Common side effects from the RSV vaccine include fever, fatigue, headaches, and muscle or joint pain. Some individuals may experience nausea or diarrhea. These symptoms are typically mild. If you experience bothersome side effects after vaccination, they can generally be treated with over-the-counter medications. Ask your pharmacist for assistance with product selection.
If symptoms are severe or persist for more than a few days, seek medical advice. Some research suggests that there is a risk of Guillain-Barre Syndrome (GBS) or similar inflammatory neurologic events, but research is underway by the CDC to confirm this. GBS is a rare condition in which your immune system attacks your nerves, causing symptoms such as weakness. At this time, an increased risk of GBS cannot be confirmed. Additional post-marketing surveillance is underway to provide more information. The CDC and FDA will share data on RSV vaccine safety as it becomes available.
