AstraZeneca's bid for approval of a self- or caregiver-administered option for FluMist Quadrivalent, a needle-free nasal spray, has been acknowledged for review by the US Food and Drug Administration (FDA). If greenlit, this vaccine would mark a significant stride as the foremost self-administered flu vaccine accessible to eligible patients or administered by caregivers, widening the spectrum of choices for influenza immunization.
Usability Study Validates Self-Administration
Supported by a usability study, the application confirms that individuals over 18 years of age could competently self-administer or administer FluMist to eligible patients aged 2-49 years when provided with usage instructions, sans additional guidance. FluMist, administered via nasal spray, boasts extensive data showcasing comparable efficacy and safety relative to other flu vaccines.
Anticipated Regulatory Decision and Availability
The Prescription Drug User Fee Act (PDUFA) date, marking the FDA's regulatory verdict, is slated for the first quarter of 2024. Pending approval, FluMist is expected to be procurable for self-administration in the US during the 2024/2025 flu season.
