As a result of an autumn rain, the flu season is getting closer and closer. Should we fight the flu vaccine? When's the best time? Have you ever had a flu? Do you need a flu vaccine? The representative of the health section will make it clear for you once
Influenza is an acute respiratory epidemic caused by influenza viruses, which seriously endangers human health, mainly in the form of fever, headaches, myocardia and general discomfort, with symptoms of accommodative acidity, inactivity and appetite. Currently, the most cost-effective technical method of preventing infectious diseases is vaccination。
You're in good health. Do you need a flu vaccine
Influenza virus, popular. The clinical symptoms of influenza are more severe and contagious than the usual flu, and there is a corresponding increase in the risk of complications such as viral pneumonia, secondary bacterial pneumonia, respiratory failure and heartitis. Therefore, timely vaccination against influenza is recommended for those aged 6 and above who are not inoculated。
Who needs to give priority to influenza vaccine
The first category is focused on the population, mainly those aged 60 years and over, as well as those suffering from chronic diseases. Such populations are less immune and are given priority if they are exposed to serious complications such as pneumonia, cardiovascular disease and possibly aggravated by pre-existing underlying diseases. Secondly, there are infants and children over the age of june. The immune system for infants and young children is not yet fully developed, and influenza vaccines tend to give rise to a high risk of heat convulsions, pneumonia and encephalitis, and, if infected, may cause a concentrated epidemic in child-care institutions or schools。
The second group of persons to be given priority is those working in priority institutions or places, including medical institutions, nursing institutions, care institutions, welfare institutions, etc., and families of infants under six months of age. When they are vaccinated against influenza, they are able not only to prevent their own infection, but also to protect those who are vulnerable to serious illness after infection, so priority is given to vaccination。
Is there a perfect time for a flu vaccine
The influenza vaccine will produce antibodies in 2-4 weeks. Annual peaks in influenza activity vary in time and duration throughout the country, and, in general, vaccinations in the months of january to february before the onset of the high influenza season (autumn winter festival) are the best option. If vaccination is not completed before the onset of the epidemic season, it is available throughout the epidemic season。
Last year, you were vaccinated against influenza. You want to be vaccinated this year
On the one hand, influenza viruses are susceptible to mutation, and each year the strains may vary. Therefore, our country, based on national influenza surveillance data, will re-advertise the recommendations of the annual influenza vaccine strain published by the world health organization to adjust the influenza vaccine components produced during the season so that the vaccine can match the antigens of our epidemic strain as far as possible。
Second, as we are vaccinated against influenza, the level of antibodies produced in the body will decline over time, and thus will require annual vaccinations to achieve better protection。
Why do we have to be vaccinated after the flu
On the one hand, the influenza virus has a wide variety of types, and the only antibodies produced in the body are those that work. On the other hand, antibody protection in the body is not sustainable after infection, and vaccination can further enhance the level of antibody protection。
Will the flu be inoculated
The effectiveness of any vaccine protection is not 100 per cent. Inoculation against influenza is not guaranteed, but can significantly reduce the risk of infection and serious illness。
Where's the flu vaccine
Influenza vaccination services are provided by vaccination units located in community health centres, townships or general hospitals. You can use the sichuan vaccination (sichuan vaccination) microclinical public number to obtain information about specific units。
