While RSV is typically just a cold for most people, it can pose a serious threat to infants. Fortunately, there is now a vaccine that offers protection to babies. The CDC’s advisory panel has recommended that all infants under 8 months of age receive the vaccine at the start of RSV season (typically in the fall, similar to flu shots). Here’s everything you need to know about this new vaccine.
What exactly is RSV?
RSV, or respiratory syncytial virus, causes symptoms similar to a cold, such as a runny nose, coughing, and sneezing. For most people, that's all there is to it—you may have had RSV without even realizing it.
The virus, however, can be deadly for older adults and individuals with weakened immune systems. It’s also particularly risky for babies, especially preterm infants and those under six months of age. (This past winter, we saw a rise in RSV cases, and you can find more details about the virus and its surge here.)
What exactly is this new RSV vaccine for babies?
The new RSV vaccine for babies is a monoclonal antibody called nirsevimab (brand name Beyfortus), which offers protection for several months. Unlike most vaccines that stimulate the body to produce antibodies, this one directly delivers the antibodies to the baby.
This is the first 'passive' vaccine included in the childhood vaccine schedule (passive immunity means the baby’s immune system doesn't have to respond). Babies naturally receive passive immunity through antibodies from breastfeeding and placental blood before birth. While it's not a new concept for babies to get antibodies in this way, this is the first time it's being given routinely as a vaccine.
Antibodies tend to be pricier than most vaccines, but those on the standard childhood vaccine schedule must be covered by insurance plans. If your child is uninsured or if their insurance doesn’t cover vaccines, they can still receive their vaccines (including RSV) for free through the government’s Vaccines for Children program. This program also offers free vaccines for children eligible for Medicaid or who are American Indian or Alaskan Native.
CNN reports that insurers will pay $495 for the vaccine, with the Vaccines for Children program offering a reduced price of $395. Parents will incur no out-of-pocket expenses for this vaccine.
Who is eligible for the new infant RSV vaccine?
The vaccine is recommended for all children under 8 months old, particularly those born during RSV season or those who will still be under 8 months old when RSV season begins. This season typically spans from October to March, although it can vary depending on the year and location. The vaccine is expected to be ready for this RSV season.
Children between 8 and 19 months may need a dose of the vaccine the following year if they are at high risk for complications, such as those with severe immunocompromised conditions.
Earlier this year, two RSV vaccines for adults over 60 were approved. The CDC highlighted that adults with chronic heart or lung conditions, weakened immune systems, or those residing in nursing homes or long-term care facilities might consider receiving the vaccine.
