Shingrix is a recombinant subunit vaccine that contains a small part of the varicella-zoster virus (VZV) and an adjuvant, which enhances the immune response to the vaccine. The vaccine is highly effective at preventing shingles and its complications, such as post-herpetic neuralgia, in people over the age of 50.
Like all vaccines, Shingrix can cause side effects, but the majority of people who receive the vaccine experience only mild or moderate side effects that usually go away on their own within a few days. The most common side effects of Shingrix include:
- Pain, redness, or swelling at the injection site
- Fatigue
- Headache
- Muscle pain
- Shivering
- Fever
These side effects typically appear within the first two to three days after receiving the vaccine and can last for up to a week. The severity and duration of the side effects can vary from person to person, but they are usually mild to moderate.
It is important to note that serious side effects from Shingrix are rare. According to the Centers for Disease Control and Prevention (CDC), less than 1% of people who receive Shingrix experience serious side effects, such as an allergic reaction. However, it is still important to be aware of the potential side effects of the vaccine and to report any serious side effects to your healthcare provider immediately.
The injection site reactions, such as pain, redness, and swelling, are the most common side effects of Shingrix. These reactions occur in up to 80% of people who receive the vaccine and usually resolve within a few days. The severity of the injection site reactions can vary from person to person, but they are usually mild to moderate and do not interfere with daily activities.
Fatigue, headache, and muscle pain are also common side effects of Shingrix. These symptoms typically appear within the first two to three days after receiving the vaccine and can last for up to a week. In most cases, these symptoms are mild to moderate and do not require medical attention.
Shivering and fever are less common side effects of Shingrix, occurring in about 10% to 20% of people who receive the vaccine. These symptoms usually appear within the first two to three days after receiving the vaccine and can last for up to a week. In most cases, these symptoms are mild to moderate and do not require medical attention.
It is important to note that the side effects of Shingrix are generally more common and more severe after the second dose of the vaccine. This is because the second dose of the vaccine is a booster dose, which is designed to enhance the immune response to the vaccine. However, the side effects of the second dose are usually still mild to moderate and resolve within a few days.
In rare cases, Shingrix can cause serious side effects, such as an allergic reaction. Symptoms of an allergic reaction can include difficulty breathing, swelling of the face or throat, rapid heartbeat, and hives. If you experience any of these symptoms after receiving the vaccine, seek medical attention immediately.
In summary, the side effects of Shingrix typically appear within the first two to three days after receiving the vaccine and usually resolve within a week. The most common side effects include injection site reactions, fatigue, headache, muscle pain, shivering, and fever. Serious side effects are rare but should be reported to a healthcare professional immediately if they occur.
