Initially approved by the Food and Drug Administration (FDA) in 2003, this recent approval extends a safe and effective vaccination option for individuals and their families to help protect themselves during flu season with no needles or waiting rooms. Now, for the first time, eligible individuals and their families can help protect themselves during the 2025-26 flu season from the convenience of their own home.²

Individuals 18 and older can visit www.FluMist.com to learn more and click to order, where they will be directed to complete a medical screening questionnaire. A licensed healthcare provider will review each submission to determine eligibility. Once eligibility is confirmed and insurance is verified, FLUMIST will be prescribed and shipped directly to the consumer's home on the date they had selected, complete with clear administration instructions, storage guidance and how to dispose.¹

Joris Silon, US Country President and Senior Vice President, AstraZeneca, said: "The launch of FluMist Home is a transformational moment in the evolution of influenza protection, bringing a simple and accessible option directly into the hands of consumers. FluMist Home reflects the growing importance of direct-to-consumer offerings and underscores our commitment to continuous innovation, making it easier for people to get vaccinated and stay protected."³

According to the Centers for Disease Control and Prevention, the 2024-2025 influenza season was classified as a high-severity across all age groups in the US–the most severe since the 2009 H1N1 swine flu pandemic, resulting in at least 610,000 hospitalizations and 27,000 deaths.^4-6 These trends underscore the importance of increasing influenza vaccination coverage and providing more accessible vaccination options to help improve immunization rates for protection against flu.

Ravi Jhaveri, MD, Division Head, Infectious Disease; Virginia H. Rogers Professor in Infectious Diseases, Professor of Pediatrics (Infectious Diseases), Northwestern University School of Medicine, Chicago, US, said: "As influenza vaccination rates decline, especially among younger populations, this first-of-its-kind, at-home, needle-free option offers a critical opportunity to help make protection more accessible, convenient, and better aligned with the realities and current preferences of people's lives."⁷

Michele Slafkosky, Executive Director, Families Fighting Flu, said: "Seasonal influenza can have a serious, even life-altering, impact on individuals and families, especially for those most vulnerable. Providing flexible vaccination options makes it easier for individuals and caregivers to help get protected. This can help to improve protection for individuals and strengthen collective immunity against influenza."⁸

Ami Patel, Executive Vice President, Hub Operations, ASPN Pharmacies, LLC, said: "For the first time, consumers can receive and administer an influenza vaccine entirely at home—marking a historic shift in how preventive care is delivered. Through FluMist Home we're seeing a new model of care that puts consumers in control, offering a seamless, end-to-end experience, from determining eligibility to convenient home-delivery and administration. This milestone not only redefines convenience in vaccine delivery, but also sets the stage for a more accessible, patient-centered future in healthcare."

Through FluMist Home, all orders will be reviewed by a licensed healthcare provider with ASPN Pharmacies, an independent online specialty pharmacy, and then dispensed and shipped by Polaris Pharmacy Services, a specialty pharmacy, in temperature-controlled packages to maintain cold chain continuity. Consumers can select their preferred delivery date during the ordering process for added convenience. FLUMIST for self- or caregiver-administration is packaged in a consumer-friendly format with clear, at-home specific instructions that support proper handling, administration, and disposal. Once received, the vaccine should be stored in the refrigerator until use. The service also ensures documentation of vaccination in the relevant Immunization Information System.¹

For the 2025-26 flu season, FluMist Home will be available in 34 states covering about 80% of the eligible population. There are a number of states where FluMist Home is unavailable due to local pharmacy laws. Our aim is to have this service available in all 48 contiguous states in future seasons. FLUMIST will continue to be available in doctors' offices and pharmacies for administration by healthcare professionals across the nation. More information on FLUMIST and FluMist Home is available at www.FluMist.com.

Human Factors Usability Study for FluMist Self-Administration

FLUMIST for self- or caregiver-administration was approved by the FDA in September 2024, following research demonstrating that individuals over 18 years of age can safely and effectively self-administer or administer FLUMIST to eligible individuals. In FDA-required human factors/usability studies, AstraZeneca evaluated if individuals 18 through 49 years of age could appropriately administer FLUMIST when given instructions for use. The results showed that 100% of intended users successfully administered a full dose.¹² In addition, data show that efficacy, immunogenicity and adverse events with self-administration of FLUMIST are similar to those seen with HCP-administered vaccination.¹³ The FLUMIST label has been updated to provide additional instructions on self and caregiver administration for eligible patients. Children 2-8 years of age with an uncertain vaccination history may not be eligible for caregiver administration and should consult their healthcare provider for further information.⁹
