RSV recommendations unchanged after review of new data :

October 19, 2017

In the Northern Hemisphere, the autumnal equinox marks the first day of autumn. This is a time when the sun is directly over the equator so that the length of night and day is almost equal. For pediatricians, it also is a time to anticipate the upcoming respiratory virus season and to educate families on the importance of handwashing, respiratory etiquette and influenza vaccination.

All children 6 months of age or older should receive age-appropriate influenza immunizations. For infants and young children at increased risk of respiratory syncytial virus (RSV) infection, monthly prophylaxis with palivizumab may be considered.

In August 2014, the Academy published the most recent guidelines to assist with identification of young children at increased risk of RSV hospitalization and most likely to benefit from prophylaxis. For a complete discussion of the basis for each recommendation, see the AAP policy statement (Pediatrics. 2014;134:415-420, and technical report (Pediatrics. 2014;134:e620-e638,, both titled Updated Guidance for Palivizumab Prophylaxis Among Infants and Young Children at Increased Risk of Hospitalization for Respiratory Syncytial Virus Infection and Clinical Practice Guideline: The Diagnosis, Management and Prevention of Bronchiolitis (Pediatrics. 2014;134:e1474-e1502,

Following recent reviews by the Committee on Infectious Diseases and the Subcommittee on Bronchiolitis, these recommendations remain unchanged from 2014. A summary of current recommendations is presented here.

  • In the first year of life, palivizumab prophylaxis is recommended for infants born before 29 weeks, 0 days’ gestation.
  • Palivizumab prophylaxis is not recommended for otherwise healthy infants born at or after 29 weeks, 0 days’ gestation.
  • In the first year of life, palivizumab prophylaxis is recommended for preterm infants born before 32 weeks, 0 days’ gestation with chronic lung disease of prematurity defined as a need for greater than 21% oxygen for at least 28 days after birth.
  • Clinicians may administer palivizumab prophylaxis in the first year of life to certain infants with hemodynamically significant heart disease. Consultation with a cardiologist for decisions about prophylaxis is recommended for patients with cyanotic heart disease.
  • For qualifying infants who require five doses, a dose beginning in November and continuing for a total of five monthly doses will provide protection for most infants through April and is recommended for most areas in the U.S.
  • Clinicians may administer up to a maximum of five monthly doses of palivizumab during the RSV season to infants who qualify for prophylaxis in the first year of life (including those in Florida). Qualifying infants born during the RSV season will require fewer doses. For example, infants born in January would receive their last dose in March.
  • Palivizumab prophylaxis is not recommended in the second year of life except for children who require at least 28 days of supplemental oxygen after birth and who continue to require medical intervention (supplemental oxygen, chronic corticosteroid or diuretic therapy) during the second RSV season.
  • Monthly prophylaxis should be discontinued in any child who experiences an outpatient RSV infection or breakthrough RSV hospitalization.
  • Children with a pulmonary abnormality or neuromuscular disease that impairs the ability to clear secretions from the lower airways may be considered for prophylaxis in the first year of life.
  • Children younger than 24 months of age who will be profoundly immunocompromised during the RSV season may be considered for prophylaxis.
  • Insufficient data are available to recommend palivizumab prophylaxis routinely for children with cystic fibrosis or Down syndrome.
  • The burden of RSV disease in certain remote areas may result in a broader use of palivizumab for RSV prevention in Alaska Native populations and possibly in other selected Native American populations.
  • Palivizumab prophylaxis is not recommended for prevention of nosocomial acquired RSV disease.

Detailed input regarding current guidelines was solicited from 21 AAP committees, councils, sections and advisory groups as well as from organizations outside the Academy. Outside groups that contributed to and concur with the updated guidance include the American Academy of Family Physicians, American College of Chest Physicians, American College of Emergency Physicians, Emergency Nurses Association, and Society of Hospital Medicine.

The Committee on Infectious Diseases and the Subcommittee on Bronchiolitis regularly review and evaluate all data and as they become available. In September 2017, all available data regarding palivizumab were considered, and both groups reaffirmed the recommendations in the RSV policy statement and technical report.
