2024年10月26日，星期六——既然美国食品和药物管理局已经批准在家使用流感疫苗喷雾剂，你怎么知道它是你和你家人的正确选择？一位专家就喷雾剂的功效以及如何确定FluMist是否是您对抗流感病毒的最佳选择提供了建议。

Importantly, the spray will not be available for use in homes until the fall of 2025.FluMist was first approved for at-home use in September by the U.S. Food and Drug Administration. Right now, only healthcare providers can administer the spray.So, exactly what is FluMist?It is a live influenza vaccine containing a weakened flu virus for the three prominent vaccine strains.

重要的是，这种喷雾要到2025年秋天才能在家中使用。FluMist于9月首次被美国食品和药物管理局批准在家中使用。目前，只有医疗保健提供者才能使用喷雾。？它是一种活流感疫苗，含有针对三种主要疫苗株的弱化流感病毒。

It’s approved for children as young as 2 and for adults up to age 49.“Instead of an injection, there is a live vaccine administered by spray into the nose to give a good immune response, so that the nose and respiratory system is better prepared against influenza,” said Dr. Pedro Piedra, professor of molecular virology and microbiology and pediatrics at Baylor College of Medicine in Houston.

它已被批准用于2岁以下的儿童和49岁以下的成年人。休斯顿贝勒医学院分子病毒学、微生物学和儿科教授佩德罗·皮德拉（PedroPiedra）博士说：“有一种活疫苗不是注射，而是通过喷入鼻子来产生良好的免疫反应，从而使鼻子和呼吸系统更好地应对流感。”。

While Piedra says the FluMist spray is intended for healthy children and adults, it also works for needle-shy people. “The immune response is good for both children and adults. Like all vaccines, there could be a local reaction for a small percentage of people – this could be a mild cold, a runny nose or soreness in the throat because the virus is alive and replicates in the nasal passage,” he said in a Baylor news release.

Piedra说，这种喷雾器是为健康的儿童和成人设计的，但它也适用于怕针头的人。他在贝勒新闻稿中说：“免疫反应对儿童和成人都有好处。像所有疫苗一样，一小部分人可能会出现局部反应，可能是轻度感冒、流鼻涕或喉咙酸痛，因为病毒还活着，并在鼻道中复制。”。

When it comes to effectiveness, Piedra said FluMist works as well as the inactivated vaccine for the age range it is intended for. However, the spray isn't for immunodeficient or immunocompromised people. Also, the spray could cause wheezing after administration in children un.

Piedra说，就有效性而言，FluMist与灭活疫苗一样适用于预期的年龄段。然而，这种喷雾不适用于免疫缺陷或免疫缺陷的人。此外，喷雾剂在儿童服用后可能会引起喘息。
