This year’s influenza shots indicate that hospitals significantly reduce seasonal influenza, as early data indicates.
For children and adolescents, the shots were at least 63 % of the influenza hospitals, up to 78 % in some areas. This is according to the data that was withdrawn from Two networks of healthcare centers The centers of control and prevention control (CDC) are monitored to assess the effectiveness of the influenza shot.
The “vaccine effectiveness” reflects the amount of chances of a specific health result in the real world, and is calculated by comparing the number of times that this result occurs in the people who have been vaccinated in exchange for non -fortified persons. So in this case, children who have been vaccinated have a 63 % less chance to 78 % to enter the influenza hospital.
For people between the ages of 18 years, the shots were 41 % and 55 % effective against the hospital, respectively, in two networks.

The bullets also reduced the possibility of outputs of the influenza, which include regular visits of the doctor, as well as urgent care and emergency department visits. For children and adolescents, the event level was 32 %, 59 % and 60 % in three networks, and for adults, it was 36 % and 54 % in two networks.
These estimates are shared Thursday (February 28) in A. The weekly report of the illness and deaths (MMWR), subject to change with the advance of the influenza season.
In a glance – Compared to the estimated estimates of the influenza shots last season At this time of last year-it seems that the 2024-2025 vaccines provide greater protection against hospitals for children. However, it may be less protection than outpatient visits to some children. On the other hand, adult protection appears slightly higher for both types of health care this season.
“The results in this report showed that vaccination with the influenza vaccine 2024-2025 reduced the possibility that the influenza that attends medically and support the recommendation of all people between the ages of 6 months against influenza.”
She concluded that “these results also support the strong preventive effect of vaccination on hospitals associated with influenza, which indicates the importance of vaccination to reduce complications related to the most severe influenza.”
MMWR authors suggested that a sub -type of influenza known as H3N2 explain the reason for the lack of preventive footage against children’s outpatient visits to children this season.
Human flu viruses Come in two wide types – Classification either “A” or “B” – which is then divided into sub -types and variables. CDC data appears The vast majority of influenza cases this year have occurred due to influenza viruses. The officials have a sub -group of these viruses and found that they were located in two sub -types: H1N1 and H3N2.
On the national level, both H1N1 and H3N2 are responsible for half of nearly half of the cases. However, the H1N1 ratio to H3N2 varies between regions, and therefore different networks. MMWR suggests that the shots were less protection against children’s outpatient clinics in areas where H3N2 was more prevalent. Laboratory experiences conducted with rodents He had already suggested that the shots were almost not good “matching” for H3N2 viruses as it was for H1N1 viruses.
However, influenza shots for this season show levels of protection “in line with those that take place from 2023-24 seasons and the seasons associated with the Gulf increase [vaccine efficacy] Over the past fifteen years, “MMWR says. The influenza season in the United States can run until May, so it is so It was not too late for influenza snapshot.
Influenza shots next season
Meanwhile, the fate of the next round of influenza-season 2025-2026-is unconfirmed.

It includes the production of influenza snapshot Increased viruses in chicken eggsThis takes time-usually there is a temporary store for a period of six months between the breeds of choosing the FDA (FDA) and the beginning of the vaccine vaccine in late July or early August, According to NBC. Delaying the choice of stress in the US market may mean that manufacturers do not have time to create enough vaccine for the start of the season, which can translate into higher rates of disease and death.
The cancellation of the FDA Consulting Committee follows Postpone a different meeting From the vaccine advisers to the Center for Disease Control. However, the Center for Disease Control and FDA recently participated in the World Health Organization meeting (WHO) on influenza shots, despite the Trump administration’s intention to withdraw from the World Health Organization, Stat was reported.
The World Health Organization meeting usually directs the choice of food and drug management strain in the United States market, although the agency can choose to choose American vaccines if it chooses.
