It's important to speak with your high-risk baby's doctor about your baby's risk of getting severe RSV disease. Your doctor may take steps, including prescribing and getting your high-risk baby started on Synagis, to help protect against severe RSV disease.

Synagis is not a vaccine; it works differently. Synagis gives your high-risk baby a dose of virus-fighting substances called antibodies to help prevent severe RSV disease. Each dose is needed every 28–30 days, so you don’t want to skip or postpone any shots.
Your child should receive their first Synagis shot before the RSV season starts to help protect them before RSV becomes more active. If the season has already started, your child should receive their first Synagis shot as soon as possible to help protect them when exposure to the virus is more likely.

RSV season usually starts in the fall and continues into spring, but it can differ from place to place. Your doctor will tell you when RSV season has ended in your area.
Synagis is a prescription medication that is used to help prevent a serious lung disease caused by respiratory syncytial virus (RSV) in children at high risk for severe lung disease from RSV.
Children should not receive Synagis if they have ever had a severe allergic reaction to it. Signs and symptoms of a severe allergic reaction could include itchy rash; swelling of the face; difficulty swallowing; difficulty breathing; bluish color of the skin; muscle weakness or floppiness; a drop in blood pressure; and/or unresponsiveness. If your child has any of these signs or symptoms of a severe allergic reaction after getting Synagis, be sure to tell your child’s healthcare provider or get medical help right away.
Synagis is given as a shot, usually in the thigh muscle, each month during the RSV season. Your child should receive their first Synagis shot before the RSV season starts, to help protect them before RSV becomes active. When RSV is most active, your child will need to receive Synagis shots every 28-30 days to help protect them from severe RSV disease for about a month. Your child should continue to receive monthly shots of Synagis until the end of RSV season. Your child may still get severe RSV disease after receiving Synagis. If your child has an RSV infection, they should continue to get their monthly shots throughout the RSV season to help prevent severe disease from new RSV infections.
The effectiveness of Synagis shots given less than monthly throughout the RSV season has not been established.
Possible, serious side effects include severe allergic reaction, which may occur after any dose of Synagis. Such reactions may be life-threatening or cause death. Unusual bruising and/or groups of tiny red spots on the skin have also been reported.
Common side effects of Synagis include fever and rash. Other possible side effects include skin reactions around the area where the shot was given (like redness, swelling, warmth, or discomfort).
