On the 22nd, the National Health Commission held a press conference to introduce the relationship between seasonal solar terms and health (Chushu), and answered questions from reporters. At the meeting, a reporter asked: Vaccines are effective measures for preventing diseases. How do adults choose the appropriate vaccine for themselves? Zhang Li, chief physician of Shandong CDC, said that there are many kinds of vaccines available to adults in China, such as influenza vaccine, pneumococcal vaccine, COVID-19 vaccine, measles rubella mumps triple vaccine, hepatitis A vaccine, hepatitis E vaccine, cholera vaccine against intestinal infectious diseases, rabies vaccine, hemorrhagic fever vaccine and encephalitis B vaccine against animal borne infectious diseases. How should adults choose from so many vaccines? Zhang Li introduced that these vaccines can generally be divided into three categories. The first is the vaccines recommended for vaccination, except for those who are contraindicated. For example, for influenza vaccines, regardless of previous immunization history, it is recommended to receive one dose of this season's influenza vaccine; In addition, it is recommended that the elderly over 60 years old should be vaccinated with herpes zoster vaccine, pneumococcal vaccine and COVID-19 vaccine. The second is to mainly recommend vaccines for key populations, and the key populations for different vaccines are different. For example, it is recommended that patients with chronic liver disease, women of childbearing age, the elderly, students, military officers and soldiers, catering industry personnel, livestock breeders, and travelers from epidemic areas receive the hepatitis E vaccine. It is also recommended that personnel in areas with high prevalence of hemorrhagic fever receive the hemorrhagic fever vaccine. The third is vaccines administered under specific circumstances. For example, after being bitten by rabies host animals such as dogs and cats, it is recommended to receive rabies vaccine. In addition, it is necessary to determine whether to receive tetanus vaccine based on the condition of the wound and previous vaccination history. In addition, if traveling abroad, it may be necessary to receive yellow fever vaccine, cholera vaccine, or influenza vaccine according to the requirements of the country of entry. Zhang Li emphasized that when adults choose vaccines, they should consider factors such as age, health status, occupation, travel plans, and past vaccination history. For specific information, they can consult the local disease control center or vaccination unit. (New Society)
