Shingrix is a vaccine that is used to protect against shingles, a painful rash caused by the reactivation of the varicella-zoster virus. While the vaccine is highly effective, it can also cause side effects in some individuals. The timing of these side effects can vary from person to person, but in general, they typically start within a few hours to a few days after receiving the vaccine. In this article, we will explore the common side effects of Shingrix and when they typically occur.
What is Shingrix?
Shingrix is a vaccine that is used to protect against shingles, a viral infection that causes a painful rash. Shingles is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. Shingles typically affects adults who have had chickenpox in the past, but it can also occur in individuals who have never had chickenpox.
How does Shingrix Work?
Shingrix works by stimulating the immune system to produce antibodies that can fight the varicella-zoster virus, which is the virus that causes shingles. The vaccine contains a protein found on the surface of the virus called glycoprotein E (gE). When the vaccine is administered, gE stimulates the immune system to produce antibodies that can recognize and destroy the varicella-zoster virus.
These antibodies remain in the body and provide protection against the virus. If the virus reactivates and attempts to cause shingles, the antibodies can quickly recognize and neutralize it, preventing the development of the disease.
In addition to producing antibodies, Shingrix also activates other immune cells, such as T cells, which can further enhance the body’s ability to fight the virus. The vaccine is administered as a series of two doses, with the second dose given 2-6 months after the first, to ensure that the immune system is fully primed to provide protection against the varicella-zoster virus.
How Soon do side effects start after Shingrix?
These side effects usually start within a few days of getting vaccinated and can last for several days. In rare cases, more serious side effects can occur, such as allergic reactions or Guillain-Barré syndrome, but these are usually short-lived and resolve on their own.
Shingrix Side Effects
Shingrix is a safe and effective vaccine, but like any vaccine, it can cause side effects in some individuals. The most common side effects of Shingrix include:
- Pain, redness, or swelling at the injection site
- Muscle pain
- Shivering or fever
These side effects are generally mild to moderate in severity and usually resolve within a few days. In rare cases, more serious side effects can occur, including allergic reactions. Signs of an allergic reaction include difficulty breathing, swelling of the face or throat, and hives or a rash. If you experience any of these symptoms after receiving the Shingrix vaccine, seek medical attention immediately.
Serious side effects of Shingrix
While serious side effects of the Shingrix vaccine are rare, they can occur. Some of the more serious side effects that have been reported include:
- An allergic reaction, which can cause difficulty breathing, swelling of the face or throat, and hives or a rash. Anaphylaxis, a severe and potentially life-threatening allergic reaction, has been reported in rare cases.
- Guillain-Barré syndrome (GBS), a rare neurological disorder that can cause muscle weakness and paralysis. Although the risk of developing GBS after receiving the Shingrix vaccine is low, cases have been reported.
- Ocular complications, such as uveitis (inflammation of the eye) and keratitis (inflammation of the cornea). These complications are also rare but have been reported in some individuals who received the vaccine.
Why is getting Shingrix so Important?
Getting the Shingrix vaccine is important because it provides highly effective protection against shingles and its complications. Shingles is a viral infection caused by the varicella-zoster virus, the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains dormant in the body and can reactivate later in life, causing shingles.
Shingles is a painful and often debilitating condition that can cause a rash, blisters, and nerve pain. It can also lead to more serious complications, such as postherpetic neuralgia (PHN), a condition in which nerve pain persists long after the rash has healed. PHN can be a chronic and disabling condition that significantly reduces quality of life.
The Shingrix vaccine is highly effective at preventing shingles and its complications, with studies showing it to be more than 90% effective in preventing shingles and PHN. The vaccine is recommended for all adults aged 50 years and older, even if they have previously received the older shingles vaccine, Zostavax.
By getting vaccinated with Shingrix, individuals can significantly reduce their risk of developing shingles and its complications, including PHN. This can help them maintain their quality of life and avoid the pain and discomfort associated with this condition.
Who should avoid the Shingrix vaccine?
While the Shingrix vaccine is safe for most people, there are some individuals who should avoid or delay getting the vaccine. These include:
- Anyone who has had a severe allergic reaction (anaphylaxis) to any component of the vaccine or after a previous dose of the vaccine.
- Anyone who has a weakened immune system due to a medical condition or medication. This includes individuals with HIV/AIDS, cancer, and autoimmune disorders, as well as those receiving immunosuppressive therapy.
- Anyone who is currently experiencing an acute illness or infection with a fever. The vaccine should be delayed until the illness has resolved.
