Respiratory Season 2025: What Communities and Agencies Need to Know

Five years into the COVID-19 era, respiratory season has taken on a different weight. What was once a predictable winter rhythm — flu shots, hand-washing reminders, the occasional outbreak — now means managing two simultaneous viral threats against a backdrop of deep public fatigue. The 2025-26 season presents challenges that are by now familiar but no less urgent: waning population immunity, updated vaccine formulations for both COVID-19 and influenza, and a public that is more skeptical of public health messaging than at any point in recent memory.

The dual-threat landscape

COVID-19 variants continue to evolve, and this season's predominant strains have once again outpaced earlier vaccine formulations. Updated boosters are available, as are reformulated influenza vaccines targeting the strains most likely to circulate this winter. The good news is that the science continues to advance. The harder truth is that uptake remains uneven. Hospitalization data from last season confirmed what equity-focused researchers have documented for years: older adults, immunocompromised individuals, and communities of color continue to bear a disproportionate burden. Black and Latino adults were hospitalized at significantly higher rates than white adults for both COVID-19 and influenza, and mortality disparities persisted across age groups. These are not new findings, but they demand renewed attention every season because the consequences are measured in lives.

Communication fatigue is real

Perhaps the greatest obstacle facing public health agencies this season is not the virus itself but the challenge of reaching communities that have tuned out. Five years of emergency messaging, shifting guidance, and politicized discourse have taken a measurable toll. Research on message fatigue shows that repeated health communications lose effectiveness over time, particularly when audiences perceive inconsistency or feel that messaging does not reflect their lived experience. Trust in public health institutions has declined across nearly every demographic, but the erosion is steepest in the communities that need accurate information most. Evidence from behavioral science suggests that in low-trust environments, the messenger matters more than the message. Credibility is built through relationship, not repetition.

What works: lessons from the field

The most effective respiratory season campaigns over the past three years share common features. They rely on trusted messengers — community health workers, faith leaders, local clinic providers, and neighborhood advocates — rather than institutional spokespeople. They use culturally and linguistically tailored materials developed with community input, not simply translated from English. And they meet people where they already are: pharmacies, schools, community centers, and places of worship. Programs that embedded vaccine access into existing community touchpoints consistently outperformed traditional clinic-based campaigns, particularly in reaching uninsured and undocumented populations.

Guidance for agencies

For public health agencies planning fall and winter outreach, the evidence points toward several practical priorities. Invest in sustained community engagement rather than one-time campaigns that spike around October and fade by December. Fund and support trusted messenger networks year-round so that relationships are already in place when respiratory season arrives. Co-design materials with the communities you intend to serve. Make access as frictionless as possible — mobile clinics, extended pharmacy hours, and no-cost options reduce the barriers that disproportionately affect low-income residents. Finally, communicate with honesty about what vaccines can and cannot do. Overpromising erodes the very trust you are trying to rebuild.

Respiratory season is no longer a single-threat event, and our response strategies cannot be either. Equity-centered, community-driven approaches are not aspirational — they are the baseline for effective public health practice.
