RSV Prevention

How to Protect Yourself and Others

On October 23, 2023, CDC released a health advisory notice to communicate interim recommendations regarding the limited supply of nirsevimab, the new preventive antibody to protect infants against severe RSV.

RSV immunizations are recommended for these groups only:

  • Two RSV vaccines (Arexvy by GSK and Abrysvo by Pfizer) have been licensed by FDA and recommended by CDC for adults ages 60 and older, using shared clinical decision-making.
  • One RSV vaccine (Abrysvo by Pfizer) has been licensed and recommended during weeks 32 through 36 of pregnancy to protect infants.
  • An RSV preventive antibody has been licensed and recommended for infants and some young children.

Respiratory syncytial virus (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms. However, it can be dangerous for babies, toddlers, and older adults.

This year, CDC has recommended multiple, new immunizations to protect those most at risk of getting very sick with RSV: infants, toddlers, and adults 60 years and older.

For others who are less likely to get a severe RSV illness, everyday preventive actions can reduce the likelihood of spreading RSV.

New Immunizations to Protect Against Severe RSV

RSV Vaccine to Protect Adults Ages 60 and Older

RSV vaccines help protect adults 60 years and older from severe RSV illness. Older adults are at greater risk than young adults for serious complications from RSV because immune systems weaken with age. In addition, certain underlying medical conditions may increase the risk of getting very sick from RSV. Older adults with these conditions may especially benefit from getting RSV vaccine. If you are 60 years and older, talk to your healthcare provider to see if RSV vaccination is right for you.

RSV Immunizations to Protect Infants and Toddlers

There are two ways to protect your baby from getting very sick with RSV. One is an RSV vaccine given during pregnancy. The other is an RSV immunization that provides antibodies to your baby after birth. If you receive RSV vaccine while pregnant, your baby will have protection and, in most cases, should not need an RSV immunization later.

The two options to protect your baby are:

  1. Getting an RSV vaccine if you are 32-36 weeks pregnant during RSV season. This vaccine is recommended during September through January for most of the United States because RSV is typically a fall and winter virus. The seasonality of RSV season may vary depending on where you live, and state, local, or territorial health departments may recommend different timing for administration for their area.
  2. Getting an RSV antibody immunization for your baby if they are younger than 8 months and born during, or entering, their first RSV season. In rare cases, a healthcare provider may determine an RSV immunization is needed for an infant even though the mother received an RSV vaccine.

A dose of RSV antibody is also recommended for children between the ages of 8 and 19 months entering their second RSV season who are in at least one of these groups:

  • Children who have chronic lung disease from being born prematurely
  • Children who are severely immunocompromised
  • Children with cystic fibrosis who have severe disease
  • American Indian and Alaska Native children

Everyday Preventive Measures to Limit the Spread of RSV

You can take everyday prevention measures to help reduce the spread of RSV and other respiratory illnesses.

  • Stay home when sick.
  • Cover your coughs and sneezes with a tissue or your shirt sleeve, not your hands.
  • Wash your hands often with soap and water for at least 20 seconds.
  • Avoid touching your face with unwashed hands.
  • Avoid close contact with others, such as kissing, shaking hands, and sharing cups and eating utensils.
  • Clean frequently touched surfaces such as doorknobs and mobile devices.
