As respiratory virus season gets underway, new research reinforces the importance of influenza vaccination in long-term and senior care settings. 

A recent study examining acute respiratory infections among nursing home residents found that influenza remains a significant contributor to respiratory illness and complications. 

Researchers followed 3,195 residents across 15 nursing homes between March 2023 and May 2025. Among respiratory infection episodes in which a virus was identified, influenza A accounted for 23.6% of cases, second only to SARS-CoV-2 at 29%. 

The study also found that influenza A was associated with delayed recovery, increased oxygen requirements, and a greater risk of secondary bacterial pneumonia. 

A Timely Reminder for Flu Season 

These findings underscore why influenza deserves continued attention as part of respiratory illness management, particularly among older adults and those with underlying health conditions. 

The CDC recommends annual influenza vaccination for everyone six months and older, with rare exceptions. Vaccination is especially important for adults 65 and older, who face an increased risk of serious flu-related complications. 

For long-term and senior care providers, now is a good time to: 

• Review resident vaccination status. Identify residents who have not yet received their seasonal influenza vaccine and address outstanding vaccinations as appropriate. 
• Encourage staff vaccination. Remind team members who have not been vaccinated of the importance of protecting themselves and those in their care. 
• Communicate with residents and families. Reinforce the benefits of annual influenza vaccination and address questions or concerns. 
• Maintain infection prevention practices. Continue respiratory illness surveillance, timely identification of symptoms, and appropriate infection prevention measures. 

 Don't Let the Flu Shot Fall Off the Priority List 

The CDC recommends receiving the seasonal influenza vaccine ideally by the end of October. However, vaccination should continue throughout the flu season, as long as influenza viruses are circulating. 

For providers still completing resident vaccinations—and individuals who have not yet received their own flu shot—now is the time to make it a priority.
