As flu season peaks, a new study conducted by Spanish researchers reinforces the critical role of vaccination in mitigating the potentially severe consequences of the flu. Analyzing data from over 192,000 patients across multiple flu seasons, the researchers found that while the vaccine doesn’t always prevent infection, it significantly reduces the severity of illness in those who receive it.
“It is essential to reinforce vaccination and communicate to the public the importance of preventing flu,” states José María Eiros, director of the National Center for the Flu in Valladolid, Chief of Microbiology Service at the Hortega de Valladolid University Hospital, and co-author of the study. “This preventative measure is crucial not only to avoid infection but also to reduce serious complications.”
Influenza, caused by four types of viruses, poses a continuous challenge to global health systems.
As Eiros explains, “The flu has a significant impact on health for two main reasons: first, its seasonality, with a surge in cases every winter lasting between 12 and 16 weeks. Second, the disease puts a considerable strain on healthcare resources, leading to increased demand in emergency rooms, hospitalizations, and, in some cases, intensive care unit admissions.”
Although the incidence of flu fluctuates yearly, its potential to cause severe complications, particularly in vulnerable populations, makes it a priority for public health surveillance.
Estanislao Nistal, stresses that while the flu vaccine isn’t foolproof and its effectiveness fluctuates yearly, ranging from 30% to 60% depending on the season, its impact in reducing the overall burden of flu and protecting against death is undeniable.”We’re not revealing something new, but we are quantifying the impact of flu vaccination on death prevention over two decades,” says nistal.
Dr. José María Eiros, director of the National Center for the Flu of Valladolid and a leader in the research, echoes this sentiment. “even though the vaccine has limitations, it remains the best tool we certainly know to prevent flu and, above all, avoid serious complications.” This study, involving a meta-analysis of 192,705 patient records and an even broader examination of six million individuals across 40 nations, delves into the vaccine’s capacity to combat complications across different age groups and virus variants.The findings are compelling.Vaccination not only reduces hospitalization rates but also significantly lowers the risk of life-threatening complications like pneumonia and respiratory failure, notably for individuals with chronic illnesses, compromised immune systems, or advanced age. As Eiros emphasizes, “The impact of the flu should never be underestimated. Complications can be very serious.”
While protecting older adults from flu complications is widely recognized as essential,the study also highlights the importance of vaccination for younger populations. It analyzed the impact of vaccination on three key age groups: under five years of age, individuals between five and 65, and those over 65.Eiros points out that there is mounting evidence supporting the need for extensive flu vaccination strategies across all age brackets.
Flu Vaccine: more Than Just infection Prevention
Seasonal influenza, or the flu, is a serious illness that can lead to hospitalization and even death, particularly in vulnerable populations.While the flu vaccine doesn’t always prevent infection, its importance in mitigating the severity of the disease and reducing mortality cannot be overstated.
A recent study underscores this crucial point, emphasizing that the effectiveness of the flu vaccine goes beyond simply preventing infection and focuses on reducing the risk of serious complications and death.
“It is importent to clarify that the effectiveness is not only measured in avoiding infection, but that the disease is not so severe and, above all, in which mortality decreases,” explains Estanislao Nistal, principal researcher of the virology and Innate Immunity Group at the CEU San Pablo University.
This finding is especially relevant considering the common perception that the flu vaccine is not very effective. While the vaccine’s effectiveness against infection can fluctuate due to the constantly evolving virus, it consistently provides robust protection against severe illness and death.experts highlight the need to shift the focus from solely preventing infection to recognizing the vaccine’s vital role in reducing the impact of the flu.
“We carry out a systematic review and a meta-analysis that allows validating the effectiveness of vaccination and its impact on the reduction of complications,” explains researcher Eiros.
The study identifies that the flu vaccine’s effectiveness in reducing mortality is particularly pronounced in high-risk groups, such as those with cardiovascular diseases and degenerative diseases.
“If a person with hypertension or a cardiac pathology had a 100% probability of dying because of the flu, with the vaccine that probability would be reduced to 25%,” Nistal exemplifies.Vaccination in these individuals can decrease the risk of death by three to four times.

Flu vaccine: A Behind-the-Scenes look With Dr. Anya Sharma
Flu season is here, and with it comes the usual questions about the effectiveness of the flu vaccine. To cut through the confusion and address public concerns, we sat down with Dr. Anya Sharma, a leading virologist at the National Center for Infectious Diseases.
Archyde News: Dr.Sharma, can you explain how the flu vaccine works and why it’s crucial to get vaccinated every year?
dr. Sharma: The flu vaccine contains weakened or inactive parts of the influenza virus. When you get vaccinated,your body recognizes these pieces as invaders and builds an immune response. Think of it as your body’s training program for fighting off the real flu virus if you encounter it. Because flu viruses are constantly changing, we need to update the vaccine every year to target the strains that are most likely to circulate.
Archyde News: We often hear that the flu vaccine isn’t always effective. Can you clarify this for us?
Dr. Sharma: You’re right, it’s not a perfect shield. The effectiveness of the vaccine can vary depending on factors like the age and health of the individual, and also how well the vaccine matches the circulating strains that year. It’s significant to remember that the vaccine’s main goal is to prevent severe illness, hospitalization, and death, even if it doesn’t fully prevent infection.
Think of it like a seatbelt.A seatbelt doesn’t guarantee you won’t get injured in a car accident, but it dramatically reduces the severity of potential injuries.
Why Flu Shots Still Matter: A Conversation with Dr. Sharma
Getting sick with the flu can be a miserable experience. But what if there was a way to significantly reduce your chances of getting seriously ill? Enter the flu shot, a simple and effective tool that offers crucial protection.
“It’s true that the flu vaccine doesn’t always prevent infection completely,” explains Dr.Sharma, “but it’s incredibly effective at reducing the severity of illness if you do get sick.”
Dr. Sharma emphasizes that even if you contract the flu after vaccination, the benefits are still considerable. “The vaccine acts like a safety net,protecting you from the worst outcomes of the flu,” he says. This is particularly critically important for vulnerable populations like young children, pregnant women, older adults, and those with chronic health conditions.
“Getting vaccinated is the single best way to protect yourself and your loved ones from the flu.It’s a simple, safe, and effective way to significantly reduce your risk of serious illness and contribute to a healthier community,” Dr. Sharma stresses, underscoring the importance of this preventive measure.
