United States: The United States is currently grappling with an exceptionally severe flu season, with cases soaring to levels unseen in recent years. Since October, influenza has infected an estimated 29 to 51 million people and led to as many as 820,000 hospitalizations.
This surge marks one of the most intense flu outbreaks in the past 15 years. Some experts suggest that “vaccination fatigue”—a lingering hesitancy stemming from prolonged debates over COVID-19—may be playing a significant role. Widespread misinformation and a general decline in public confidence toward vaccines could be discouraging people from getting their annual flu shots, leaving communities more vulnerable.
At the forefront of this outbreak is the influenza A virus, which differs from the viruses that cause the common cold. It appears to be exploiting gaps in immunity, spreading rapidly across the country, according to sciencealert.com.
Hospitals Under Strain as CDC Raises Alarm
According to recent estimates from the Centers for Disease Control and Prevention (CDC), the week of February 8 alone saw over 50,000 hospitalizations due to severe flu infections. Given the escalating case numbers, the CDC has classified this flu season as “high severity”—a designation last used during the 2017-2018 outbreak.
CDC spokesperson Paul Prince has urged anyone over six months old who has not yet received a flu shot this season to get vaccinated immediately. Health professionals emphasize that even at this late stage in the flu season, vaccination can still reduce transmission, lessen symptoms, and lower the risk of severe illness or complications.

While flu-related data is still evolving, preliminary CDC reports indicate that influenza deaths—especially from influenza A—are outpacing those linked to COVID-19. During the week ending February 8, flu was responsible for 2.6 percent of all deaths nationwide, including 68 pediatric fatalities.
A CDC heat map of respiratory illness in hospitals and outpatient clinics shows intense flu activity, with most states shaded in deep purple and red—indicating high infection rates. The only states reporting low flu levels are Montana, Alaska, and Hawaii, while Vermont has yet to provide sufficient data, as per sciencealert.com.
Why Are Flu Cases Skyrocketing?
While the precise cause of this flu season’s severity remains uncertain, multiple factors are likely contributing. For one, this year’s flu vaccine may be less effective than previous formulations. Additionally, flu vaccination rates have been steadily declining since the onset of the COVID-19 pandemic.
During the 2023-24 flu season, US vaccination rates hit their lowest point in over a decade. By the start of the 2024-25 flu season, only 37 percent of children had received their flu shots—a 6 percent drop from the previous year. Adults, too, are lagging in vaccination efforts. As of November 2024, only about 35 percent of US adults had been vaccinated against the flu, though many intended to do so later in the season.
Fast forward to February, and the data suggests that the majority of both children and adults in the US remain unvaccinated against this season’s flu strains.
Dispelling Misinformation: How the Flu Vaccine Works
Flu vaccines have been around for decades and remain one of the most effective tools in reducing the severity of influenza infections. However, false information continues to deter people from getting vaccinated, according to the reports by sciencealert.com.
Contrary to common myths, flu shots do not give people the flu. Instead, the vaccine primes the immune system to recognize and fight multiple strains of influenza. Though flu viruses constantly evolve, the vaccine significantly reduces the risk of severe illness, hospitalization, and death.
Serious side effects from flu shots—such as Guillain-Barré Syndrome—are extraordinarily rare, occurring in only one out of a million cases. Meanwhile, the flu vaccine helps prevent tens of thousands of deaths annually in the US and protects not just those who receive the shot but also those around them.
“Getting vaccinated may also safeguard vulnerable individuals, including infants, young children, the elderly, and those with chronic health conditions,” the CDC website states.
Rebuilding Trust in Vaccination
A 2022 study revealed that flu vaccinations lower the risk of severe, life-threatening influenza in children by 75 percent. Yet, vaccine hesitancy remains a growing challenge.
If the public is becoming fatigued by traditional vaccine messaging, health officials must rethink their approach. Communication strategies should emphasize clear, evidence-based information while also fostering trust through empathetic, non-judgmental conversations, as per the reports by sciencealert.com.
The American Academy of Family Physicians highlights the critical role that doctors and healthcare providers play in reversing declining vaccination rates. “By engaging in thoughtful discussions, addressing concerns with scientific facts, and sharing personal experiences, family physicians can help patients feel more confident about getting vaccinated.”
