This is the current release of the guideline.

American Academy of Pediatrics (AAP) Policies are reviewed every 3 years by the authoring body, at which time a recommendation is made that the policy be retired, revised, or reaffirmed without change. Until the Board of Directors approves a revision or reaffirmation, or retires a statement, the current policy remains in effect.

1. Palivizumab or Respiratory Syncytial Virus Immune Globulin Intravenous (RSV-IGIV) prophylaxis should be considered for infants and children younger than 2 years of age with chronic lung disease (CLD) who have required medical therapy (supplemental oxygen, bronchodilator, diuretic, or corticosteroid therapy) for CLD within 6 months before the anticipated start of the respiratory syncytial virus (RSV) season. Palivizumab is preferred over RSV-IGIV for most high-risk children because of its ease of administration, safety, and effectiveness. (Evidence grade I)
   • Patients with more severe CLD may benefit from prophylaxis during a second RSV season if they continue to require medical therapy for pulmonary or cardiac dysfunction. Individual patients may benefit from decisions made in consultation with neonatologists, pediatric intensivists, pulmonologists, or infectious disease specialists. There are limited data regarding the effectiveness of palivizumab during the second year of life, although children with CLD or congenital heart disease (CHD) who require ongoing medical therapy may experience severe RSV infections.
2. Infants born at 32 weeks’ gestation or earlier may benefit from RSV prophylaxis, even if they do not have CLD. For these infants, major risk factors to consider include their gestational age and chronologic age at the start of the RSV season. (Evidence grade I)
   • Infants born at 28 weeks’ gestation or earlier may benefit from prophylaxis during their first RSV season whenever that occurs during the first 12 months of life. Infants born at 29 to 32 weeks’ gestation may benefit most from prophylaxis up to 6 months of age. For the purpose of this recommendation, 32 weeks’ gestation refers to an infant born on or before the 32nd week of gestation (i.e., 32 weeks, 0 days). Once a child qualifies for initiation of prophylaxis at the start of the RSV season, administration should continue throughout the season and not stop at the point an infant reaches either 6 months or 12 months of age.
3. Although palivizumab and RSV-IGIV have been shown to decrease the likelihood of hospitalization for infants born between 32 and 35 weeks of gestation (i.e., between 32 weeks, 1 day and 35 weeks, 0 days) (Evidence grade I), the cost of administering prophylaxis to this large group of infants must be considered carefully.
   • Most experts recommend that prophylaxis be reserved for infants in this group who are at greatest risk of severe infection and who are younger than 6 months at the start of the RSV season. Epidemiologic data suggest that RSV infection is more likely to lead to hospitalization for these infants when the following risk factors are present: child care attendance, school-aged siblings, exposure to environmental air pollutants, congenital abnormalities of the airways, or severe neuromuscular disease. However, no single risk factor causes a very large increase in the rate of hospitalization, and the risk is additive as the number of risk factors for an individual infant increases. Therefore, prophylaxis should be considered for infants between 32 and 35 weeks’ gestation only if 2 or more of these risk factors are present.
   • Exposure to tobacco smoke is a risk factor that can be controlled by the family of an infant at increased risk of RSV disease, and tobacco smoke control measures will be far less costly than palivizumab prophylaxis. High-risk infants never should be exposed to tobacco smoke. High-risk infants should be kept away from crowds and from situations where exposure to infected individuals cannot be controlled.
   • Participation in child care should be restricted during the RSV season for high-risk infants whenever feasible. Parents should be instructed on the importance of careful hand hygiene.
   • All high-risk infants and their contacts should be immunized against influenza beginning at 6 months of age.
4. Prophylaxis against RSV should be initiated just before the onset of the RSV season and terminated at the end of the RSV season. In most seasons and in most regions of the Northern Hemisphere, the first dose of palivizumab should be administered at the beginning of November and the last dose should be administered at the beginning of March, which will provide protection into April. (Evidence grade III)
   • To understand the epidemiology of RSV in their area, physicians should consult with local health departments or diagnostic virology laboratories or the Centers for Disease Control and Prevention if such information is not available locally. Decisions about the specific duration of prophylaxis should be individualized according to the duration of the RSV season. Pediatricians may wish to use RSV hospitalization data from their own region to assist in the decision-making process.
5. Children who are 24 months of age or younger with hemodynamically significant cyanotic and acyanotic CHD will benefit from 5 monthly intramuscular injections of palivizumab (15 mg/kg). (Evidence grade I)
   • Decisions regarding prophylaxis with palivizumab in children with CHD should be made on the basis of the degree of physiologic cardiovascular compromise. Infants younger than 12 months with CHD who are most likely to benefit from immunoprophylaxis include:
     1. Infants who are receiving medication to control congestive heart failure (CHF)
     2. Infants with moderate to severe pulmonary hypertension
     3. Infants with cyanotic heart disease
   • Because a mean decrease in palivizumab serum concentration of 58% was observed after surgical procedures that use cardiopulmonary bypass, for children who still require prophylaxis, a postoperative dose of palivizumab (15 mg/kg) should be considered as soon as the patient is medically stable.

   The following groups of infants are not at increased risk from RSV and generally should not receive immunoprophylaxis:

   • Infants and children with hemodynamically insignificant heart disease (e.g., secundum atrial septal defect, small ventricular septal defect, pulmonic stenosis, uncomplicated aortic stenosis, mild coarctation of the aorta, and patent ductus arteriosus)
   • Infants with lesions adequately corrected by surgery unless they continue to require medication for congestive heart failure
   • Infants with mild cardiomyopathy who are not receiving medical therapy

   Dates for initiation and termination of prophylaxis should be based on the same considerations as for high-risk preterm infants. Unlike palivizumab, RSV-IGIV is contraindicated in children with cyanotic CHD.

6. Palivizumab or RSV-IGIV prophylaxis has not been evaluated in randomized trials in immunocompromised children. Although specific recommendations for immunocompromised patients cannot be made, children with severe immunodeficiencies (e.g., severe combined immunodeficiency or severe acquired immunodeficiency syndrome) may benefit from prophylaxis. If these infants and children are receiving standard IGIV monthly, physicians may consider substitution of RSV-IGIV during the RSV season. (Evidence grade III)
7. Because RSV-IGIV and palivizumab are not effective in the treatment of RSV disease, neither is licensed for this indication. (Evidence grade I)
8. Limited studies suggest that some patients with cystic fibrosis may be at increased risk of RSV infection. However, there are insufficient data to determine the effectiveness of palivizumab use in this patient population.
9. If an infant or child who is receiving immunoprophylaxis experiences a breakthrough RSV infection, prophylaxis should continue through the RSV season. (Evidence grade III)
   • This recommendation is based on the observation that high-risk infants may be hospitalized more than once in the same season with RSV lower respiratory tract disease and the fact that more than one RSV strain often co-circulates in a community.
10. Physicians should arrange for drug administration within 6 hours after opening a vial, because this product does not contain a preservative.
11. Recommendations cannot be made regarding the use of palivizumab as a means of prevention of nosocomial RSV disease.
    • RSV is known to be transmitted in the hospital setting and to cause serious disease in high-risk infants. In high-risk hospitalized infants, the major means to prevent RSV disease is strict observance of infection control practices, including the use of rapid means to identify and isolate RSV-infected infants. If an RSV outbreak is documented in a high-risk unit (e.g., pediatric intensive care unit [ICU]), primary emphasis should be placed on proper infection control practices, especially hand hygiene.

12. Palivizumab does not interfere with the response to vaccines. Infants and children receiving prophylaxis with RSV-IGIV should have immunization with measles-mumps-rubella and varicella vaccines deferred for 9 months after the last dose of RSV-IGIV.
    • The use of RSV-IGIV should not alter primary immunization schedule for other recommended immunizations. Available data at this time do not support the need for supplemental doses of any of these routinely administered vaccines.
