流感噴鼻疫苗（LAIV）屬於減毒活疫苗，僅適用於 2 至 49 歲且健康狀況良好的個體。使用時應正常呼吸，不需深吸氣，以免藥物直接進入下呼吸道導致肺炎或其他不適。由於其含有減毒活病毒，對於免疫功能受損者（如愛滋病、癌症化療病人）或孕婦屬於禁忌症，因為活病毒可能在這些免疫力低下或脆弱族群體內過度複製造成感染。護理師必須嚴格篩選適用對象，以確保安全性。
The intranasal influenza vaccine (LAIV) is a live attenuated vaccine and is only indicated for healthy individuals between 2 and 49 years of age. When administered, the recipient should breathe normally, without deep inhalation, to prevent the vaccine from going directly into the lower respiratory tract, which could cause pneumonia or other adverse effects. Because it contains a live attenuated virus, it is contraindicated in immunocompromised individuals (such as those with HIV/AIDS or undergoing cancer chemotherapy) and pregnant women, since the live virus may replicate excessively in these immunosuppressed or vulnerable populations and cause infection. The nurse must screen candidates strictly to ensure safety.
