In autumn and winter, acute respiratory infections, such as influenza, entered the high season. Influenza (known as influenza) is an acute respiratory epidemic caused by influenza viruses that poses serious risks to human health. Influenza is highly contagious and can lead to a number of serious complications, including pneumonia and myocarditis, and annual influenza vaccinations are an economically effective response to influenza。

We've got nine core issues of concern
With a clear question and answer
I'll give you a quick update on the flu vaccine
It's a healthy and safe flu season
Q: why was the flu vaccine last year and this year
The first one is the flu virus's “changeful”. Influenza viruses vary rapidly and the strains of the epidemic may vary from year to year, the world health organization recommends a new year's influenza vaccine each year based on global monitoring data, and the vaccine component is adjusted and updated every year。
The second is the length of protection of the influenza vaccine. Protective antibodies produced after vaccination are usually only maintained for six to eight months. In order to prevent the current epidemic more precisely, annual “up-to-date” vaccinations are the way to sustain effective protection。
Q: what are the types of influenza vaccine
Response: the influenza vaccine currently approved for listing includes the trivalent influenza vaccine and the trivalent influenza vaccine, whose “price” refers mainly to vaccine-preventable influenza virus types such as h1n1, h3n2 and the victoria virus。
In terms of production, the influenza vaccine is divided into live vaccine and detoxification vaccine, which can be used for people aged 6 and above, by internal injection, and by nasal spray for people aged 3 to 17。
Q: when will the flu be vaccinated
Response: september-october is a gold vaccination period, usually two to four weeks after vaccinations produce antibodies with a protective level that will ensure that immunization barriers are in place before influenza peaks. However, if missed, immunization is protected at any time throughout the influenza season。
Q: which groups recommended priority vaccination against influenza
Response: inoculation against influenza can significantly reduce the risk of infection and serious complications. It is recommended that those aged 6 and above who are not vaccinated should be vaccinated. In order to minimize the risk of influenza, priority is given to the following priority and high-risk populations:
1 medical personnel
2-60-year-olds
Persons suffering from chronic diseases such as cardiovascular diseases (except for pure hypertension), chronic respiratory diseases, incomplete liver and kidney function, blood diseases, nervous system diseases, neuromuscular disorders, metabolic diseases (including diabetes), immunosuppressive diseases or low immune function
Residents and employees of pension institutions, long-term care institutions, welfare homes, etc.
5 pregnant women
Children aged 66-59 months
Family members and carers of infants under 76 months of age
8 priority groups in childcare institutions, primary and secondary schools, places of custody, etc。
Q: are you allergic to eggs and can you get flu vaccine
A: yes! Don't worry. Neither our current pharmacist nor the who position paper uses egg allergies as a taboo. Currently, some of the country's influenza vaccine product instructions do not include egg allergies as a taboo, and the chinese technical guidelines for inoculation against influenza (2025-2026) recommends that egg allergies not be classified as a taboo influenza vaccine in the egg allergy certificate。
Q: can flu vaccines be administered at the same time as other vaccines
Response: yes! Inoculation of influenza and other active vaccines or detoxification vaccines can be carried out simultaneously in different areas, such as pneumocococcal vaccine, herpes vaccine, pox vaccine, mumps vaccine, white-and-white vaccine, etc., while being easily and efficiently administered. Vaccination against influenza is subject to an interval of more than four weeks in order to be able to obtain another dose。
Q: does this year's flu vaccine work for h3n2? Choose trivalent or tetravalent influenza vaccine
Response: the trivalent influenza vaccine consists of three components: h1n1, h3n2 and victoria b. A fourth-priced influenza vaccine adds a type b yamagata unit. As a result, both the trivalent and the trivalent influenza vaccine are at risk of h3n2 infection and serious complications. There is no need to over-stretch the choice of the price of vaccines, and it is crucial that they be vaccinated and protected as soon as possible。
Q: what are the taboos on influenza vaccination
Response: vaccination is prohibited for persons who are allergic to any of the components of the vaccine or who have had a serious history of influenza vaccination; patients suffering from acute diseases, severe chronic diseases or acute onset of chronic diseases and fever are recommended for vaccination once they have recovered or stabilized; and patients who have been exposed to the greenbali syndrome within six weeks of vaccination against influenza are recommended for medical assessment and consideration for vaccination。
Q: what are the concerns after the flu vaccine
1. After vaccination, 30 minutes are required at the vaccination unit to confirm that there are no anomalies before leaving。
2. Keep the inoculations dry and clean within 24 hours and do not take showers and swim as much as possible. Drink more water, be careful to rest and avoid intense exercise。
3. In the event of swelling, pain or hypothermia in the inoculation area, special treatment is generally not required and may be self-depressed after cooling, drinking water and appropriate rest. In cases where body temperature exceeds 38. 5 °c, continued fever and local red edema, timely medical treatment should be provided。
