Monitoring data from the National Influenza Center shows that at present, the northern and southern provinces are still in the high incidence season of influenza. "Minors, the elderly, etc. are at high risk of influenza." Professor Hu Dandan, director of the Guangdong Provincial Special Needs Vaccination Clinic of Guangzhou Women and Children's Medical Center, said in an interview with reporters, "For children with special needs, such as children with congenital heart disease, chronic lung diseases and other basic diseases, we often recommend parents to give their children priority to influenza vaccination to reduce influenza virus infection." At the same time, if students have symptoms such as fever and cough, they may be isolated at home at home, and may result in school closure. Therefore, influenza vaccination is the most cost-effective means of preventing influenza. ”
At present, according to the different components contained in the vaccine, the continental influenza vaccine is divided into trivalent and quadrivalent. Hu Dandan introduced: "The trivalent mainly includes the H1N1, H3N2 and Victoria series in influenza B viruses in influenza A virus, while the quadrivalent is to add the Yamagata system in influenza B virus on the basis of trivalent. That is, quadrivalent vaccines have a more comprehensive protective effect than trivalent vaccines. ”
According to the information released by the Guangdong Provincial Special Needs Vaccination Clinic of Guangzhou Women and Children's Medical Center, there are currently trivalent influenza lysis vaccines (children's dosage forms) and Hualan Biological Quadrivalent Influenza Vaccine (people over 3 years old) in Beijing Kexing. Hu Dandan said: "Hualan Biological Tetravalent Influenza Virus Lysis Vaccine was approved for marketing, which can be used for the prevention of related types of influenza in people aged 6 months to 3 years old, with wider coverage and the scope of vaccination expanded to people over 6 months of age." ”
The reporter learned that in addition to the influenza vaccine of Hualan Biologics, recently, the quadrivalent influenza virus lysis vaccine of the Shanghai Institute of Biological Products and the quadrivalent influenza virus lysis vaccine of Sanofi Pasteur have been accepted by the Drug Evaluation Center of the State Drug Administration and have been included in the priority review and approval list.
Experts recommend aggressive vaccination to reduce the incidence of influenza in children
According to the Mainland's Technical Guidelines for Influenza Vaccination (2020-2021), influenza vaccines are Class II vaccines (self-funded vaccinations) in mainland China, and the current average annual vaccination rate is only 2%-3%. According to industry experts, the reasons for the low vaccination rate include insufficient public awareness of influenza and influenza vaccines, less recommendations from medical staff, and the availability and cost of vaccination services. It is understood that at present, the unit price of Hualan Biological Quadrivalent Influenza Vaccine (people over 3 years old) is 128 yuan, and the unit price of Beijing Kexing's trivalent influenza lysis vaccine (children's dosage form) is 30.73 yuan.
Hu Dandan said that the target population of influenza vaccination has been expanded to people over the age of 6 months who are willing to vaccinate and have no contraindications, but the influenza vaccination of minors is affected by a variety of factors, among which parents' cognition and vaccination attitude towards the seasonal influenza vaccine of minor children play a crucial role. She suggested that vigorous publicity should be promoted so that parents can understand the protective role of influenza vaccination for preschool children, and actively vaccinate their children against influenza, thereby reducing the incidence of influenza in children on the mainland.
