RSV Vaccine Side Effects in Adults: What to Expect
Most side effects experienced after receiving an RSV vaccine are mild and temporary, typically resolving within a few days. These common side effects are often manageable and shouldn’t deter you from getting vaccinated. However, knowing what to expect can help alleviate anxiety and ensure you’re prepared.

- Fever: A mild fever is possible.
- Underarm Swelling or Tenderness: This side effect has been reported more frequently with mRESVIA (Moderna).

Serious Side Effects of RSV Vaccines in Adults: A Closer Look
While the vast majority of side effects are mild, it’s crucial to be aware of the possibility of serious side effects, although these are rare.
- Guillain-Barré Syndrome (GBS): This is perhaps the most concerning serious side effect reported in clinical trials for Arexvy and Abrysvo.
- Anaphylaxis/Severe Allergic Reactions: As with any vaccine, there’s a small risk of severe allergic reactions, including anaphylaxis.
- Fainting (Syncope): Fainting can occur after any injectable vaccine, including RSV vaccines.
- Potential Risk of Preterm Birth (Abrysvo): In pregnant women, Abrysvo may slightly increase the risk of preterm birth.
- Worsening of Pre-existing Conditions: Individuals with asthma or COPD should discuss the potential risks and benefits of RSV vaccination with their doctor.
