Shingrix, a vaccine designed to protect against shingles (herpes zoster), has been widely recommended for adults aged 50 and over. The vaccine has proven to be highly effective in preventing this painful condition, which results from the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox. Despite its efficacy, some individuals have reported experiencing fatigue after receiving the Shingrix vaccine. In this article, we will explore the possible connection between Shingrix and fatigue, delve into the vaccine’s side effects, and provide an overview of what recipients can expect.
Understanding Shingrix
What is Shingrix?
Shingrix is a recombinant, adjuvanted vaccine that contains a glycoprotein E antigen and an adjuvant system (AS01B) to enhance the body’s immune response. Unlike the older shingles vaccine (Zostavax), which is a live attenuated vaccine, Shingrix is non-live and therefore safer for immunocompromised individuals.
How Does Shingrix Work?
Shingrix works by stimulating the immune system to recognize and fight the varicella-zoster virus if it reactivates. The glycoprotein E antigen targets the virus, while the adjuvant boosts the immune system’s response. This dual action makes Shingrix more effective, providing over 90% protection against shingles in older adults.
Common Side Effects of Shingrix
Local Reactions
One of the most common side effects of Shingrix is a reaction at the injection site. This can include:
- Redness
- Swelling
- Pain
These symptoms are generally mild to moderate and resolve within a few days.
Systemic Reactions
In addition to local reactions, Shingrix can cause systemic side effects, which are effects that affect the entire body. These include:
- Fever
- Muscle pain
- Headache
- Chills
- Nausea
These symptoms typically occur within a few days of vaccination and are usually mild to moderate in intensity.
Fatigue
Fatigue, or a general feeling of tiredness, is also listed as a common side effect of Shingrix. This symptom is often reported within the first few days after receiving the vaccine and can vary in severity from mild to moderate.
Fatigue After Shingrix: Exploring the Evidence
Clinical Trials
During clinical trials, fatigue was reported by a significant number of participants. According to the data, about 33.7% of participants experienced fatigue after receiving Shingrix. This suggests that fatigue is a relatively common reaction to the vaccine.
Post-Marketing Surveillance
After Shingrix was approved and began to be used widely, post-marketing surveillance data continued to support the finding that fatigue is a common side effect. Many recipients reported feeling unusually tired after getting the vaccine, often accompanied by other systemic symptoms like muscle pain and headache.
Mechanism of Fatigue
The exact mechanism by which Shingrix causes fatigue is not fully understood. However, it is believed to be related to the body’s immune response to the vaccine. The adjuvant in Shingrix is designed to enhance the immune response, which can lead to an increase in inflammatory cytokines. These cytokines are involved in the immune response but can also cause symptoms like fatigue as a side effect.
Managing Fatigue After Shingrix
Rest and Hydration
For most individuals, the fatigue associated with Shingrix is temporary and resolves on its own. Resting and staying well-hydrated can help alleviate the symptoms.
Over-the-Counter Pain Relievers
If fatigue is accompanied by muscle pain or headache, over-the-counter pain relievers such as ibuprofen or acetaminophen can be helpful. However, it is always advisable to consult with a healthcare provider before taking any medication.
When to Seek Medical Advice
While fatigue and other side effects of Shingrix are usually mild to moderate, there are instances where medical advice should be sought. If the fatigue is severe, persistent, or accompanied by other worrying symptoms, it is important to contact a healthcare provider.

Shingrix: Balancing Benefits and Side Effects
Efficacy of Shingrix
Despite the potential side effects, the benefits of Shingrix far outweigh the risks for most individuals. Shingles can be a debilitating condition, causing severe pain and complications such as postherpetic neuralgia (PHN), which can last for months or even years after the initial rash has healed. Shingrix has been shown to significantly reduce the risk of developing shingles and PHN.
Individual Considerations
Deciding to get the Shingrix vaccine should involve a discussion with a healthcare provider, taking into account individual health conditions and potential risks. For most people, the temporary side effects, including fatigue, are a small price to pay for the long-term protection against shingles.
Conclusion
Does Shingrix make you tired? Yes, fatigue is a common side effect of the Shingrix vaccine, reported by about one-third of recipients. This tiredness is generally mild to moderate and resolves within a few days. Understanding and managing this side effect can help individuals prepare for their vaccination and ensure they reap the full benefits of protection against shingles.
The overall efficacy of Shingrix, coupled with its ability to prevent the severe pain and complications associated with shingles, makes it a valuable vaccine for older adults. While fatigue can be an inconvenient side effect, the protection offered by Shingrix far outweighs this temporary discomfort. As always, any concerns or questions about vaccination should be discussed with a healthcare provider to ensure the best possible outcome for each individual.
