Understanding RSV

Respiratory syncytial virus (RSV) infects the lungs and airways. Its symptoms are usually similar to a cold, but it can become dangerous for infants, older adults, and those with weakened immune systems.

RSV Vaccines

RSV vaccines help prevent serious complications from the virus. The CDC recommends the RSV vaccine for everyone aged 75 and older and for people who are pregnant. Adults ages 60 to 74 who are at increased risk of severe RSV should also get vaccinated. That includes people who have a chronic illness such as heart disease or if you live in a nursing home.

How RSV Vaccines Work

The vaccines are single-dose, meaning you only need one shot to prevent illness. Unlike some vaccines that contain a small amount of a live virus, RSV vaccines only contain inactive proteins that help your body recognize and fight the virus. Because of this, you won’t get RSV from the shot.

Safety and Side Effects

Common side effects include pain at the injection site, headache, and fatigue. Muscle aches, joint pain, or tiredness may also occur. Serious side effects are rare but can include Guillain-Barré syndrome, a nervous system condition that causes muscle weakness or paralysis.

RSV Monoclonal Antibody for Infants

While there’s no RSV vaccine for children, they can receive a monoclonal antibody treatment. This treatment provides direct antibodies to help infants fight off RSV.
