It is the end of October again, and it is the time for influenza seasonal vaccination. The National Center for Disease Control and Prevention has just released the "Technical Guidelines for the Prevention of Influenza Vaccination in China (2019~2020)" (referred to as the "2019 Edition Guidelines"), which really gives benefits to the general public. The "2019 Edition Guidelines" is the National Immunization Program Technical Working Group of the National Center for Disease Control and Prevention of China's National Center for Disease Control and Prevention every year based on the influenza virus strain, immunogen, vaccine efficacy, vaccination effect, and vaccine safety. In "China Influenza Vaccination Prevention and Reception" Based on the application of the technical guide for genus (2018~2019)" referred to as the "2018 Edition Guide", scientific research, updates and revisions have been carried out to form a new guide. Here, the author introduces the main content of the new guide to more conducive to understanding and operation, so that everyone can get vaccinated:
1. The update content of the "2019 Edition Guide":
1. The new guide has increased the burden on influenza diseases, vaccine effects, vaccine safety monitoring, and vaccination costs in my country, which means that the current vaccination effect and safety are further guaranteed.
2. It added a series of policies and measures for influenza prevention and control by the National Health Commission from 2018 to 2019, thus providing policy guarantees for influenza prevention and control, which fully demonstrates the government's high attention to influenza prevention and control.
3. Updated the types of influenza vaccines approved and issued in my country from 2019 to 2020; as long as the vaccines approved and issued by the Centers for Disease Control and Prevention that have passed the national drug review, it is safe.
4, updated the 2019 trivalent and quadrivalent influenza vaccine components. That is, it once again clarifies the scope of application and vaccinated population of the vaccine;
also emphasizes that the "2019 version of the Guidelines" is suitable for the following three types of people to be vaccinated with influenza vaccine:
△ Staff at all levels of disease control centers engaged in influenza prevention and control;
△ Staff at vaccination sites;
△ Medical staff in pediatrics, internal medicine, and infectious departments of medical institutions at all levels, as well as professional and technical personnel in maternal and child health care stations at all levels.
2. The "2019 Edition Guidelines" propose that the population suitable for influenza vaccines is the following 6 categories:
Children 6 months old to 5 years old; elderly people aged 60 and above; patients with chronic diseases; medical staff; family members and nursing staff of babies under 6 months old; pregnant women or women who are preparing to get pregnant during the flu season, the above should be given priority for vaccination, and influenza vaccines can be received for people over 6 months old without contraindications.
Further explanation: Except for babies under 6 months of age and those with underlying diseases, all populations over 6 months of age are suitable for vaccination. Babies under 6 months old are not within the vaccination range because they have maternal autoantibodies.
3. Trivalent and quadrivalent influenza vaccine and vaccination methods:
1, Vaccination procedure for children aged 6 months to 8 years old:
First vaccination: Children of this age who are vaccinated with influenza vaccine for the first time should receive 2 doses (times), with an interval of ≥4 weeks;
Vaccination once: From 2018 to 2019 or before, children of this age who have received ≥1 dose of influenza vaccine can receive 1 dose last time (continue the last vaccination).
2, children and adults aged ≥9: only 1 dose is required.
3, the difference between trivalent and tetravalent vaccines:
The trivalent and tetravalent vaccines are both inactivated influenza vaccine . There is no difference between the titer and safety of the vaccine, but a subtype of influenza B is added to the quadrivalent vaccine strain. There is no significant difference in safety between domestic vaccines and imported vaccines. Both trivalent and tetravalent vaccines can play a preventive role in influenza. Therefore, there is no priority for which vaccine is recommended, and you can voluntarily choose trivalent or tetravalent vaccines.
my country Pediatric Association and the American APP (Pediatric Association) study, children under 3 years old are suitable for 3-valent vaccines, and children over 3 years old and adults are both trivalent and tetravalent.
Summary: In order to prevent and control influenza well, the country has conducted scientific research and demonstration of the technical guidelines for influenza vaccination every year and revised it. With the arrival of the annual influenza epidemic season, it is the responsibility of every medical worker to do a good job in prevention and control and vaccination. Influenza vaccination is not a problem of whether it is vaccinated or not. People over 6 months old should be vaccinated as long as there are no contraindications.
