0.1 ml
can prevent influenza!
In the future,
children aged 3 to 17 who meet the vaccination conditions can use this method without pain throughout the whole process
to complete influenza vaccination
On August 28, the first domestic live attenuated nasal jet influenza vaccine began to be vaccinated at Wulong Community Health Service Center in Chenggong District, Kunming City. In the future, people can make appointments for vaccination in the local community vaccination clinic in Yunnan.
Unlike the familiar vaccine for the public, the live attenuated nasal spray influenza vaccine has changed the original vaccination method and is vaccinated by nasal spray administration (0.1ml is sprayed into each of the nostrils). Although there is no need to get an injection, like other flu vaccines, the vaccine also needs to be vaccinated once a year, one dose is given at a price of more than 300 yuan.
According to statistics, influenza can cause 20% to 30% of children and 5% to 10% of adults every year. The nasal spray influenza vaccine has been widely used in developed countries, and the live attenuated nasal spray influenza vaccine has been used worldwide by hundreds of millions of doses.
In 2011, with the permission of the WHO, the live attenuated nasal spray influenza vaccine technology was transferred to China. Currently, there is only one manufacturer in China.
nasal spray live influenza vaccine works in three ways: mucosal immunity, cellular immunity and humoral immunity, and can be immune to influenza viruses present on the nasal mucosa, intracellular and in the humoral fluid.
Relevant clinical trials abroad show that since the live attenuated influenza vaccine contains all influenza virus antigens, it is likely that it will have a cross-protective effect on multiple subtypes of influenza viruses during the immune process, thereby more effectively responding to the variable characteristics of influenza viruses.
Experts suggest that key groups such as kindergarteners, primary and secondary school students, etc. receive influenza vaccination in advance, and the public can choose to receive vaccination according to their needs. If you are allergic to vaccine components, or are receiving immunosuppressive treatment, and suffer from epilepsy and other neurological diseases, rhinitis, or fever, it is not advisable to choose to use it.
