Infant Respiratory Infections: $52M Study on Lung Health

Key points at a glance

• A Michigan Medicine-led consortium has received approval for up to $52 million in federal funding for a multicenter study of infant respiratory infections.
• The SPIN VINYL study aims to enroll 1,500 hospitalized children aged 0–24 months and follow them until at least age four to five.
• Researchers will investigate immune responses, viral characteristics, airway microbiomes, and environmental exposures that may influence recovery and long-term respiratory health.
• Findings could help clinicians identify children at risk of recurrent wheezing, asthma and persistent lung problems after early-life infections.

Infant Respiratory Infections: $52M Study to Investigate Long-Term Lung Health

A new research initiative aims to help clinicians understand why some infants recover completely from severe respiratory infections while others develop persistent lung problems. A consortium led by Michigan Medicine has secured approval for up to $52 million in federal funding for a multicenter study examining the biological and environmental factors that shape respiratory health after early-life infections.

The study, called Systematic Phenotyping and Endotyping in Viral Infections in the Young Lung (SPIN VINYL), will investigate how young children respond to viral lower respiratory tract infections and why their long-term outcomes can differ.

Why Do Some Infants Develop Lasting Respiratory Problems?

Viral lower respiratory tract infections, including bronchiolitis, pneumonia, and pediatric acute respiratory distress syndrome (ARDS), are major causes of hospitalization in infants and toddlers. Early-life infections have also been associated with recurrent wheezing, asthma, and other respiratory complications.

However, clinicians currently have limited tools to predict which hospitalized children will recover fully and which may experience ongoing respiratory problems.

The SPIN VINYL study aims to address this gap by enrolling 1,500 children aged 0–24 months across 10 hospitals in the United States. Researchers will follow participants until at least ages four to five to examine their recovery and longer-term lung health.

Peter Mourani, M.D., principal investigator and pediatric critical care specialist at Michigan Medicine and U-M Health C.S. Mott Children’s Hospital, said the study will examine different recovery patterns and help identify when clinicians might intervene.

How Will the SPIN VINYL Study Investigate Infant Lung Health?

Researchers will combine clinical assessments with lung function testing, imaging, environmental exposure measurements, activity and sleep monitoring, and advanced molecular analyses.

The team will investigate several factors that could influence respiratory outcomes:

• Immune responses: How a child’s immune system responds to viral infection.
• Viral characteristics: How differences among infecting pathogens relate to disease severity and recovery.
• Airway microbiome: How microorganisms in the airways may influence respiratory health.
• Environmental exposures: How factors such as air pollution and tobacco smoke may affect recovery.

Researchers will integrate these findings using advanced statistical methods, informatics, machine learning, and artificial intelligence to identify patterns linked to different disease trajectories.

What Could the Findings Mean for Pediatric Respiratory Care?

The researchers hope to identify measurable biological signatures that could help clinicians recognize children at greater risk of persistent respiratory disease. The study will also examine outcomes among vulnerable groups, including children born preterm and those with congenital heart disease.

The National Heart, Lung, and Blood Institute (NHLBI) has approved the project’s first year of funding. Michigan Medicine will serve as the clinical coordinating center, working with nine additional hospitals across the country.

By combining clinical information, biological data, and environmental measurements, SPIN VINYL could provide a clearer understanding of why children respond differently to similar infections. In the future, these findings may inform risk assessment, targeted monitoring and preventive strategies for infants recovering from severe viral respiratory illness.

For pediatricians, pulmonologists, nurses, and critical care teams, better evidence about long-term outcomes could support more informed follow-up care and help identify children who may need closer respiratory monitoring after hospitalization.
