As temperatures begin to fall across the United States, seasonal respiratory viruses become an important health concern. For the 2026–27 season, updated guidance on flu, COVID-19 and RSV vaccines can help families prepare before respiratory illnesses become more widespread.
The Centers for Disease Control and Prevention (CDC) says staying current with recommended immunizations can reduce the risk of hospitalization and severe respiratory illness. The right vaccine schedule, however, depends on age, health conditions, pregnancy status and other individual factors.
What Is New About the 2026–27 Flu Vaccine?
The 2026–27 U.S. flu vaccines have been updated compared with the previous season. The CDC reports that all three virus components were changed, including an update targeting an influenza A(H3N2) subclade that circulated widely during the previous season.
Flu vaccination is recommended annually for people aged 6 months and older. For most people who need only one dose, September or October is generally the preferred vaccination period. Getting vaccinated too early may reduce protection later in the season, so timing can matter.
What About COVID-19 Vaccination?
COVID-19 vaccination remains part of seasonal respiratory-virus prevention. Current CDC guidance recommends discussing vaccination with a healthcare professional, particularly because recommendations can vary according to age and individual risk.
People who are moderately or severely immunocompromised have specific COVID-19 vaccination guidance. They should discuss the appropriate schedule with their healthcare provider.
Who Should Consider an RSV Vaccine?
RSV vaccination is different from flu vaccination because it is not currently an annual vaccine. CDC guidance recommends RSV vaccination for adults aged 75 and older and for adults ages 50–74 who have an increased risk of severe RSV illness.
The CDC says eligible adults can receive the RSV vaccine at any time, although late summer and early fall are considered the best timing before RSV typically begins spreading more widely.
Can You Get Flu, COVID and RSV Vaccines Together?
Yes. Eligible people can receive flu, COVID-19 and RSV vaccines during the same visit. There is also no required waiting period between these vaccines when they are administered during separate visits.
Receiving multiple vaccines at one appointment can be convenient, especially for people who have difficulty making several healthcare visits. However, individuals should discuss their personal vaccination needs with a doctor or pharmacist.
What Should You Do This Fall?
Start by reviewing your vaccination history and determining which vaccines you are due to receive. Older adults, pregnant people, young children and individuals with certain medical conditions may have different recommendations.
It is also important to remember that vaccination is only one part of respiratory-virus prevention. Staying home when sick, improving indoor ventilation and practicing good hygiene can also help reduce transmission.
The 2026–27 fall respiratory-virus season brings updated flu vaccine formulations and continuing guidance for COVID-19 and RSV protection. Check your eligibility with a healthcare professional and plan ahead rather than waiting until respiratory viruses are already circulating widely.
