Shingles is a painful condition caused by the varicella-zoster virus, the same virus that causes chickenpox. Once you’ve had chickenpox, the virus remains dormant in your body and can reactivate later in life, causing shingles. The shingles vaccine was developed to prevent this painful condition. Many people wonder if they can take the shingles vaccine more than once, especially if they have received it in the past and are still concerned about the risk of getting shingles. This article will explore whether it’s safe and effective to take the shingles vaccine more than once, along with some additional details about the vaccine itself.
Understanding Shingles and Its Risks
Before discussing the shingles vaccine, it’s important to understand what shingles is and why the vaccine is necessary. Shingles is a viral infection that causes a painful rash, usually appearing on one side of the body. The rash typically starts as red patches, which later develop into blisters that can burst and form scabs. The pain associated with shingles can be intense, and in some cases, people experience lingering pain even after the rash has healed, known as postherpetic neuralgia.
The risk of developing shingles increases as people get older. After the age of 50, the immune system weakens, and the varicella-zoster virus becomes more likely to reactivate. In fact, about one in three people will develop shingles in their lifetime, and the risk increases with age. This is why the shingles vaccine is recommended, particularly for those over the age of 50.
The Shingles Vaccine: What It Does
The shingles vaccine is designed to reduce the risk of developing shingles. It helps to strengthen the immune system’s defense against the varicella-zoster virus, which can lie dormant in nerve cells after a person has had chickenpox. There are two main types of shingles vaccines: Zostavax and Shingrix.
Zostavax: This vaccine was the first shingles vaccine to be approved by the FDA. It is a live attenuated vaccine, which means it contains weakened live virus. Zostavax was recommended for people aged 60 and older and was found to reduce the risk of developing shingles by about 50%. However, its effectiveness decreases over time, especially in older adults.
Shingrix: This is the newer shingles vaccine, recommended for people aged 50 and older. Unlike Zostavax, Shingrix is a non-live vaccine that contains a viral protein from the varicella-zoster virus. It has been shown to be much more effective than Zostavax, providing up to 90% protection against shingles and its complications, including postherpetic neuralgia. Shingrix is given in two doses, spaced two to six months apart.
Shingrix is the preferred vaccine because it is more effective and provides longer-lasting protection than Zostavax. It is now recommended even for people who have previously received Zostavax, as Shingrix provides a stronger and more reliable defense against shingles.
Can You Take the Shingles Vaccine More Than Once?
The short answer is yes, you can take the shingles vaccine more than once, but it depends on the type of vaccine and your individual health situation. Here’s what you need to know:
For People Who Have Already Had Shingles
If you have already had shingles, you may be wondering if you need to get the vaccine. While having shingles once doesn’t necessarily prevent you from having it again, getting the vaccine can help lower your risk of developing shingles again. The vaccine boosts your immune response to the varicella-zoster virus, reducing the chances of reactivation.
Even if you have had shingles in the past, getting vaccinated is still recommended. If you have already received Zostavax in the past, getting Shingrix can be a good idea. Research shows that Shingrix provides stronger protection and can be safely given to individuals who have already had shingles.
If You Have Received Zostavax in the Past
Zostavax was the first shingles vaccine, but it is no longer the preferred option due to its reduced effectiveness over time. If you received Zostavax years ago, you can still take Shingrix. In fact, it is recommended to receive the Shingrix vaccine, even if you have previously received Zostavax. The two vaccines work differently, and Shingrix provides stronger protection.
There is no harm in receiving Shingrix after Zostavax, and it is considered safe. The Centers for Disease Control and Prevention (CDC) recommends that individuals aged 50 and older receive the Shingrix vaccine, regardless of whether they have received Zostavax.
Can You Take Shingrix More Than Once?
Shingrix is given in two doses. Once you’ve received both doses, the protection from the vaccine lasts for several years. However, it is not currently recommended to take more than two doses of Shingrix. The two-dose regimen is sufficient to provide long-term protection against shingles.
If you are concerned about the effectiveness of the vaccine, it is always a good idea to talk to your healthcare provider. They can help you understand if you might benefit from any additional vaccines or preventive measures. However, there is no evidence to suggest that taking Shingrix more than twice would provide extra benefit.
What Happens If You Get Shingles After Being Vaccinated?
While the shingles vaccine significantly reduces the risk of developing shingles, it is not a 100% guarantee. In some cases, people who have received the vaccine may still develop shingles, but the severity of the disease is usually lessened. Vaccinated individuals are less likely to experience complications such as postherpetic neuralgia, and their shingles outbreaks are typically shorter and less painful.
If you do develop shingles after being vaccinated, it’s important to consult with your healthcare provider. In some cases, you may still be able to benefit from antiviral treatment to reduce the duration and severity of the symptoms.
Are There Any Risks to Taking the Shingles Vaccine?
Like all vaccines, the shingles vaccine carries some risks, though serious side effects are rare. The most common side effects of the shingles vaccine include:
- Pain or swelling at the injection site
- Redness at the injection site
- Fever
- Fatigue
- Headache
- Muscle aches
These side effects are generally mild and go away within a few days. In very rare cases, people may experience more serious side effects, such as an allergic reaction, but these are uncommon. If you experience severe symptoms, such as difficulty breathing, swelling of the face or throat, or dizziness, you should seek medical help immediately.
Certain people should not receive the shingles vaccine, including those who are pregnant, breastfeeding, or have a weakened immune system. If you have any health concerns or are unsure whether the vaccine is right for you, consult with your healthcare provider.
Conclusion
In summary, yes, you can take the shingles vaccine more than once, depending on your situation. If you have received Zostavax in the past, it is recommended that you get Shingrix for stronger and longer-lasting protection. Shingrix is given in two doses, and after completing the two-dose series, there is no need for additional doses. While the shingles vaccine is highly effective, it is not a guarantee, and some individuals may still develop shingles. However, vaccinated individuals tend to experience milder cases and fewer complications.
If you are concerned about shingles or the vaccine, speak to your doctor to determine the best course of action for your health and well-being. Vaccination is an important step in reducing your risk of shingles and the associated complications, especially as you age.
