If you have a new baby at home, or one on the way, somebody has probably already warned you about RSV. Your mother-in-law, a nurse friend, the lady behind you at Kroger. They mean well. But most of what gets passed around is a few years out of date. The good news is that protecting a baby from RSV is a lot easier now than it was in years past.
RSV stands for respiratory syncytial virus. For most people, it is just a cold. A runny nose, cough, and a few days of feeling unwell, and then it is gone. Nearly every child gets RSV by their second birthday.
The trouble is that babies have tiny airways called bronchioles. When RSV moves into the lungs, it can cause bronchiolitis, which is swelling and mucus in these airways. This same swelling in an adult wouldn’t be much of an issue, but in a baby, breathing can become quite difficult. That is why RSV is the leading reason babies under one end up hospitalized in the U.S., and why you hear so much about it every fall and winter.
Babies at higher risk include those born prematurely, those with heart or lung conditions, and anyone who is under six months of age during RSV season. But healthy, full-term babies end up in the hospital with RSV too. Most infants admitted each year have no risk factors.
Nationally, RSV season runs roughly October through March. In Georgia, it tends to show up in that same window, sometimes a little earlier once the weather turns. Once temperatures drop and kids head back into close, indoor spaces, RSV cases begin climbing.
A couple of seasons ago, the only real tools were hand washing and limiting contact with the outside world. Now there are two ways to protect against RSV.
This is often called "the RSV shot," though it is not a vaccine in the usual sense. A vaccine teaches your baby's body to build its own antibodies over time. This shot hands your baby ready-made antibodies, so protection starts right away and lasts through the whole season.
There are two options: nirsevimab (Beyfortus) and clesrovimab (Enflonsia). They work the same and are recommended by the American Academy of Pediatrics (AAP). Your baby gets a single injection in the thigh, and that is it. They can receive the vaccine at the same time as other vaccines.
Who should get it:
Vaccine side effects are usually mild, often involving a little redness or tenderness at the injection site. Both vaccines have been used in millions of babies, and studies show they cut RSV hospitalizations in infants by roughly 80% or more.
If you are pregnant, you can protect your baby before they are born. The RSV vaccine for pregnancy (Abrysvo) is given between 32 and 36 weeks and is offered seasonally from September through January so the timing lines up with RSV season.
With this option, mom’s body builds antibodies in response to the vaccine, and those antibodies cross the placenta to baby. Babies arrive already carrying protection through their first several months, which is exactly the window when RSV is most dangerous.
If you get the vaccine at least two weeks before delivery, your baby typically won’t need the antibody shot. If you deliver sooner than that, or you skip the vaccine, the antibody shot covers the gap. Either path gets your baby protected.
Most families do one or the other, not both. Neither is better, and it comes down to timing and what feels right for your family.
The shot and the vaccine do the heavy lifting for protecting against RSV, but the basics still help, especially in the first couple of months of your baby’s life.
RSV usually starts like a regular cold: runny nose, mild cough, maybe a low fever. Days three through five are typically the roughest, so keep a close eye on breathing then.
