[Technical guidelines for seasonal influenza vaccination in China (2020-2021)].
Influenza virus infection is a respiratory infectious disease that can seriously affect human health. Influenza viruses can have frequent antigenic variation and changes, which can result in rapid and widespread transmission resulting in annual epidemics and outbreaks in places of public gathering such as schools, kindergartens and nursing homes. The World Health Organization (WHO) estimated that seasonal influenza epidemics have caused an annual 3 to 5 million severe cases, and 290000 to 650000 deaths globally. ⋯ Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for use by staff members of the Centers for Disease Control and Prevention at all levels who work on influenza control and prevention, PoVs staff members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and staff members of maternity and child care institutions at all levels. These guidelines will be updated periodically as new evidence becomes available.
