Introduction
Do you need to get the flu vaccine every year? Generally, yes. The protective effect of the flu vaccine lasts about one year, so it should be administered two to three months before the peak flu season to effectively prevent influenza. Since there are many different viruses that can cause the flu, it is necessary to receive the flu vaccine each year during the high-risk season.

  打流感疫苗指的是接种流感疫苗,一般情况下,是否每年都要接种流感疫苗,需根据个人的Health状况和当前的流感病毒株进行判断,若有不适,Recommendation及时就医。具体分析如下:

  1、需要每年都接种

  流感病毒具有高度变异特性,如果是老年人、慢性病Patient以及孕妇等高风险人群,抵抗力较差,恢复速度较慢,Recommendation每年都接种流感疫苗,可以有效降低流感的患病风险。

  2、不需要每年都接种

  如果身体状况良好,Immunity系统抵抗力较强,恢复速度快,或是上一年接种的流感疫苗仍然对当前流行的病毒株提供足够保护,则不需要每年都接种流感疫苗。

  为避免对身体造成不必要的损伤,Recommendation在专业Doctor的指导下接种流感疫苗。在流感季节保持良好的个人卫生习惯,勤洗手,戴口罩,避免接触流感Patient,有助于降低感染风险。
