Should I Get the RSV Vaccine While Pregnant?

When It Makes Sense

• Good fit: You are in the later part of pregnancy during RSV season and want to help protect your baby from birth through the first several months of life. Maternal vaccination can pass protective antibodies to the infant before delivery.
• Good fit: You prefer a single prenatal step that may reduce the chance of severe RSV in your newborn, rather than scheduling an infant treatment after birth. Some parents find it easier to handle vaccination during an existing prenatal visit.

When You Should Avoid It

• Warning sign: You are outside the recommended gestational window for maternal RSV vaccination. Current guidance focuses on specific weeks of pregnancy, so timing matters. If you are too early or have already delivered, the maternal vaccine is not the right tool.
• Warning sign: You have a history of severe allergic reactions to vaccine components, or you are experiencing a high fever or acute illness at the time of a scheduled vaccination. In these cases, your provider may advise delaying or choosing the infant antibody option instead.

Pros and Cons

Pros

• May reduce the risk of severe RSV illness in your baby during the first months of life, when infants are most vulnerable to breathing complications.
• Can be coordinated with routine prenatal care, so it does not require a separate appointment for your newborn after birth.

Cons

• Timing is limited to a specific pregnancy window, so it cannot be given too early or after delivery.
• Side effects can include soreness at the injection site, fatigue, headache, or muscle aches, and some people prefer to wait for the infant antibody option instead.

Decision Checklist

• Am I within the recommended gestational age window for maternal RSV vaccination, and will I still be pregnant during RSV season?
• Would I prefer to handle protection during pregnancy, or would I rather rely on an infant monoclonal antibody administered to my baby after birth?
• Have I reviewed my allergy history, current symptoms, and overall pregnancy health with my obstetric or primary care provider?

Alternatives to Consider

The main alternative is a long-acting monoclonal antibody given to the infant after birth, which is designed to provide protection during the first RSV season. Some families choose this option because it avoids another injection during pregnancy. Good hand hygiene, limiting newborn exposure to sick contacts, and avoiding crowded indoor spaces during peak RSV season are also practical, non-medical ways to lower risk. These alternatives can also be combined with vaccination or antibody treatment depending on your provider’s advice.

Final Recommendation

Maternal RSV vaccination is a reasonable option for many pregnant people who are in the recommended window and will deliver during or just before RSV season. However, it is not the only path, and the infant monoclonal antibody is an effective alternative. Because pregnancy health, timing, and local RSV patterns vary, discuss your options with a qualified prenatal care provider before making a decision.
