Shingles, also known as herpes zoster, is a painful skin condition that can cause a rash, blisters, and severe discomfort. It occurs when the varicella-zoster virus, which causes chickenpox, reactivates in the body. This virus can stay dormant in your nerves after a chickenpox infection and reactivate later in life. While shingles can happen to anyone who has had chickenpox, the risk increases as people age, especially for those over 50.
Fortunately, there is a vaccine available that can help reduce the risk of shingles. The vaccine, called the Shingrix vaccine, is designed to boost the immune system’s ability to fight off the varicella-zoster virus. However, some people may still wonder, “Can you still get shingles if you had the vaccine?” In this article, we will explore the effectiveness of the shingles vaccine, its benefits, and the possibility of still getting shingles after vaccination.
Understanding Shingles and the Vaccine
Shingles is caused by the reactivation of the varicella-zoster virus, which most people get in childhood as chickenpox. After the chickenpox infection resolves, the virus remains dormant in the body’s nerve tissue. As you age or if your immune system weakens, the virus may reactivate, leading to shingles. Shingles typically appears as a painful rash, usually on one side of the body or face, and can last for several weeks.
The shingles vaccine, Shingrix, is a newer and more effective version compared to older vaccines like Zostavax. Shingrix is recommended for adults aged 50 and older, even if they have had shingles before or received the previous vaccine. The vaccine is made from a recombinant version of the varicella-zoster virus, which means it doesn’t contain the live virus. Instead, it stimulates the immune system to produce a strong immune response that helps prevent shingles.
Shingrix is given as a two-dose series, with the second dose administered two to six months after the first. It is highly effective in reducing the risk of developing shingles and its complications, such as postherpetic neuralgia (PHN), a type of nerve pain that can persist even after the rash heals.
How Effective Is the Shingles Vaccine?
Shingrix has been shown to be highly effective in preventing shingles. According to studies, it is more than 90% effective in preventing shingles in adults aged 50 and older. The vaccine’s effectiveness remains strong even in older adults, who are at a higher risk of developing shingles. Additionally, Shingrix is about 90% effective in preventing PHN, which is a common complication of shingles.
However, while the vaccine significantly reduces the risk of getting shingles, it does not guarantee complete protection. No vaccine is 100% effective. Some vaccinated individuals may still develop shingles, though their cases are typically less severe and the risk of complications is lower compared to those who are unvaccinated.
Can You Still Get Shingles After the Vaccine?
The short answer is yes, you can still get shingles after receiving the Shingrix vaccine. While the vaccine is highly effective in preventing shingles, it does not offer absolute protection. The likelihood of developing shingles after vaccination is low, but it is not impossible.
There are a few reasons why someone might still get shingles despite being vaccinated:
Immune System Factors: The immune system weakens naturally as you age, and in some cases, the body may not produce enough of the immune response to fully prevent shingles. Certain health conditions, such as cancer, HIV, or immunosuppressive treatments (e.g., chemotherapy or steroids), can also impair the immune system, making it more difficult for the vaccine to work as effectively.
Time After Vaccination: The effectiveness of the Shingrix vaccine can decrease over time, especially as more years pass after vaccination. While the vaccine provides strong protection for at least five years, some studies suggest that immunity may wane over time. However, even if the vaccine’s effectiveness decreases, it still offers protection against severe outcomes of shingles.
Vaccine Response: Not everyone’s immune system responds equally to vaccines. Some individuals may not develop the full protective immune response after receiving the Shingrix vaccine, leaving them at a slightly higher risk of developing shingles.
Other Factors: In rare cases, factors like exposure to stress, illness, or other triggers can cause the dormant virus to reactivate, even if you’ve been vaccinated.
What Happens If You Get Shingles After the Vaccine?
If you develop shingles after receiving the Shingrix vaccine, the case is likely to be less severe than it would have been without the vaccine. Most people who experience shingles after vaccination report fewer blisters, less pain, and a quicker recovery time.
Additionally, the risk of developing complications like postherpetic neuralgia (PHN) is significantly reduced. PHN is a condition where the nerve pain caused by shingles lasts long after the rash has healed. It can be debilitating and difficult to treat. Since Shingrix is highly effective at reducing PHN, even those who get shingles after vaccination are less likely to experience long-term nerve pain.
Why You Should Still Get the Vaccine
Even though the vaccine doesn’t guarantee complete protection against shingles, there are several important reasons why you should still consider getting vaccinated:
Reduced Risk of Shingles: The Shingrix vaccine significantly lowers the risk of developing shingles. Even if you do get shingles after vaccination, the severity and duration of the disease are much lower.
Prevention of Complications: Shingles can lead to serious complications, including PHN, which can cause long-lasting nerve pain. The vaccine greatly reduces the risk of these complications, even in those who do develop shingles.
Protection for Older Adults: The risk of developing shingles increases as you age. The vaccine is particularly important for older adults, who are more likely to experience severe cases of shingles and complications like PHN.
Long-Lasting Protection: Studies show that Shingrix provides strong protection for at least five years, and it may last even longer. The vaccine also offers ongoing protection against the most severe forms of shingles.
Should You Get the Vaccine If You’ve Already Had Shingles?
Yes, even if you have had shingles before, it is still recommended to get the vaccine. Having shingles once does not guarantee immunity from future outbreaks. In fact, shingles can occur more than once in a person’s lifetime. The Shingrix vaccine can help protect you from getting shingles again, and it can also reduce the severity if you do experience a recurrence.
The Centers for Disease Control and Prevention (CDC) recommends that adults 50 and older receive the Shingrix vaccine, regardless of whether they’ve had shingles in the past.
Conclusion
While the Shingrix vaccine is highly effective in preventing shingles and its complications, it is still possible to get shingles after vaccination. However, the risk of developing shingles is significantly reduced, and if shingles do occur, the symptoms are likely to be milder. The vaccine’s ability to prevent long-term nerve pain and other complications makes it an important step in protecting your skin health and overall well-being as you age.
If you are over the age of 50 or have a weakened immune system, it is highly recommended to receive the Shingrix vaccine. Even though it cannot provide 100% protection, it remains one of the best defenses against shingles and its painful consequences. Always consult with your healthcare provider to determine the best course of action for your individual health needs.
