Wang Heng, Chief of the Immunization Planning Section of the Erqi District Disease Prevention and Control Center of Zhengzhou City, told reporters that children are high -risk groups of influenza, and students' start time this year is rearranged with the time of flu, so the number of children with influenza has increased significantly.

"There are many types of influenza viruses and are prone to mutation. The annual pools that are popular each year are not the same, and the strains of the flu vaccine are different every year. Therefore, inoculation of influenza vaccine is one of the most effective means to prevent influenza." Wang Heng introduced it. In my country, the influenza vaccine that has been approved by China mainly includes injection -type three -valent influenza vaccine, quadrimal influenza vaccine and nasal injection three -valent drug reduction vaccine. The three -valent influenza vaccine contains two types of A flu virus strains and a type B influenza virus strain, which can prevent three types of influenza of H1N1, H3N2 and B -type V series.

The high -risk population is recommended to take vaccination as soon as possible

Wang Heng reminded that in addition to children, the elderly and patients with chronic diseases at the age of 60 and above are also high -risk groups of influenza. Some patients do not know the flu. They think it is just a normal cold. In fact, fluctuations are a kind of acute respiratory disease caused by the flu virus. It has strong infectiousness. The main symptoms are fever. Deficiency such as systemic symptoms, body temperature is usually above 38.5 ° C. If the treatment is improper, pneumonia may cause pneumonia or even life. Ordinary colds are a common acute upper respiratory virus infectious disease. It has mild systemic symptoms and can be treated with normal cold medicine.

When a high -risk population is vaccinated, it should be noted that the flu vaccine does not take effect immediately after vaccination. Generally, it takes 10-15 days to produce protective antibodies. The protective antibody generated after vaccination can last about 1 year. From October to March of the following year, it is the epidemic season of influenza and other respiratory tract infectious diseases. Therefore, it is recommended that you vaccinate flu vaccines in mid -late September. If you have not been vaccinated yet, it is recommended to take vaccination as soon as possible.
