The Shingrix vaccine is a two-dose series approved by the FDA for shingles prevention. It is recommended for adults aged 50 and older, as well as those 18 and older who are at an increased risk due to a weakened immune system. This vaccine is highly effective, offering over 90% protection against shingles and its associated complications, such as postherpetic neuralgia, a form of long-term nerve pain.
Onset of Side Effects
After receiving the shingles vaccine, individuals experience side effects relatively quickly. These reactions often begin within a few hours to a day following the injection. While side effects can occur after either the first or second dose, they are sometimes reported more frequently or intensely after the second dose.
Common Side Effects and Their Duration
The shingles vaccine commonly causes both local reactions at the injection site and broader systemic effects throughout the body. At the injection site, it is common to experience pain, redness, and swelling. These local reactions are generally mild to moderate.
Beyond the injection site, systemic side effects can include muscle aches, fatigue, headache, shivering, and fever. Some individuals also report upset stomach or nausea. Most of these side effects are temporary, typically resolving on their own within two to three days.
Managing Vaccine Side Effects
To alleviate discomfort from shingles vaccine side effects, several measures can be taken. Applying a cool compress or ice pack to the injection site can help reduce localized pain, redness, and swelling. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, are generally effective for managing pain, headaches, and muscle aches.
Resting and staying well-hydrated can support the body’s recovery process. While side effects might temporarily affect daily activities, continuing with the second dose is recommended even if a reaction occurs after the first, as this ensures full protection.
When to Contact a Doctor
While most side effects are mild and temporary, seek medical advice in specific instances. Contact a healthcare provider if side effects worsen, do not improve, or persist beyond a few days, typically after two to five days. It is also important to be aware of signs of a severe allergic reaction, such as hives, swelling of the face or throat, difficulty breathing, a fast heartbeat, or dizziness. These symptoms require immediate medical attention. Any other concerning or severe symptoms also warrant a doctor’s call.
