the risk of developing shingles and its complications. But when is the best time to get vaccinated for maximum effectiveness?
Understanding the Risks of Shingles
Shingles primarily affects older adults, particularly those over the age of 50, as the immune system weakens with age, making it more difficult to fight off the dormant chickenpox virus. Though shingles can occur at any age, it is more common and tends to be more severe in individuals over 60. In fact, approximately one in three people will develop shingles in their lifetime, and the risk increases with age. The pain associated with shingles can last for weeks or even months, and complications like PHN can persist for years, significantly impacting a person’s quality of life.
The Shingles Vaccine: What You Need to Know
The shingles vaccine is crucial in preventing the infection and reducing the severity of its symptoms. There was previously a vaccine called Zostavax, a live vaccine, but it was discontinued in 2020 and is no longer in use in the U.S. as of that year. The vaccine currently recommended is Shingrix, a recombinant (non-live) vaccine, which is preferred due to its higher efficacy, particularly in older adults.
Shingrix is recommended for adults aged 50 and older, regardless of whether they have previously had shingles or chickenpox. The vaccine is administered in two doses, with the second dose given two to six months after the first. Clinical studies have shown that Shingrix is more than 90% effective at preventing shingles and postherpetic neuralgia, offering long-lasting protection, even in older adults.
New Data on Shingrix Efficacy
Recent data shows that Shingrix can provide at least 10 years of protection against shingles in adults aged 50 years and older. This new information further underscores the vaccine’s long-lasting efficacy, offering extended protection against this painful condition.
The Best Age to Get Vaccinated
The Centers for Disease Control and Prevention (CDC) now recommends that all adults aged 50 and older get vaccinated with Shingrix. Though previously the vaccine was recommended for those aged 60 and older, new data has expanded the recommendation to include those aged 50 to 59, as they are also at risk. According to the CDC, the shingles vaccine is 97% effective in adults between the ages of 50 to 69 with healthy immune systems. Getting vaccinated before turning 60 helps protect individuals before their risk of shingles rises significantly.
Why Timing Matters
Getting vaccinated early—before the onset of shingles—ensures that the body has time to develop the necessary antibodies to fight off the virus. Delaying vaccination could increase the chances of getting shingles and its painful complications. Studies have shown that Shingrix remains highly effective for at least four years after vaccination, and potentially even longer, providing long-term protection as individuals age.
Side Effects of the Shingles Vaccine
As with any vaccine, there can be side effects. The most common reactions to Shingrix include soreness at the injection site, redness, and swelling. Some people may experience mild flu-like symptoms, such as fever, fatigue, or headache. These side effects are typically short-lived and subside within a few days. Serious side effects are rare, but as with any medical intervention, it’s important to discuss any concerns with a healthcare provider.
Conclusion
The Shingrix vaccine is a highly effective way to prevent shingles and its complications. While it is recommended for anyone aged 50 and older, it is most beneficial for those who are 60 and older, as this group is at the highest risk for shingles. However, given new evidence of long-lasting protection, individuals aged 50 and older should consider getting vaccinated as early as possible to ensure they are protected in the years to come. If you’re over 50 and haven’t yet received your shingles vaccine, talk to your healthcare provider to discuss how this vaccine can help protect your health and well-being.
