Flu antivirals were significantly less likely to be prescribed to children hospitalized with the flu during the COVID-19 pandemic, a new study reveals. Honestly, it’s a bit unsettling—especially considering how quickly the flu can turn serious for kids.

Antiviral Use in Young Flu Patients Plummets

A recent study in Pediatrics shows a concerning drop in antiviral treatment for hospitalized children with influenza.

• Between December 2021 and March 2020, 48% to 57% of hospitalized children received antiviral medications for the flu.
• That number dropped to 38% in 2021-2022 and 46% in 2022-2023.
• Hospitalized children with underlying medical conditions, those vaccinated against the flu, and those tested for influenza were more likely to receive antivirals.
• Flu vaccination rates among hospitalized children also decreased during the pandemic, falling from 47% to 33%.

Why is this happening? Antiviral medications—like oseltamivir, peramivir, baloxavir, and zanamivir—can shorten the duration of flu symptoms and potentially reduce the risk of complications. The American Academy of Pediatrics recommends prompt treatment for hospitalized children, those with severe illness, or those at higher risk, even without a confirmed lab test.

Researchers from Vanderbilt University Medical Center analyzed data from 1,560 children hospitalized with influenza. The study, funded by the Centers for Disease Control and Prevention (CDC), found that children were more likely to receive antivirals if they had pre-existing health conditions, had been vaccinated against the flu, underwent clinical influenza testing, were admitted directly to the intensive care unit, or had experienced symptoms for two or more days before seeking medical attention.

Vaccination Rates Also Declined

The decline wasn’t limited to antivirals. The percentage of hospitalized children vaccinated against seasonal flu also decreased, dropping from 47% before the pandemic to 33% between July 1, 2021, and June 30, 2023.

The researchers didn’t pinpoint the exact reasons for the drop in antiviral use, but they suspect increased misinformation and a growing mistrust of the medical system played a role. They also suggest that both parents and healthcare providers might underestimate the severity of influenza in children.

“There’s a tendency to see the flu as a mild illness, but it can lead to serious complications—hospitalizations and even death—even in otherwise healthy children,” the researchers noted. It’s a reminder that influenza isn’t something to take lightly.
