3 Things to Know About the Respiratory Syncytial Virus (RSV)

Respiratory Syncytial Virus (RSV) is a virus that can cause respiratory infections in people of all ages. It can appear in the form of common cold symptoms for healthy adults. However, simple cold-like symptoms can escalate to more serious conditions for those with weaker immune systems.

RSV is especially concerning for infants less than one year old due to the high risk of contracting the virus. Don't worry. We have some helpful information so you can be proactive to keep your little ones safe.

1. Why is RSV Dangerous for Babies?

Infants need time to develop their immune system. After birth, they need time to adjust and build immunity against common infections. When infants contract RSV, they are more likely to experience serious complications, such as bronchiolitis or pneumonia. In severe cases, their symptoms can escalate and lead to hospitalization.

Symptoms of RSV infection may include:

  • Runny nose
  • Coughing
  • Sneezing
  • Fever
  • Wheezing or difficulty breathing

2. When is RSV season?

RSV occurs yearly during the fall season between October until spring. Peak RSV season occurs in December and January, but may vary each year.

People of all ages may contract and carry this virus, but infants and young children are most succeptible to the virus. Exposure to the respiratory virus primarily happens outside of family homes at childcare centers or schools. Adults ages 60 and older also have an increased risk of developing complications from this respiratory virus.

It's essential to be on guard during these months and take preventive measures to protect those with weaker immune systems.

3. Which Child Can Receive the RSV Vaccine?

Good news - there is now a vaccine to help shield babies from respiratory synctyial virus. Which babies are eligible for the vaccine? The CDC recommends RSV vaccination for the following children.

  • Infants less than 8 months old
  • Immunocompromised babies younger than 19 months old are eligible for the RSV vaccine.

Immunocompromised babies younger than 19 months will need two doses due to their weakened immune system. Administer the second RSV vaccine dose 28 days after receiving the first dose. Ensure your baby receives the full protection needed to face the RSV threat.

AgeNumber of Doses
<8 months1
Immunocompromised <19 months2


The respiratory syncytial virus vaccine is not a guarantee that your child will not get the infection. However, it is highly effective in reducing the severity of symptoms your infant may experience.

No kisses

Adults and young children should avoid kissing vulnerable infants that have not had the chance to build a strong immune system. This will prevent the chances of spreading viruses to infants.
