THURSDAY, Oct. 17, 2024 -- Folks who want solid protection during the cold and flu season should get the influenza vaccine now, the U.S. Food and Drug Administration says.The ideal time to get the flu vaccine is by the end of October, the FDA said in a news release.“Flu viruses typically spread in fall and winter, with activity peaking between December and February,” the agency added.

2024年10月17日，星期四——美国食品和药物管理局表示，在感冒和流感季节需要可靠保护的人现在应该接种流感疫苗。FDA在新闻稿中表示，接种流感疫苗的理想时间是10月底。该机构补充说：“流感病毒通常在秋季和冬季传播，活动在12月至2月达到高峰。”。

“Getting vaccinated in the fall can lower your chances of getting the flu.”Each year’s flu vaccine targets the three influenza strains that are most likely to circulate and cause illness in the United States, the FDA said.These strains are identified by watching flu trends in the southern hemisphere, where the wintertime cold and flu season is taking place while Americans are summering.“The flu vaccine will trigger your immune system to produce antibodies to protect against influenza disease -- it will not make you sick with the flu,” the FDA added.

“秋季接种疫苗可以降低感染流感的机会。”FDA表示，每年的流感疫苗针对的是三种最有可能在美国传播并引起疾病的流感病毒株。这些毒株是通过观察南半球的流感趋势来确定的，在那里，冬季寒冷和流感季节正在发生，而美国人正在夏季。“流感疫苗将触发你的免疫系统产生抗体，以预防流感疾病-它不会使你患上流感，”FDA补充道。

“It can take about two weeks after vaccination for antibodies to develop in the body, which is an important reason to get your flu vaccine early, before flu activity starts.”Folks need a flu shot each year because viruses mutate rapidly into new forms that attempt to evade previous immune protection, the agency explained.In addition, the protection provided by an annual flu vaccine diminishes over time, and might be too low to prevent a person from catching the flu this season, the FDA added.“Anyone can get sick with flu,” the FDA said.

“接种疫苗后大约需要两周时间才能在体内产生抗体，这是在流感活动开始之前尽早接种流感疫苗的重要原因。”该机构解释说，人们每年都需要注射流感疫苗，因为病毒会迅速变异成新形式，试图逃避以前的免疫保护。此外，美国食品和药物管理局补充说，每年一次的流感疫苗所提供的保护作用会随着时间的推移而减弱，并且可能太低而无法防止一个人在这个季节感染流感。FDA表示：“任何人都可能感染流感。”。

“Typically, children and people age 65 and older are most at risk of developing serious complications from influenza. In addition, pregnant people and those with certain chronic medical conditions are also most at risk of complications.”The U.S. Centers for Disease Control and Prevention estimates that during th.

“通常情况下，65岁及以上的儿童和人群患流感严重并发症的风险最大。此外，孕妇和患有某些慢性疾病的人也最有可能发生并发症。”美国疾病控制和预防中心估计，在流感期间。
